RE: Lilliwaup Trust(Parcel#32319-24-00000)Evaluation of Failure
Dear Inspector:
Attached is a replacement septic design for the caretaker's house at a large acreage property located at 501 N
Lilliwaup St,Lilliwaup.There is an existing 2-bedroom home built in 1945 that ties into a gravity septic
system with no documentation/septic records. There is an existing 900-gallon single-compartment septic
tank followed by a gravity drainfield of unknown size and location.
The system was discovered to be failing at a recent service. The drainfield is no longer taking water,with
solids and effluent returning while pumping. The owner has been experiencing issues and has decided to
move forward with an upgrade to a modem system.
The existing septic tank is to be decommissioned or removed and the old drainfield is to be abandoned.
There is limited space available because of very steep slopes on this property. A new curtain drain is
proposed behind the house,garage and up-slope of the new drainfield area because of wet season runoff that
causes drainage issues for the property.
We are proposing a new 1,000-gallon 2-compartment septic tank with risers and lids to the surface and an
effluent filter followed by a new 1,000 gallon minimum pump chamber is to be added. The new drainfield is
required to be 400 s.f of shallow press=trench using an application rate of 0.6. 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 non-compliant repair with 12"+vertical separation. The drainfield
meets 100'+setback to surface water and wells.
The property owner's representatives contact information is as follows:
