RE: Peggy Mitchell(Parcel 1l32106-33-00160)Evaluation of Failure
Dear Inspector:
Attached is a repair septic design for a property located at 3311 E State Rte 106,Union,WA 98592. 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:

2. Install bed bottom level.
3. Install locator tape or rebar at each end of all drainfield laterals.
4. Install observation ports as indicated on the plot plan. One required in each comer of the
bed. Two with bottom extending to the bottom of the drainrock and two extending to the
sand/native soil interface. Glue"1"to bottom so Observation Port cannot
eerily

5. Install drainfield during dry weather and soil conditions; any soil smearing must be
eliminated by hand raking.
6. Install threaded clean-outs at the end of all laterals(cap must extend to within six inches
of finished grade and be marked with locator tape or rebar).
7. Install audio/visual high water level alarm. Redundant off switch required.
8. Install 1/8"mesh noncorrosive pump screen(min 12 sq. ft, surface area,not to interfere
with controls or floats.) Or pump screen may be substituted with Bio-Tube in septic tank.
Pull bio-tube every 6-12 months and flush back into tank.
9. install check valve in pump outlet line to prevent system from draining back into the
pump chamber.
10. Tee to Tee construction between laterals and manifold with orifices oriented at 6 o'clock.
Install laterals to the manifold with the orifices at 12 o'clock,(do not glue),after pressure
test and Environmental Health Dept.approval, rum orificcs down(6 o'clock)aad glue

11. Filter fabric required over drain rock prior to back filling. If the drain rock extends above
natural grade,run the filter fabric at least 2 inches down the trench wall.
12. Encase all water lines within I C' of drainfield and under any driveway/parking areas.
13. Divert all storm water runoff away from on-site sewage system.
14. No curtain drains allowed within 10' of the up-slope edge or 30' of the down-slope edge
of the drainfield and reserve area.
15. Have the septic tank and pump chamber pumped or inspected every 3 to 5 years.
16.No vehicular traffic over drainfield area
17. Inspect floats,clean filters, and test high water level alarm every 6-12 months as needed.
18. All materials and workmanship most meet County and State regulations.
19. Deviation from this design without prior approval from the Designer and Mason County
Environmental Health Department will make this design null and void.
20. All manhole lids and access,sampling or inspection ports must have locking covers and
be located at ground level.
21. All pressure systems with a pump chamber oudei higher than the drainfield must have a
1/8"hole drilled in the discharge pipe above the pump to prevent siphoning.
22. All transport lines under driveways or parking areas must be encased to prevent crushing.
23.Homeowner is responsible for all property lines.
