There is an existing home built in 2005 that ties into a gravity septic system from 1990. The existing system has a 1,000-gallon 2-compartment concrete septic tank followed by a gravity loop drainfield. The owner recently serviced the system and got a deficient report,and it was discovered that the drainfield is not taking water properly. The owner has been having ongoing issues with the septic and this part-time use home is soon going to be their full-time residence,so they decided to move forward with a replacement septic system. Because of its age,the old drainfield will be abandoned and because it has already been repaired previously,the old tank is to be decommissioned or removed. We are proposing a new 1,000 gallon minimum 2-compartment septic tank with risers and lids to the surface and an effluent filter. The septic tank will be followed by a new 1,000-gallon pump chamber. The new drainfield consists of 400+s.f. of shallow pressure bed 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 I2"+vertical separation. There are no surface water or well setback issues.
