RE: Joseph Maulden(Parcel#32127-50-00187)Evaluation of Failure
Dear inspector.
for a property located at 41 E Lambeth Way,Shelton.There is an
Attached is a replacement septic design
at ties into a gravity septic system of the same era-. There is a
existing 3-bedroom home built in 1979 th
existing 1,200-gallon 2-compartment septic tank followed by 150 LF of gravity trench drainfield.
The system was discovered to be failing at a recent service. The drainfield is no longer taking water,likely
because the old drainfield was installed too deep and sits on the restrictive layer. The back yard slopes up
away from the house so the gravity drainfield was installed deep. The owner has been experiencing issues
and has decided to move forward with an upgrade to a modem system.
The existing 1,200-gallon 2-compartment tank can be reused if the installer verifies it is in good condition
and must be retrofitted with an effluent filter. A new 1,000 gallon minimum pump chamber is to be added,
but it is recommended to oversize the tank to a 1,200 or 1,500 for extra surge capacity because of the number
of occupants. The old drainfield is to be abandoned. The new drainfield is required to be 600 s.f.of shallow
pressure trench using an application rate of 0.6 but we have oversized it to 720 s.L.The system will also have
a control panel including timed dosing,a counter and elapse meter to prevent overuse and facilitate ongoing
operation and maintenance. This is a noncompliant repair with 12"+vertical separation. The drainfield
meets 100'+setback to surface water and wells.
The property owner's contact information is as follows:
