RE: Chris&Pain Murphy(Parcel#31901-13-90220)Evaluation of Failure
Dear Inspector:
Attached is a repair septic design for a property located at 128 SE Driftwood Ln, Shelton,WA 98584.There
is an existing 2-bedroom house that ties into a gravity septic system installed in 1987. The existing system
has a 1,200-gallon 2-compartment septic tank followed by a 240 s.f.gravity drainfield.
The owner has been having issues with the septic and it was found that the drainfield is not taking water the
way it should. Upon further investigation, it was discovered that the drainfield is clogged with roots,
saturated and was not originally installed level.
The existing 1,200-gallon 2-compartment septic tank may be kept/re-used and must be retrofitted with an
effluent filter. The new drainfield consists of a new 10' x 30' gravity bed,for a total of 300 s.f.. This is a
compliant repair with 36"+of vertical separation. There are no surface water or well setback issues.
The property owner's contact information is as follows:
Chris&Pam Murphy
128 SE Driftwood Ln
Shelton,WA 98584
(360)490-5559
If you need further information,please contact my office at(360)898-2255.
