INSPECTION DATES: June 14 & 16, 2000
INTRODUCTION:
As part of its expansive distribution system, the MDC maintains many storage facilities
to augment the daily potable water demands of its customers. The initial gravity system
has 6 underground storage basins and 3 standpipes.As the MDC expanded its service to
outlying sections in elevated areas of the towns served,it found that it had to use pump
stations to boost system pressure to properly serve their customers. To meet these new
demands, 16 pump stations have been constructed over the years. Some have their own
hydropneumatic storage tanks and some pump directly to one of the 7 above ground
tanks or a single below grade reservoir.
It should be noted that all of the storage tank/basin sites,when not directly on MDC
property,have security fences or access roads with lockable gates.
As a check on the stored water quality, heterotrophic bacteria plate count(HPC) and
physical samples were taken at each site visited. A free chlorine residual was also
recorded at the time of sampling.All the results were quite satisfactory and are
appended at the end of this report.
Superscripted numbers (1), correspond to numbers in the Conclusions and
Recommendations Section.
I. Underground Storage Basins/Reservoirs
A) Cedar Mountain Reservoirs-Hartford (south end)
These 2 identical (191111 x 137'w x 271h) 5MG concrete basins were built in 1951.
Their inspection hatches were not removed for lack of a key but it is suspect that,
like the Wickham Basins listed below,these inspection ports may also lack tight
1
fitting 24mesh circular screens to keep out insects,debris and small mammals
that would fall into the water the hatch is opened. (1)This in turn could increase
the chlorine demand of the stored water and reduce the effectiveness of chlorine
in eliminating pathogenic bacteria.
The basin's floors are at elevation 264.50, a stored water height of 27 feet results
in an overflow elevation of 291.0. The basin overflows are equipped with two
weighted flapper valves that discharge through metal grates to a drainage
channel.
The basins each fill and discharge in parallel by means of 30-inch lines that join
into a common 42-inch line that goes to distribution. The upper house contains
the 30-inch gate valves and some instrumentation for the basins. The lower
house still contains an old chlorinator,the new sampling compliance point and
chlorine autoanalyzer. The basins were last drained,cleaned and inspected in
12/95.
Water sample results: HPC count-less than 1 colony/ml,turbidity-less than
0.2NTU and free chlorine residual-0.24ppm.
B) Wickham Hill Storage Basins-East Hartford
These 2-2.25MG concrete basins are equal in size(11711 x 117'w x 23.251h) but
are at different elevations. The lower basin floor is at elevation 236 with basin
full at elevation 257. The upper basin bottom is at elevation 258 with overflow at
elevation 280.A discharge out the upper basin vent is often experienced as a
paved drainage swale has been constructed to carry water away from the vent
pipe and minimize erosion. (2)The basins have a 24"influent line and discharge
through a 16"line to distribution. Both tanks operate as one as the upper basin is
the only one that feeds the distribution system. The lower basin has a 3HP-
transfer pump that circulates water between the basins to keep the lower basin
water fresh and transfers water to the upper basin when the water level begins to
drop in response to a large system demand.
The basins when constructed in 1950 were equipped with vents and inspection
hatches on the basins' roof. The vents have been retrofitted with lockable
disinfection ports that can receive sodium hypochlorite for periodic disinfection.
The lockable heavy metal inspection hatches do not have screening but seem to
rely on a light metal circular plate that fits in the hatch opening underneath the
primary cover to keep out debris, insects and small mammals. This secondary
cover had holes in it and when the cover was exposed,2 discarded snakeskins and
large populations of insects were discovered. This cover does not appear to be
adequate to keep debris and contaminants from falling into the basin. It is
suspect that the upper basin is similarly vulnerable. (1)The basins were last
cleaned and inspected in 1996.
2
Water sample results (lower basin): HPC count-less than 1,turbidity-less than
0.2NTU and free chlorine residual-0.38ppm; (upper basin)-HPC count-8,
turbidity-less than 0.2NTU and free chlorine residual-0.44ppm.
C) Cold Brook Basins/Pump Station-South Glastonbury
These 2-0.25MG identical(541 x 81'w x 7.66'h) concrete basins were built in
1920. Base elevation is 240.55 with top, basin overflow at 248.75. The basins are
gravity fed through a 1611' line. Pump station discharge is via a 12"line that
serves the Bucks Corner section of south Glastonbury.
Pumps transfer water from the basins to 4-400 gallon pressure tanks that supplies
Bucks Corner with first stage pressurized water. The tanks are equipped with
drains,pressure gauges,sight glasses and air relief blow-offs. One tank was off-
line at the time of inspection.The pumps (2-15hp, @ 85gpm) operate on an
alternating lead/lag basis to equalize pump usage. These run times were
confirmed by viewing the pump totalizing hour meters for each pump. They were
similar. It should be noted that it is standard practice by MDC to have all pump
stations be equipped with hour meters for each pump on=site.The station's
operating pressure range is 100-135psi. The station has an oil fired 125 kW diesel
generator on-site for emergency power. It also has a electrical outside socket for
an off-site generator.This dual emergency power capability is provided at all the
MDC pump stations. The basins were last drained and cleaned in September of
1999.
Water sample results: HPC count-20, turbidity-0.2NTU and free chlorine
residual-0.03ppm.
MDC may inactivate this station once the New London Turnpike main extension
to South Glastonbury is complete.
D) Eastbury Basin-Glastonbury
This circular(75.5'D x 15'H)prestressed concrete 0.5MG tank was constructed in
1972. Its bottom elevation is 405' with overflow at elevation 420'. The overflow is
hardpiped to a storm sewer catchbasin. It is unknown if this discharge is
screened. (3)The basin is filled from the Orchard Street pump station via a
common 12"fill/discharge line. The basin is equipped with a locked and screened
mushroom access hatch located to the rear of the basin. A below grade vault to
the front of the basin contains radio telemetry equipment, a sample tap and
altitude valve. High and low level signals are radioed back to the central office.
The last inspection date is unknown. (14)
Water sample results: HPC count-1, turbidity-0.6NTU and free chlorine residual-
0.01ppm.

IL Storage Tanks/Standpipes
All of the tanks in the distribution system"ride" on the daily pressure demands
of the system.When system demand is down the tanks fill,usually at night, and
when system demand increases, the tanks drain,usually in the daytime. The
tanks rarely overflow.
None of the tank overflows could be located,with the exception of the Canal
Road tank and the Kilkenny Rocks tanks.Their overflows were found
unscreened which is in violation of section 19-13-11102 (f)(3) of the CT Public
Health Code that has been quoted previously in this report.(4)
As is stated in section 7.0.18 of the Recommended Standards For Water Works
"Appropriate sampling tap(s) shall be provided to facilitate collection of water
samples for both bacteriologic and chemical analyses. Properly installed sample
taps were not found at the Canal Road or Rocky Hill tanks. (5)
A) Rocky Hill- 0.45MG Standpipe
This riveted steel tank was built in 1932 with a diameter of 301and height of 851.
Its floor elevation is 202' with overflow/top water at 287'. Its overflow is internal,
its discharge point was not found. It was not determined if the overflow pipe was
screened. It has a below grade vault that contains an altitude valve. It fills and
discharges through a 10" line. According to MDC it was last painted inside in
1977 and outside in 1990. (14)It is due for an inside repainting this year. The tank
is exhibiting evidence of rust around some exterior rivet heads and plate overlaps.
Water sample results: HPC count-100 colonies/ml; turbidity-0.3NTU and free
chlorine residual-0.04ppm.
B) Newington- 0.31MG Standpipe
This welded steel tank was built in 1948 and has a diameter of 27' with a height
of 70'. The tank floor elevation is 224.50' with an overflow/top water elevation of
294.50'. The water level in the tank on the day of inspection was almost to the top
of the 6th ring(approx. 52'AGL) around 11:30AM. The tank's internal overflow
discharge was not found.And it was not determined if the pipe was screened. The
tank fills & discharges by means of a single 10"line. The tank's perimeter fence
has been broken down in spots and the area has evidence of trespass and
vandalism. The tank's lower rings show excessive graffiti and rust spots due to
rock throws (6) It was last painted both inside and out in 1981. A repainting of
the inside is scheduled for this year. (14)
Water sample results: HPC counts-1,turbidity-0.2NTU and free chlorine
residual-0.11ppm.
C) Windsor(Day Hill)-0.5MG Standpipe
This welded steel tank was placed into service in 1950 and has a diameter of 32'
4
with a height of 80'. Its base elevation is 214.50' with an overflow/top water
elevation of 294.50'. Its internal overflow discharge point is unknown. It was last
painted inside in 1997,the outside was done in 1984. It was last drained &
inspected in 11/94.(14)The tank fills and drains through a single 12"line. Both
underground valve vaults were flooded with 2-3 feet of standing water,which is
peculiar as the tank and security fencing is on a knoll highly elevated from the
surrounding terrain.The gravity drains appear to be blocked. (7)The exterior
paint is good condition. Some surficial spalling of the concrete pad was noted.
Water sample results: HPC count 1; turbidity-less than 0.2NTU and free chlorine
residual-0.27ppm.
D) Canal Road (W. HFTD.)-0.5MG
This prestressed concrete tank was put into service in 1961, has a diameter of 58'
and height of 251.Its base elevation is 425' and has a top water/overflow elevation
of 450'. The internal overflow pipe discharges down a hillside and is unscreened.
The tank does not appear to have a sample tap.(4)�(5)It fills and discharges
through a single 12"line. The large lateral crack noted in the last report has been
repaired. It was last drained and inspected in 6/95.
Water sample results: not taken.
E) Kilkenny Rocks (W. HFTD.)-Standpipes(2)-ea.@0.5MG
These 2 identical welded steel storage tanks were built in 1967. Each tank has a
diameter of 45' and a height of 41'. Their floor elevations are 499' with an
overflow/top water elevation of 540'. Their external overflows share a common
line that discharges to an adjacent brook. It is unscreened. Each tank has a
sample tap. There is an old air compressor on site that was used for a,now
inactive, air bubbler system.($)The tanks were last painted in 1985. The tanks are
in need of painting now and bids are being prepared for this project. They were
last drained and inspected in 1990.(14)The tanks fill and discharge through a
common 16"line.
The tanks are filled from the Hawley Road pump station that is part of the Slow
Sand Plant Administrative Building. The station contains 3 horizontal split-case
500GPM pumps that activate sequentially as water levels in the tanks drop. Pump
#1 activates as levels drop to 36-411,pump#2 at 31-39' and pump#3 at 26-371.
The pumps are powered by 1-60HP and 2-75HP electric motors.There are also 2-
60HP and 1-75HP electric motors on site as spares.
5
The pumps are alternated regularly but pump#1 has a far greater total run time
than either#2 or 3. There is also a 40KW Detroit diesel powered 2200GPM pump
on hand for standby power. The diesel is exercised on a monthly basis. This
station is to be upgraded should MDC sell water to the Unionville Water
Company in the future.
Water sample results: HPC count-1 colony/ml; turbidity-less than 0.2NTU and
free chlorine residual-0.10ppm.
F) Vexation Hill(Rocky Hill) Storage Tank Farm(4)-Total 3.39MG
All 4 tanks fill and discharge equally through a common 16"pipe. A distribution
compliance sampling point has been created here by the installation of a common
sampling hydrant by the access gate that will represent water from all four tanks.
The first 2 identical welded steel 0.75MG tanks were constructed in 1964,with a
diameter of 70' and a height of 261. Their floor elevations are at 384' with
overflow/top water elevation at 4101. Both were painted inside in 1979 and
outside in 1992. Both tanks are now experiencing defoliation of the finish coat
with exposure of the primer coat to the weather.(9)The external overflows are
piped directly into individual catch basins. The common overflow discharge point
was not found and it was not determined if it was screened.There was extensive
grass growth around the tank bases, making leaks/weeps at the base difficult to
discover if occurring.(10)There is some spalling of the concrete pads in evidence.
A third 0.89MG tank was constructed in 1984. It is a glass coated bolted steel
tank, that does not require painting,with a diameter of 81' and height of 23'. Its
base elevation is 385.20' with an overflow/top water elevation of 4081. Its double
weired unscreened overflow discharges 24" above its catch basin.(I) It, along with
#1&2,was last drained and inspected in 5/90.(14)
The fourth last and largest tank was built in 1994.It is of the same design as
Tank#3 and its diameter of 81' and height of 261 gives a total volume of 1.00MG.
It base elevation is 384' with an overflow/top water elevation of 410'. It also
discharges its overflow through a 24" air gap to a catch basin. The overflow
outlet is unscreened. (1)It has not been drained or inspected since it was
constructed. (14)
These 4 tanks are supplied water from the Newington and Wethersfield pump
stations.
Water sample results: HPC count-less than 1 colony/ml; turbidity-0.2NTU and
free chlorine residual-0.25ppm.

III. Hydropneumatic Tank Pump Stations
It should be noted that all of the stations visited were alike in the following
ways:
• all the stations are well maintained, heated,lit and drained
• each station had at least 2 means of emergency power, an on-site generator
and an external receptacle for a portable unit,the generators are maintained
and exercised regularly by MDC staff(11)
• each station has a high (discharge) and low (suction)hydrants,for emergency
station bypass
• totalizing hour meters for all pumps are at each site
• the stations use alternating lead/lag activation of the pumps, as proven by the
above meters showing similar total pump run times
• tank air relief valves, drain valves and pump volute air release pet cocks are
all hard piped to the station drain, minimizing condensation within the station
• all stations have automatic air compressors to replenish lost air in tanks
• all pressure tanks are equipped with; a drain,pressure gauge,inspection
manhole, sight tubes with marked operational pump on/off water levels and
air relief valves
• all stations have radio telemetry that send alarm signals (AC Power, generator
activation, flooding,tank low/high pressure,pump activation) to the main
office at the MDC sewage treatment plant in Hartford
• all tanks are cleaned and inspected every five years and,painted when needed
• pursuant to a letter of 11/23/99,MDC will thoroughly flush all pump station
hydropneumatic tanks annually(12)
The pressure tanks are utilized with about 40% of useable tank water volume
that results in a large air/water interface area in the tank. This may lead to
entrained air in the water exiting the station resulting in pump cavitation and
milky water complaints. To preclude this from happening each tank discharge
line is equipped with a specialized low pressure cut-off valve that prevents any
air from exiting the tank during a very low water pressure event, e.g. a main
break or fire emergency.

CONCLUSIONS and RECOMMENDATIONS:
1) Sections 19-13-B102 (f)(3) of the CT Public Health Code states in part, "All water
storage tanks connected to a public water distribution system shall be constructed
and located so as to adequately protect the water from contamination.Tanks and
basins must be covered and vents and overflow pipes screened. They shall not be
directly connected to sanitary sewers or to storm drainage systems."
Any and all inspection hatches for the Cedar Mountain,Wickham Hill,Eastbury
and Cold Brook Basins should conform to this requirement.
2) This overflow condition was noted in the 1995 sanitary survey. A telemetered signal
(high level/overflow) should be installed at the Wickham Hill upper basin to prevent
or at least minimize this repetitious overflow.
3) While the CT Public Health Code prohibits direct connection of the overflow pipe to
any sewer, see item#1,the differences in elevation between the Eastbury basin and
storm sewer would preclude any backpressure into the basin and,the mushroom
vent would preclude any backsiphonage into the basin.
4) In addition to above cited code requirement, section 7.0.8d of the"Recommended
Standards For Water Works" also requires screening of the overflow pipes. Its
purpose is twofold: first to prevent small mammals/insects from entering the tank
and second,to catch any floatable material,e.g. leaves/bird feathers, in the overflow
discharge that would be indicative of tank contamination. It must be verified by
MDC that all storage tank and basin overflows are screened in accordance to Public
Health Code requirements.
5) The finished water storage section 7.0.18 of the "Recommended Standard For Water
Works" states, "Appropriate sampling tap(s) shall be provided to facilitate collection
9
of water samples for both bacteriologic and chemical analyses."All storage tanks
and pumping stations should be so provided.
6) The security fence at the Newington standpipe should be repaired and the tank's
exterior scheduled for repainting.
7) Submerged potable water piping/valves are considered a cross connection pursuant
CT Public Health Code section 19-13-B37a and 19-13-1151c.The drains in the below
grade pits at the Day Hill standpipe should be cleared and the pits maintained in a
dry condition.
8) The unused air compressor at the Kilkenny Rocks tanks should be put to use
elsewhere or sold as surplus.
9) Vexation Hill Tanks#1&2 should be scheduled for repainting in the near future.
10)Grass and shrub growth around storage tank bases should be kept to a minimum to
facilitate tank leak inspections.
11)All-emergency generators and diesel engine powered pumps should be exercised
pursuant to DPUC regulation sec. 16-11-99a(d),i.e. "at least once in every
consecutive 30 day period, under load, for a minimum duration of 30 minutes".
12)As set forth in section 19-13-Bl02(f)(5) of the CT Public Health Code, "The
distribution system shall be flushed as required to maintain it free from excessive
accumulation of sediment, organic growths,products of corrosion and erosion, and
other extraneous matter". It is recommended that MDC flush all of its
hydropneumatic tanks on a semi-annual basis,preferably after the spring and fall
hydrant flushing programs.
13)The CT Public Health Code requires, at a minimum, annual testing of all backflow
devices, e.g. RPDs. MDC is now tagging all their RPDs at their various facilities.
This tag would show the last test date and functioning status of the device. The
devices in the pump stations should be included in this program.
14)According to AWWA Standard D-101-53 (Revised 1986), "..all water tanks
(including storage basins) should be thoroughly inspected at intervals of not more
than five years". According to this acknowledged schedule, many, if not all of MDC's
storage facilities are overdue for inspection.This office would urge MDC to
accelerate its storage tank/basin inspection program in order to conform to industry
standards.

Dear MrrPeVVula;
Enclosed is the MDC/DPH flushing letter that I have previously
discussed with you. It is less technical and more consumer friendly
than the draft letter I had sent you. Both this office and the MDC
have had input on this final version. It should go out this week.
I have enclosed a few pages of information of a technical nature
that your office can use should you receive any inquires. You may
want to share this letter and information with other town
officials.
This mailing will go to all the condominium associations or their
management companies in South Windsor that are be served by the
MDC.
If you have any questions please call me. Thank you.

Aesthetic measures(discolored water,taste and odor,temperature)
• Other measures(corrosion indices,lead and copper concentrations,
disinfection by-products)
Bacteriological Measures
Monitoring and control of bacteriological measures in the distribution
system are required by the SDWA,its amendments,and various rules associated with
it.The Total Coliform Rule(TCR)requires measurements of total coliform bacteria,
HPC, and disinfectant residual in a specific number of locations in a distribution
system.Assessment of bacterial regrowth potential(with parameters like assimilable
organic carbon,biodegradable organic carbon,and direct measures of biofilms)can
be used to investigate the nature and causes of bacterial quality deterioration in the
distribution system.
The maximum contaminant level goal(MCLG)for total coliforms is zero.
The maximum contaminant level(MCL)is based on the presence or absence of total
colifonns.For utilities analyzing at least 40 samples per month, no more than 5.0
percent of the monthly samples may be positive for total coliforms. Three repeat
samples must be collected within a 24-hour period for each positive sample.HPC
testing is required by the TCR for samples with negative total coliforms to check for
heterotrophic bacteria interference. HPC may also be used to assess bacterial
regrowth in distribution systems.Residual chlorine at various locations in adistribution
system is also an important parameter.Absence of residual chlorine in.'a distribution
system is a violation of the TCR.The SWTR specifies contact time values in various
locations in a distribution system.
The terns bacterial regrowth and biofilm formation refer to the growth of
bacteria in the distribution system after disinfection.Many water systems consider
bacterial regrowth an existing or potential problem. Bacterial regrowth occurs
generally at low water velocity,at relatively high water temperatures,and at places
Where large surface areas are available for growth. In unlined old cast iron mains,
where cast iron corrodes in water and is redeposited in the form of surface tubercles,
the corrosion products that accumulate on the metal surface will provide greater
surface area for bacterial attachment and growth-if the deposits are not removed by
the.flowing water. Donlan et al. (n.d.), in their experiments at the Philadelphia
Suburban Water Company's distribution system, found that the rate of biofrlm
formation increased in warm water and decreased in cold water.They also found that
the rate of growth is related to flow velocity;the higher the flow velocity the lower
the growth,and vice versa.High velocity was found to shear attached cells from the
metal surfaces and to increase exposure of attached bacteria to residual disinfectant.
Another factor that affects bacterial regrowth in distribution systems is assimilable
organic carbon(AOC)in waterin the distribution system.Increase of AOC can cause
bacteria to increase over time throughout the distribution system.Removal of AOC
at the treatment plant may reduce bacterial regrowth in the distribution system.The
following conditions may lead to a high potential for bacterial regrowth in the
distribution system:
Tuberculation in unlined old cast iron mains with dead ends
• Warm summer water temperatures
• High levels of AOC in finished water
• Absence of residual disinfection
• Low velocity

William Aman,Mayor
Town of South Windsor
Sullivan Avenue
South Windsor Ct, 06074
Dear Mayor Aman,
The purpose of this letter is to gain your support in our petition to The Metropolitan
District(MDC) for construction of a water main on Newberry Road to complete public
water service to all properties on Newberry Road.
We originally petitioned the MDC in 1987 shortly after drilling our well and determining
the water quality to be less than satisfactory. Please refer to attached copy of our letter to
the MDC.
At the time of our original petition we were informed verbally by Luis Alvarado that
additional construction of water services in South Windsor was unlikely since South
.Windsor was not a member towri of the AMC.,We received no written response to our
petition but were told that itf would-be considered in'the quarterly planning meetings held
by the MDC.
Recently, late in 1995 or early 1996,the MDC proceeded with construction on Main
Street in South Windsor, Again verbally, we were advised that this construction project
would benefit us in that the closing or joining of the two mains along Main Street was a
prerequisite to bringing service to our home at 98 Newberry Road.
Our letter of July 4, 1996 and MDC response of July 18, 1996 are enclosed.
I have spoken several times with Bob Laneri of the MDC. Bob has reviewed the
engineering for public water service on Newberry Road. He advises that extension of
service is unlikely for the following reasons:
1- South Windsor is not a member town of the MDC
2 - only two residences are currently excluded from public water service. (There are
residences with service available but not hooked up.)
3- Other land owners on Newberry Road will oppose our petition because of the
financial impact to them, frontage fees.
I l�st:spoke with:Bob on:December 5 `1996. 'He advised that although South Windsor
was not a member,town of the MDC support'fromyouur office would still be influential in
gaining public water service. Bob also advised that he would 1)canvas the neighboring
PPPPPPP-
landowners to identify who would want public water service on Newberry Road and 2)
determine if construction could be completed for the benefit of the MDC either in "closing
the loop" or replacing the "unconventional" service available to several residences to the
east of us.
I would be happy to meet with you to discuss our situation in more detail to offer clarity.
In addition to your support of our petition to the MDC, I would like to know what other
remedies the Town will support to provide quality water service to our home.
Thank you.
Sincerely,
Judith Sutton

Dear Mr. Alvarado
My wife and I petitioned the MDC in 1987 to extend existing water lines on Newberry
Road in South Windsor approximately 1,000 feet to service our home. This petition was
submitted shortly after the house was constructed. MDC turned down the petition on the
basis that South Windsor was not a "member town" but suggested that done properly,we
could arrange to have the lines extended by a contractor. In this scenario the Suttons
would be responsible for collecting any "frontage" fees from neighbors who would also
benefit from the extended water line.
The purpose of this letter is twofold. First, I would like to repetition MDC to extend the
water line. Secondly, I want to inform MDC that through their actions they are harming
me by unfairly increasing the cost to me of having the water lines extended. The water
line can be extended either east from the end of the Newberry Road pipe or west from
Main Street.
Regarding the first purpose. I understand that our two adjacent neighbors,the Thibaults
at 120 Newberry Road and the Andersons at Lot 1 would also like service form MDC.
Additionally, MDC previously indicated that they would prefer to extend the Newberry
Road pipe to Main Street to eliminate the "dead end" on Newberry Road.
Regarding the second purpose, informing MDC that its actions are harming me, I would
like MDC to consider the following.
MDC is allowing several houses east of us on Newberry Road to have "non
standard" connections to MDC. By this I mean that several houses that do not
have water lines 'officially" piped to them are connected to a single house "up the
Road" which is serviced by MDC. By allowing this to happen, water service is
extended but the water lines are not. The homes involved have no reason to
contribute financially to extending the water line properly. Had the lines been
PPPPPP,-
extended properly to service these customers an extension of only 300 feet
westward would be required to provide service to us.
MDC when it recently repiped its water lines on Main Street it did not extend its
lines around the corner lot. Usually the owner of a corner lot must pay frontage
on both Roads. By allowing the owner of the corner lots at the intersection of
Newberry Road and Main Street to have MDC service but not have pipes on both
frontages,MDC has made it effectively impossible to recover costs of extending
the pipes past these properties. MDC was made aware via our petition and phone
calls that we wanted water but appears to have ignored us in this construction
project. If the water lines had been extended to the end of the corner lots only a
small extension of 300 feet or so would have been required.
In summary, I would very much like MDC to extend service to our home at 98 Newberry
Road because of the poor quality of our well water. My wife and I would be pleased to
pay the frontage charges. If that is impossible, we would like MDC to stop its actions that
are harming us from contracting to have water lines extended. By this I mean that if MDC
will not extend service it should stop service to the non standard houses and complete the
construction work that should have been done at the intersection of Main and Newberry
Road.
I would like to thank you for your consideration in this matter.

Public Hearing on
Proposed Water Main
Extension
TO ALL PROPERTY OWNERS :
The Water Bureau of The Metropolitan District will hold a public
hearing in the Council Chambers of the South Windsor Town Hall, 1540
Sullivan Avenue, South Windsor on Tuesday, April 27, 1993, at 7 : 00
P.M. for the purpose of considering an extension of a water main in a
portion of MAIN STREET, South Windsor, from House No. 840 northerly
about 1, 460 feet to Newberry Road.
We would appreciate your attendance at the public hearing.
Should you be unable to attend the hearing, we invite any written
comments you may wish to make relative to the project, prior to the
hearing, in order for the District to make a decision based on as much
public input as possible.
Enclosed for your information and records is a copy of the list
showing the estimated assessment for your property.
If the proposed project were approved, then approximately two
months following the completion of construction of the water main,
assessments on owners served by the new mains would be declared due
and payable. At that time, an owner would have the option of
selecting either of two methods of payment: the District' s
installment method, or payment in full .
Under the installment method, an owner may pay his or her
assessment plus an interest charge of six percent per annum in sixteen
(16) equal installments over a fifteen (15) year period, or the owner
may pay his or her assessment in full within sixty (60) days of
billing and thus avoid payment of interest charges . If an owner fails
to make his or her payments on or before the final date due, he or she
is charged a fifteen percent (150) interest fee.
Should you have any questions concerning the proposed sewer
project or the upcoming hearing, please feel free to contact the
undersigned.

Public Hearing on Proposed
Water Main Extension
To All Property Owners:
The Water Bureau of The Metropolitan District will hold a
public hearing in the Council Chambers of the South Windsor Town
Hall, 1540 Sullivan Avenue, South Windsor, on Tuesday, July 16, 1991
at 7: OO P.M. for the purpose of considering considering an extension
of a Water Main in North King Street, South Windsor, from Main Street
easterly and southerly to Connecticut I-291.
We would appreciate your attendance at the public hearing.
Should you be unable to attend the hearing, we invite any written
comments you may wish to make relative to the project, prior to the
hearing, in order for the District to make a decision based on as
much public input as possible.
A copy of the list showing the estimated assessment for your
property is enclosed for your information.
If the proposed project were approved, then approximately
two inonths following completion of construction of the water main,
assessments on owners served by the new main would be declared due
and payable. At that time, owners would have the option of selecting
either of two methods of payment: the District' s installment method,
or payment in full.
Under the installment method, an owner may pay- his or her
assessment plus an interest charge of six percent per annum in
sixteen equal installments over a fifteen (15) year period, or the
owner may pay his or her assessment in full within 60 days of billing
and thus avoid payment of interest charges. If an owner fails to
make his or her payments on the final date due, he or she is charged
a 15 percent interest fee.
Should you have any questions concerning the: proposed sewer
project or the upcoming hearing, please feel free to contact the
undersigned.

Dear Mr. Gantick:
On January 1, 1989, the District will institute a new policy and
procedure regarding the adjustment or relocation of its water or sewage
facilities made necessary by town/city construction projects.
The new procedure will involve the town/city entering into a written
agreement with the District for each construction project it undertakes that
will require adjustments to District facilities costing in excess of $5000. A
copy of the standard agreement form is enclosed.
The major change in policy is that the District will estimate the
cost of the adjustment expense and state it in the Estimate of Cost (Part B)
of the agreement. This estimate of cost will be considered an upset price.
As long as the scope of the work. does not change significantly, the District's
charges will not exceed the original estimate.
Other things remain largely unchanged under the revised policy. The
District will do the planning, engineering, (including preparation of plans
and specifications), and inspecting for all adjustments or relocations of its
facilities. In addition, it will determine which portion of the work will be
installed by District forces and which portion will be installed by the
town/city or its contractor. In general, work done by District forces will be
limited to that which involves connecting to in-service water mains. The
town/city shall, at its cost, have the remaining adjustment work as stated in
Estimate of Cost (Part A) of the agreement, performed to District plans and
specifications.
I ri
-2-
Significant changes in the scope of adjustment work will be
undertaken only after a written change order modifying the agreement has been
executed. The town/city will be responsible for payment of the cost of such
additional work.
This policy is being instituted to provide better control of this
type of work by both the District and the town. Moreover, we mean it to
improve relations by avoiding misunderstandings and unanticipated costs. The
town/city will know in advance the maximum amount to budget for District
facility adjustments. In addition, the work, and responsibility therefore,
will be clearly defined.
Please contact Tip Garritt, Manager of Special Engineering Projects,
at 278-7850 extension 438 if you have any questions concerning these changes.

THE WEST HARTFORD AND RESERVOIR SIX
WATER PURIFICATION SYSTEM
of
THE METROPOLITAN DISTRICT
of
HARTFORD, CONNECTI CUT
This description of the purification works was written
especially for the use of non-technical readers, but
contains the same data that are available for profes-
sional use.
THE WATER PURIFICATION SYSTEM
of
THE METROPOLITAN DISTRICT
of
HARTFORD, CONNECTICUT
NATURAL PURIFICATION
The purity of rain water, which is the primary source of all public water
supplies, is changed the moment raindrops touch the soil . The rain water starts
' immediately to dissolve chemicals present in the soil and at the same time picks up
numerous bacteria. Fortunately, great numbers of these bacteria are harmless, _
but there is always the possibility that bacteria which may cause diseases, such as
typhoid, dysentery and cholera, will be present. The type and the amount of chem-
icals dissolved by the rain water generally have little direct effect on health,
but they do cause nuisances such as tastes, odors and discolorations.
Nature immediately lends a hand and starts to remove or change the char-
acter of the contaminating materials. As the water flows along a rivulet, a brook,
or a. river, it falls and splashes and comes into intimate contact with the oxygen
of the air. The oxygen. kills large numbers of bacteria, but not all of them by any
means. Some of the chemicals are changed in character, but very few are removed
entirely. There is often heard the expression that f"l o,.-ring water purifies itself
in some mystical distance. That is a very erroneous belief! True enough, nature
assists in the purification process, but it does not always render water safe
enough for human consumption.
ALGAE CONTROL
The storage of water in a reservoir for many months is another natural
purification process. During the period that water rests in a reservoir a large
portion of the particles suspended in the water settles to the bottom. Exposure
to sunlight and air removes great numbers of bacteria and also reduces the mater-
ials which discolor water. However, the very factors that aid in this purification --
sunlight and stillness -- also encourage the growth of algae, simple plants which
impart tastes to the water and- turn it cloudy. To control this growth, the water
in the reservoirs is tested frequently, and when the algae concentration becomes
excessiVe the reservoirs are treated with copper sulfate. The dose of copper
sulfate rarely exceeds 4 of one part in a million parts of water.
Sad to say, man frequently finds it necessary to dump all sorts of waste
products both human and industrial , into streams which eventually find their way
into public water supply reservoirs. Steps are taken to prevent, or reduce the
effect of such actions by inspection and close regulation of the habits of people
residing on land which drains into a reservoir. However, these regulations cannot
insure for certainty that dangerous contamination will not some day enter a public
water supply, thus making it necessary to have water purification plants which will
produce water of unquestioned purity at all times.
2.
FILTRATION AT THE WEST HARTFORD PLANT
One water purification system of The Metropolitan District of Hartford
is located in West Hartford, Connecticut, west of Reservoir No. 19 off Farmington
Avenue. Its main component parts are an aerator, sand filters, and machines for
applying chlorine gas, fluorides and chemical compounds which reduce the tendency
of the water to corrode metals.
AERATION
The aerator is the first device used in the purification process.. Water
from Nepaug_ Reservoir, the Barkhamsted Reservoir, or the system of small reservoirs
in West Hartford, can be made to flow directly by gravity to the aerator. Many
people, unfamiliar with the word "aerator", call it a fountain, and that describes
it very well . At the bottom of an open, circular, concrete chamber are some large
pipes with holes drilled in the top of them. The pressure of the water flowing
from any one of .the reservoirs, which are all higher than the aerator, causes
the water to shoot upward through these holes in a-spraylike effect. From the rim-
of the concrete basin, additional water is sprayed toward the center. . The water
failing to the bottom of the basin flows through the open joints of brick walls
into a cast iron pipe which delivers it to the sand filters. The capacity of the
aerator is 27 million gallons of water in a 24-hour day.
The purpose of the aerator is to cause oxygen from the air to enter the
water. As the water is sprayed upward and later falls downward, it separates into
. small particles, allowing the air to come into contact with a large portion of it.
This induces the oxygen of the air to dissolve in the water. It is essential to
have some oxygen in the water to improve' its taste. Water containing no oxygen
is flat tasting, similar to water which has remained in a drinking glass for a
long time.
There is another purpose of the aerator. Sometimes the water in a
reservoir picks up undesirable gases caused by the de.composition of the muds at
the bottom of a reservoir. One of these -gases, hydrogen sulfide, imparts un-
desirable tastes and odors to the water; another, carbon dioxide, forms rust in
pipes. At other times, algae release droplets of oil having strong tastes or
odors. By spraying water containing these gases or oils into the air_, they are
removed from the water to a large extent, improving its taste.
Aeration of water also affects its chemical content. Certain elements,
such as iron and manganese, will remain dissolved in eater containing a large
_amount of carbon dioxide and very little oxygen. By aeration, these elements are
changed to an insoluble' form', which means that they can be removed from the
water by filtering it through sand.
SLOW-SAND FILTRATION
The next step in the purification process is the filtration of the aerated
water through fine sand. The West Hartford plant of the Hartford Metropolitan
District is of the type known as a slow-sand filter. At present it is made up of
22 units, called filter beds, which can be operated separately to filter the water
flowing from the aerator. If necessary, the aerator can be bypassed and the water
•
from the reservoirs applied directly to the filters. With all 22 filter beds
in service, a total of 55 million gallons of water can be treated in 24 hours for
long periods of time and somewhat larger quantities can be filtered to take care
of peak .demands of short duration.
Of the 22 filter beds, 16 are 2 acre each and 6 are 3/4 acres each
for a combined total of 13 acres. Each bed has side walls 12 feet high.
On the floor of the filter is a network of glazed tile or concrete pipes all
terminating in a central conduit, which extends through one of the vertical
concrete side walls, and is connected to a cast iron pipe fitted with control
valves. The, p•ipes in the underdrainage network have small openings in their
walls to allow the entry of water.
Over the underdrainage system and the floor of the filter is a layer of
stones 12 inches in depth. The stones, which are about 2 inches in size immediate-
ly over the pipes are graded so that at the top of the layer, the "stones" are
only 1/8 of an inch ' in diameter. Over the stones- is sand to a depth _of 27 inches.
This sand is a special quartz sand with particles especially graded in size and
averaging about 1/75th of an inch in diameter.
On top of the sand is the water which has passed through, or bypassed,
the aerator. The depth is 6 feet and it is kept constant by large copper floats
which open and close valves that control the flow of water from the aerator to
the top of the sand.
The action of a filter is simple. The water over the sand gradually
seeps down through it and the underlying stones, until it enters the underdrain-
age system. From these pipes, it flows into the central conduit and then out of
the filter by means of a cast iron outlet pipe. A half-acre filter is generally
operated to deliver two million gallons of water in 24 hours. This is equivalent
to only a half-pint of water per minute from each square foot of the filter, �•rhich
explains the reason for the name of the process: slow-sand filtration. Slightly
higher rates can be obtained when the filter is clean and much lower rates when
it is dirty.
The flow of the water is controlled by means of a valve in the cast
iron outlet line. In the same line is a device known as a Venturi meter, which
measures the amount of water flowing through the cast iron line, and records the
value on a chart. The outlet line from each filter is joined to larger pipes into
which all the other twenty-one filter units connect. These larger pipes, of which
there are three at present, carry the filtered water to underground concrete
storage basins .that have a capacity of 15 million gallons of water when full .
Although the action of a filter unit is a simple process, the results are
quite remarkable. The sand removes- particles of dirt, leaves, twigs and fishes,
but what is more gratifying is the fact that bacteria, of which it takes about
25,000 laid end' to end to make an inch, are removed 'from the water as it passes
through the sand. Moreover, some of the chemicals which impart color to water are
also removed. The. iron and manganese compounds that were made to combine with
oxygen at the aerator are likewise taken from the water.
4.
STORAGE BASINS
There are two concrete basins for storing the filtered water before it
.flows to the city. One basin holds 6 million gallons of water and -the other, 9
million gallons. The people of the Hartford Metropolitan District now use on the
average almost 55 million gallons of water in one day, and sometimes as much as
80 million, so there is usually less than one-third days' supply of filtered water
on hand.
The rate at which.water -is used in The Metropolitan District is, however,
constantly changing during the course of the day. Since it is better to operate
the filter beds at a constant rate, the storage basins serve the very useful pur-
pose of making up the difference.
DISTRIBUTION SYSTEM
The water from the storage basins is carried to the cities .and towns of
The Metropolitan District by two cast iron pipe lines, 42 inches in diameter and
a concrete pipe 54 inches in diameter. A short distance below the West Hartford'
Filtration Plant, these large pipe lines branch out into other large pipe lines
and then into many smaller pipes that supply the individual streets of The Metro-
politan District. At various strategic points in the District are located several
tanks and storage basins which help to maintain the supply and pressure of the
water in the distribution system. Their combined storage capacity, when full , is
19.9 millions of gallons.
CHLORINATION
At points just downstream from the filters and immediately ahead of the
basins,, a solution of chlorine gas in a small amount of water is injected contin-
uously into the large volume of water flowing through the pipes. Chlorine is a
chemical that destroys bacteria very readily. There are some bacteria that manage
to get through the sand of the filters, and since it is possible that some of these
might be disease-producing organisms, all precautions must be. taken to insure that
the water delivered to a population of 390,000 is absolutely safe, and chlorine is
the element that furnishes this safeguard.
The amount of chlorine added to the water is minute; about ten pounds to
a million gallons of water, which weigh 8,340,000 pounds. Yet this small con-
centration of chlorine is very effective in destroying bacteria, as is known from
laboratory tests made every day. Four special machines are employed to pump the
chlorine solution into the water, three of them are in constant use and the fourth
is an emergency reserve unit. The machines are so constructed that they will
inject chlorine in direct proportion to the flow of water through the pipes.
A constant check is kept on the chlorine content of the water by three
automatic analyzers which measure the concentrAt-ion of the chlorine as the water
.enters the storage basins, record the results on a chart, and transmit the instan-
taneous readings to the control room.
_ r
SAND WASHING
This completes the purification process as such, but a large amount of
work is necessary to keep the-process going. In the course of time, the top of the
sand in the filter beds becomes entirely clogged with the materials removed from
the water. When this happens, very little water can be passed through the filter,
even though the valve on the outlet pipe is opened wide. Gauges known as "Loss of
Hbad Gauges" indicate when this condition is being approached. The remedy is to
wash away the film of "dirt" on top of the sand and thereby allow the water to
` pass through the sand again. To do this, the water over the sand is drawn down
to a depth of 8 to 10 inches and a spring tooth harrow, such as a farmer might
use, is dragged over the 2 acre or 3/4 acre of sand by means of a tractor. At the
same time, the water over the sand surface is made to flow horizontally. The
tractor and the harrow stir up the sand and dislodge the dirt particles from the
sand grains and this dirt remains in suspension in the water. The horizontal
flow of water, created by letting in clear water at one side of the filter and
drawing it off on the opposite side of the filter, . carries away the suspended
dirt to a sewer.
The sand is cleaned sufficiently well by this washing process so that a
filter .can be returned to service and again filter approximately 90 millions of
gallons before it needs to be washed once more. The volume filtered varies with
the amount of contamination in the water and the rate at which it is filtered.
Generally any one filter will last six to eight weeks between washings.
This washing process has its limitations, it washes only the top foot
of sand. The lower layers of sand gradually become coated with the same type of
"dirt"• as covered the top before washing, and the sand is now densely packed and
offers considerable resistance to the flow of water. After approximately 3
billions of gallons of water have passed through a filter in the course of about
6 years, it is necessary to wash all of the sand, from top to bottom. This is
done by a method known at this plant as "reconditioning." Washing and replacing
the sand is considerably cheaper than removing the dirty sand and replacing it
with new clean sand.
The reconditioning process is carried on by shoveling all the sand
overlying the surface of the stone into hoppers, erhere a stream of water flowing
at high velocity picks. it up and carries it along lines of three-inch rubber
hose to. another type of sand washing machine known as - a separator. The separator
is a closed steel tank, three feet in diameter and six feet high, the lower half
being cone shaped. Near the top of the separator is a connection for the end of
the three-inch rubber hose line, which brings the.mixture of dirty sand and
water from the hoppers. A battery of six hoppers and six separators is used at
one time. The sand and water mixture enters a separator with a high velocity
and strikes a steel plate inside the separator. The impact knocks the dirt from
the sand grains, the heavy sand sinks into the cone shaped part of the machine,
and the dirt flows out of the separator through a pipe at its top. The clean
sand is drawn from the cone and replaced over the stone to a depth of 27 inches.

FLUORIDATION
In 1960 The Metropolitan District began the practice of adding one part
per million of fluoride to the water in order to provide the benefits that
children's teeth derive from drinking water which contains this small amount of
the fluorine element. The fluoride is applied to the water in the form of a pow-
der known as sodium silicof.luoride. The application is by three machines which
automatically and continuously weigh the required amount, put it into a small
amount of water, stir it until dissolved, then discharge it into the main stream
of water flowing in three large pipes, just after filtration and before storage
in the two concrete basins.
A constant check is kept on the concentration of fluoride in the water
as it enters the storage basins with another automatic analyzer which tests for
fluorides continuously and records the results on a chart.
Fluoride compounds in large -conceritrations are poisonous so the oper-
ators 'are required to wear respirators and rubber clothing arhen they load the
hoppers of the machines. - Dust collectors are provided on all the machines to
reduce the hazards.
CORROSION CONTROL
The people of The Metropolitan District enjoy a very -soft and pure
water, but because it is so soft it also tends to be corrosive. That .means it
will dissolve minute quantities of copper from brass or cooper pipes and iron
from pipes that have that element in their composition. If the piping system is
made up of a mixture of metals, or if the temperature of the water is too high,
the rate of solution is greatly accelerated. The corrosion products are a nuisance
in that they discolor the water and plumbing fixtures and in that they weaken the
pipe walls, roughen the interior surface, and impede the flow of water.
These undesirable effects can be eliminated by adding a small amount of
other harmless chemicals which neutralize the corrosive nature of the water. At
this plant lime is used to protect the pipes which have a copper composition and
a complex compound known as sodium hexa-meta-phosphate is used to protect pipes
with an iron composition.
The lime is added to the water by automatic weighing machines in very
much the same manner as the fluorides. The application of the sodium hexa-meta-
phosphate is slightly different in that a solution of known strength is made up by
the operator and .then small diaphragm p unps force the solution into the three large
pipes which carry filtered water to the 6- and 9-million gallon storage basins.
The lime dose is approximately 6 parts per million which is equivalent to 50
pounds per million gallons , and the sodium hexa-meta-phosphate is at the rate of
one part per million, or 8-1/3 pounds per million gallons. These dosage rates are
varied when laboratory tests indicate the need for a change. Automatic recording
analyzers indicate the effect of the lime on the water.
It is between filtration and storage that the chlorine, fluoride,
phosphate and caustic soda are added. The last mentioned chemicals, phosphate
and caustic soda are used for the prevention of metal .corrosion.
Water, which is now conditioned for drinking, i's conveyed to the
consumers by means of two 54-inch diameter mains. The depth of the 10
million gallon storage basin fluctuates according to demand under the watchful
eye of the plant operator who is ever ready to replenish the sparkling supply.
SLUDGE DECANTING AND DRYING
Material which has settled in the coagulation basin, together with
the dirty wash water, is directed to the decanting basin. Here the heavy
particles are again settled and concentrated on the bottom. The clear water
above is chlorinated and pumped back into Reservoir 6 after which the sludge
is drained onto one of two drying beds. Following a four or five day period
the material is removed as a cake to be disposed of as land fill .
• LABORATORY CONTROL
Two well-equipped laboratories, licensed by the Connecticut State
Health Department, are maintained, one at each filter plant. Daily bacterio-
logical tests are made on the water flowing to the treatment plants , at .various
points in the plant; after chlorination, and on water collected from n�uurcrous
points throughout the distribution system. Microscopic examinations to deter-
mine the kind and ntanber of algae present in the reservoirs are made acckly.
Various chemical and physical tests are made on samples from the reservoirs ,
the treatment plants and the distribution system. These bacteriological tests
show that the water produced at the treatment plants. of The Hartford Metropolit-an
District is of excellent character, meeting the rigid requirements of the
United States and the Connecticut State Health Department.

TO ALL PROPERTY OWNERS:
The Metropolitan District has received your petition for a water main to serve your property. I
understand by your letter of June 29, 1992 that you are waiving your rights to a public hearing and that
you agree to pay the front footage assessment for this improvement to your property.
Attached for your information and records is a list of the assessments to be levied against the
properties involved in this project. As stated in the assessment list, these assessments are based on the
schedule of rates adopted November 19, 1991 and effective January 1, 1992 at $39.00 per front foot or
adjusted front foot.
The terms of payment of water main assessments are provided by ordinance of The Metropolitan
District, and are as follows:
Approximately two months after the completion of installation of a main water pipe, assessments
on owners served by the new mains are declared due and payable. An owner may select either of two
methods of payment: the District's installment method, or payment in full.
Under the installment method, an owner may pay his assessment plus an interest charge of six
percent per annum in sixteen (16) equal installments over a fifteen (15) year period, or the owner may
pay his assessment in full within sixty (60) days of billing and thus avoid payment of interest charges.
If an owner fails to make his payments on or before the final date due, he is charged a fifteen percent
(15%) interest fee.
Please acknowledge receipt of this letter and the accompanying information by signing the
enclosed copy of this letter and returning it to The Metropolitan District.
Sincerely,
3 4 Robert A. Hagan
