The 2-bedroom home was replaced in 2022. The house was tied into the old existing gravity trench septic system at that time. The old system has a homemade 1,200-gallon septic tank followed by a 180 s.f. gravity drainfield. The septic system has been having issues with slow drainage. Upon further investigation, it was found the drainfield is saturated and no longer taking water. The owner has decided to move forward with a replacement septic system. Because of its age and because it is homemade,the existing 1,200-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 600 s.f.of shallow pressure trenches using a type 5 soil with an application rate of 0.4.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. The drainfield meets the setback of 100' to surface water and the existing well. We have designated a full reserve drainfield area. The property owner's contact information is as follows: Dave Hooker&Michele Garrett 5230 SE Arcadia Rd Shelton,WA 98584 (360)490-5407 If you need further information,please contact my office at(360)898-2255.
