Revised:4/14/2025 Arrow Septic Designs, Inc 171 E.Vuecrest Dr. Union,WA 98592 June 26, 2025 Mason County Department of Health Services 415N6thSt Shelton,WA 98584 RE: James &Christine Moser(Parcel#22018-50-00040) Evaluation of Failure Dear Inspector: Attached is a replacement septic design for a property located at 210 E Pickering Dr, Shelton,WA 98584. There is an existing 2-bedroom home built in 1967 that ties into a 2-bedroom permitted gravity septic system of the same era. The existing system has a 1,000 gallon single-compartment concrete septic tank followed by a d-box and 339-360 s.f.gravity trench drainfield. The septic system was recently inspected because the owners have had trouble with slow drainage. During the inspection, it was found that the drainfield is flooded and is not accepting water, and upon pumping down,there was water returning to the tank. The new drainfield will be approximately 68 ft from Little Twin Lake and soils are Type 3, requiring treatment level B& BL2 so we are proposing a NuWater BNR-500. The existing septic tank may be used for a pre-trash tank if the installer deems it to be in acceptable condition, or it may be decommissioned or removed. The NuWater will be followed by a new 1,000-gallon minimum pump chamber. The new drainfield consists of 300 s.f. of shallow 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. This replacement system meets Table X guidelines with over 50' (approx. 68 ft to the lake edge), Treatment Level B &BL2, and 12"+ of vertical separation. We have designated a full reserve drainfield area.

Install Laterals with contour of the ground. 2. Install trench bottoms 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 at distal end of each lateral in drainfield with bottom extending to the drainrock/native soil interface. Glue "T"to bottom so Observation Port cannot be easily removed from ground. Install removable cap on top of port at final grade level. 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 not required. 8. Install check valve in pump outlet line to prevent system from draining back into the pump chamber. 9. 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, turn orifices down (6 o'clock) and glue laterals to manifold. Orifice shields may be used with orifices in the 12 o'clock position in lieu of turning the orifices down to the 6 o'clock position. 10. 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. 11. Waterlines must be a minimum of 10' to any tank or drainfield (a reduction to 5' may be obtained with a State waiver on lots that meet minimum lot size). Encase all water lines within 10' of septic transport lines and under any driveway/parking areas. 12. Divert all storm water runoff away from on-site sewage system. 13. No curtain drains allowed within 10' of the up-slope edge or 30' of the down-slope edge of the drainfield and reserve area. 14.No vehicular traffic over drainfield area or tanks. 15. Inspect floats, clean filters, and test high water level alarm every 6-12 months as needed. 16. All materials and workmanship must meet County and State regulations. 17. Deviation from this design without prior approval from the Designer and Mason County Environmental Health Department will make this design null and void. 18. All manhole lids and access, sampling or inspection ports must have locking covers and be located at ground level. 19. All pressure systems with a pump chamber outlet higher than the drainfield must have an anti-siphon valve or a 1/8" hole drilled in the discharge pipe above the pump to prevent siphoning. Ensure anti-siphon hole sprays down/away from tank opening. 20. All transport lines under driveways or parking areas must be encased to prevent crushing. 21. Homeowner is responsible for all property lines and easements. 22. Please Note: When you begin using your septic system, contact your septic installer to discuss setting up a schedule for your required er Maintenance on your NuWater pretreatment system.
