There are no original septic records for the existing gravity trench septic. The existing 2-bedroom mobile home is to be removed and a new 2-bedroom cabin is to be built in its place. Since the number of bedrooms and flows are not changing but the new home will be more than 200 s.f. larger than the old one,this will be considered a low-impact expansion. Records indicate the existing system consists of a 1,000-gallon septic tank followed by approx. 85 lineal feet of gravity trench drainfield on the lake side of the house. Recent service records indicate that the tank has a high effluent level and the drainfield isn't taking water the way it should. The existing tank is to be decommissioned or removed and the old drainfield is to be abandoned. The new proposed 2-bedroom replacement system will include a new 1,000-gallon 2-compartment septic tank with effluent filter followed by a 1,000-gallon pump chamber. The proposed replacement drainfield is a 400 s.f. pressure trench on the up-hill side of the house over 100' from the lake. We are also proposing a new control panel with timer,elapse meter and event counter to extend the life of the system and to facilitate future operation and maintenance. The proposed septic system is compliant with the tanks being over 50 feet from the lake and the drainfield being over 100 feet to the lake and wells and 24"+vertical separation. We have also designated a full reserve drainfield area.

Install Laterals with contour of the ground. <_tcus IGNE'fl'_ 2. Install trench bottoms level. + 1 I 3. Install locator tape or rebar at each end of all drain,_field laterals. 4. Install observation ports as indicated on the plot plan. One required at distal end of each lateral in drainfield with bottom extenn;ng to the drsinrock/native soil interface. Glue "T"to bottom so Observation Port cannot be easily removed from ground Jns s11 ieulovable 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. 8. Install 1/8"mesh non-corrosive 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 ank. 9. Install anti-siphon valve above pnn^tp in pump chamber to prevent the pump chamber from siphoning into the drainfield. 10. Jnstall check valve in pump outlet line to prevent system from draining back into the pump chamber. 11. Tee to Tee construction between laterals and manifold with orifices oriented at 6 o'clock. Tnstall 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. 12.-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 wench wall. 13. Encase all water lines within 10' of drainfield and under any driveway/parking areas. 14. Divert all storm water runoff away from on-site sewage system. 15.No curtain drains allowed within 10' of the up-slope edge or 30' of the down-slope edge of the drainfield and reserve area. 16. Have the septic tank and pump cha;nber pumped or inspected every 3 to 5 years. 17.No vehicular traffic over drainfield area. 18.Inspect Moats, clean filters, and test high water level alarm every 6-12 months as needed. 19. All materials and workmanship must meet County and State regulations. 20. Deviation from this design without prior approval from the Designer and Mason County Environmental Health Department will make this design null and void. 21. All manhole lids and access, sampling or inspection ports trust have locking covers and be located at ground level. 22. All pressure systems with a pump chamber outlet higher than the drainfield must have a 1/8"hole drilled in the discharge pipe above the pump to prevent siphoning. 23.All transport lines under driveways or parking areas must be as d to prevent crushin•. 24. Homeowner is responsible for all property lines. R 0 v E AUG 3 1 2023 N COUNTY ENVIRON MENTA JBW L HEALTH of �a
