The existing 3-bedroom septic system was installed in 1991 and consists of a 1,200 gallon 2-compartment Fred Hill septic tank followed by a 10' x 36'(360 s.f.total)gravity dminfield. The owner would like to upgrade the septic to accommodate both the existing 3 bedroom home,but also the new/proposed I bedroom caretaker ADU. A pump cylinder with a solids pump will be used at the new ADU to send sewage into the existing septic tank. The existing 1,200 gallon 2-compartment tank is to be retrofitted with an effluent filter and risers/lids to the surface. The existing drainfield was camera scoped by Bamford Septic Repair to verify location and condition and the 3 existing drainfield lines are actually 32' long. We are proposing the addition of 2 more 32' gravity drainfield lines for a total of 480 sf of dminfield. The d-box will need to be replaced to pipe in the 5 total drainfield lines. The d-box is to include speed levelers to equalize flows and a cover to surface for ongoing operation and maintenance. This is a compliant upgrade with 36"vertical separation and a full drainfield reserve area of 600 s.f.has been designated. The property owner's contact information is as follows: Houston& Heather Gamer 51 NE Salty Dr. Belfair,WA 98528 (360)731-1433 Ifyou need further information,please contact my office at(360)898-2255.
