There is an existing 3-bedroom home built in 1936 that ties into a gravity septic system installed in 1978- The existing system has a 1,200-gallon 2-compartment concrete septic tank followed by a gravity loop drainfield. The owner has been having some issues with the septic for several years,and the drainfield is not taking water properly.The existing tank may be reused if the installer determines that it is in acceptable condition. The tank must be water-tight,have an effluent filter and risers/lids to surface. If it cannot meet these requirements,the tank is to be decommissioned or removed and replaced with a new 1,200 gallon 2- compartment septic tank. The old drainfield is to be abandoned in place. We are proposing the addition of a new 1,000-gallon pump chamber. The proposed new drainfield is in a high-and-dry location and consists of 450 s.f of sand-lined pressure bed using an application rate of 0.8.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. The drainfield is over 50' from wells and over 100' to the Skokomish River. We have also designated a 450 s.f.reserve drainfield area. In compliance with the Table IX repair guidelines,this system meets Treatment Level B with pressure distribution and timed dosing. The property owner's contact information is as follows: Peggy Mitchell 3311 E State Rte 106 Union,WA 98592 (360)229-0891 If you need further information,please contact my office at(360)899-2255.
