System was installed in 1989, appears to be right on top of the till layer. Drainfield is clogged with roots. 2. Concrete tanks required 3. Pump controls to be set at time of installation . 4. Install system during dry weather with acceptable soil conditions 5. The tanks may be moved as necessary to accommodate building requirements. Septic tank location must meet all required setbacks. 6. Keep wheeled vehicles off the drainfield area before, during and after installation. Tracked equipment only, 7. All ground, surface water and roof drains must be diverted away from the septic tanks and drainfield. Ensure the final grade slopes away from these areas and water doesn't collect on or around them. Use swales, berms, catch basin and tight lines, curtain drain-, etc. to divert all waters. 8. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the drainfield 9. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the drainfield. 10. Install access risers on the septic tanks, valve box and ends of laterals. 11.

Deviation from this design without prior approval from the designer and Mason County Health Department will make this design null and void. 16. This design was sized per Washington Administrative CodeWAC246-272A-0230. The operating capacity is based on 45 gallons per day per capita with two persons per bedroom. The minimum design flow per bedroom per day is the operating capacity of ninety gallons multiplied by 1.33. This results in a minimum design flow of one hundred twenty gallons per day. This creates a surge factor of 33% but anticipated flow is ninety gallons per bedroom per day. 17. Install laterals with contour of the ground 18. install trench bottoms level and always maintain a minimum of six inches into native soil 19. Install locator tape on top of all drainfield laterals. 20. Install threaded clean outs at the ends of all laterals (caps must extend to within six inches of finish grade and be in a ve box as shown on diagram. 21. Install audio/visual alarm 22.
