Dear Mr. Kelley:
Re: Lot 16 - Carriage Drive
An inspection of the sewage disposal system at the above
location disclosed that the system does not conform to
the design originally approved. It appears that the
sewage disposal system is in the ground water and not the
prescribed 18" above it.
It will be necessary to now pump the effluent from the
septic tank into a new leaching field placed 18" into the
filled area. You are advised to submit an engineering
plan to show the following design:
1. Place in series a new 750 - 1,000 gal. concrete
septic tank to serve as a pump chamber.
2. Install a sewage pump in this chamber with a mercury
float switch with 3 positions - 1) off; 2) on;
3) alarm; and a check valve.
3. Provide a distribution box with baffles.
4. Reinstall 225' of 3' wide trench at no greater depth
than 18" into the filled material.
5. Extend filled area a minimum of 15' beyond any portion
of the leaching system.
6. Set the pump to fill 75% of the pipe capacity in the
leaching field.-

I have had success with the Barnes Model SE 52 or the
Goulds WP 05125, single phase 220 volt pumps.
I have also used the Als#4-1 alarm box with bell and light
and the A1S2-3 mercury switch which are used with the
Goulds pump.
If you have any questions, or if I may be of any further
help, do not hesitate to call me.
Very truly yours,
TOWN OF SOUTH WINDSOR

MEMORANDUM July 20, 1978
To: J. E. Page, Town Engineer/Planner
Re: Lot 16 - Carriage Drive
Approval of a sewage disposal system designed by Emanuel Lucek dated
3/23/78 for the above lot was given by me on 5/3/78.
Although the ground water observations made by the design engineer
indicated water at 30" below ground level, the design was drawn to
assume a ground water elevation at 1' below ground level. Through
conversations with the builder and the design engineer, this assumed
ground water elevation was recommended by Mr. Daniel Sevino of the
State Health Dept. My approval of the plan was based on these
assumptions.
After installation of the sewage disposal system, it was determined
that the system was installed contrary to the approved design. This
now puts the system in violation of the Public Health Code in regard
to the required separating distances of the ground water table and
bottom of the leaching system.
In order to rectify this problem, the system would now have to be
re -installed at a higher elevation and a pumping arrangement installed
to meet the approved plan of design. It is the design engineers'
feeling that the system would not be in violation using his ground
water observations. This is true, but I feel my approval was based
on the assumption of a ground water table at a higher elevation.
As a solution to this problem, I offer the following steps to be taken:
1. Install a perforated stand pipe adjacent to the leaching system
to be used for future ground water observations.
2. Determine the ground water observations next spring between
February 1 and May 1.
3. Determine the elevation of the presently installed system.
4. Retain a certified check in the amount of $2500.00 for a new
sewage disposal system and pumping arrangement, if the present
system is found to be in violation next spring. (See letter 7/14/78)
5. All elevations are to be mutually agreed upon by the Town Engineer
and the design engineer. Final approval of the sewage system should
be withheld until the above conditions are met; however, I will
conditionally approve the installed system in order that a
certificate of occupancy may be issued.,
