There is an existing 2-bedroom home built in 1978 that ties into a gravity trench septic system of the same era. The existing system has a 1,000-gallon septic tank followed by a 300 s.f. gravity loop drainfield. The septic system has been having issues with slow drainage. Upon further investigation, it was found the drainfield was matted with roots and saturated. The owner has decided to move forward with a replacement septic system. Because of its age,the existing 1,000-gallon septic tank should be decommissioned or removed and the old drainfield will be abandoned. We are proposing a new 1,000-gallon 2-compartment septic tank with risers and lids to the surface and an effluent filter. It will be followed by a new 1,000-gallon pump chamber. The new drainfield consists of 400+s.f. of shallow pressure trenches 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"+of vertical separation. There are no surface water or well setback issues and we have designated a full reserve drainfield area. The property owner's contact information is as follows: Keith Fuller PO Box 714 Shelton,WA 98584 (360)490-3811 If you need further information, please contact my office at(360) 898-2255.
