The drainfield sustained major damage when it was rototilled by the landscaper and had to be replaced in early 2023. It turned out that the soil structure was too damaged and along with a chronic running toilet,the area became saturated again. The existing pre-trash tank,NuWater pretreatment tank,and 1,000-gallon pump tank will continue to be utilized. The old drainfield is to be abandoned in place and a new shallow pressure trench drainfield is to be installed up behind the house. The new drainfield consists of 600 s.f.of shallow pressure trench using an application rate of 0.6. - The system will also continue to use a control panel including timed dosing,a counter and elapse meter to prevent overuse and facilitate ongoing operation and maintenance. This is a compliant repair with 12"+ vertical separation and Treatment Level B. The drainfield meets 100'+setback to surface water and wells and we have also designated a full reserve drainfield area.

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. Encase all water lines within 10' of drainfield 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. 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 OpMpi t ' ce on your NuWater pretreatment system.
