The old system consists of a 1,000-gallon singlo-comparhnent septic tank followed by 80 lineal feet (240 s.f.)of gravity trench drainfield. This sizing would historically be rated as a 2-bedroom septic. The system was discovered to be failing at a recent inspection. The tank is homemade and shows a low water level,the d-box was full of dirt and the drainfield was partially crushed,has fragile pipe and was not taking water the way it should. The new owner would like to develop this property and be able to build a new 2-bedroom home so we are proposing a full septic upgwmde. The old s to be decommissioned or removed and the old drainfield is to be abandoned. . 4"..�+J' Proposed is a new 1,000-gallon operating capacity minimum 2-compartment septic tank with an effluent filter followed by a new 1,000-gallon minimum flood capacity pump chamber. The new drainfield consists of 300 s.f.of shallow pressure trench 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 is a non-compliant repair with 12"+vertical separation. The drainfield meets 100'+ setback to surface water and wells and we have also designated a full reserve drainfield area.

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 mbar). 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 and block under pump. Pull bio-tube every 6-12 months and flush back into tank. 9. Install anti-siphon valve above pump in pump chamber to prevent the pump chamber from siphoning into the drainfield. 10.Install 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. 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. 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 trench 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 chamber pumped or inspected every 3 years minimum. 17.No vehicular traffic over drainfield area. 18.Inspect floats, clean filters, and test high water level alarm every 6-12 months as needed. 19.
