There is an existing 2-bedroom septic system that the records show was installed in 2008. The existing system has a 1,200-gallon 2-compartment septic tank with an effluent filter and the existing gravity loop drainfield is 10' wide x 24' long,for a total of 240 s.f.. The system has been used for many years with a park-model trailer. The new owners are planning to install a new 3-bedroom manufactured home. A current Operation& Maintenance inspection of the existing septic will be performed soon. In order to increase the septic size from a 2-bedroom to a 3-bedroom,we will add another equally sized bed of 10' wide x 24' long,or 240 s.f..,effectively up-sizing the whole drainfield to 480 s.f.total(450 s.f. required with 0.8 app rate). A flow-splitter or 3`d D-box will be needed to ensure equal flow to both beds. This is a compliant upgrade with 36"+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: Zenith Group NW,LLC P.O. Box 1708 Rochester, WA 98579 Derek Johnson(253)225-2808 If you need further information,please contact my office at(360) 898-2255.
