There is an existing 1,000-gallon single-comparhnent septic tank followed by 160 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 of the high water table. The owner has decided to move forward with an upgrade to a modem system. Proposed is a new 1,200 gallon operating capacity minimum 2-compartment septic tank with an effluent filter. The old tank can be re-used as a pump chamber if it is in acceptable condition. The old drainfield is to be abandoned. The new drainfield consists of 450 s.f.of shallow pressure trench using an application rate of O.S.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 and we have also designated a full reserve drainfield area. The property owner's contact information is as follows: Patsy Johnson 151 W Wivell Rd Shelton,WA 98584 (360)463-1587 If you need further information,please contact my office at(360)898-2255.
