RE: Equestrian Drive, Lot #25 A,
Sanitary Disposal System
Dear Mrs. Oliver:
This office is in receipt of a print of our Septic System Design
.Plan on July 17, 1987. We have reviewed the As Built conditions
you have submitted to us, and note that the existing house
foundation was installed with a top of foundation wall elevation
approximately equal to 111.50 feet. The bottom of the Sanitary
Disposal System was designed to be at an elevation of 112.00
feet, resulting in an elevation at the foundation of
approximately 115.21 feet.. The pipes in the system were designed
at minimum pitch. This provides you with the lowest elevation
at the house which would be met in order for the system to flow
by gravity. Since the top of your foundation is lower than
the invert elevation as designed at the foundation wall, you
must redesign the system to include a pump chamber, which would
then pump the effluent from a lower elevation to the leach
trenches which are at an elevation of approximately 114.33 feet.
This office is prepared to furnish you with a revised design
of this system. We ask that you furnish us with a Certified
Foundation Plan showing the exact location of your foundation
on the ground with a Certification to the exact elevation of
the top of the foundation. Our fee for revising the Sanitary'
System Plan to include the pump station shall be $400.00, payable
in advance.
If this arrangement meets with your_ approval, kindly sign this
letter in the appropriate location and return it to our office.
We will require three weeks from the time we receive your letter
