32127-51-00295 830 E St Amdrews Dr
1. Drainfield installed in 1978. It is in the driveway. Root bound.
2. The prepared site plan is not a survey. It's the owner's responsibility to verify property
lines, utility lines(water, sewer, power, phone and gas) prior to installation.
3. Area of drainfield must be protected from vehicle traffic.
4. BNR pump tank must he traffic rated or protected from traffic
5. This is a repair, drainfield root bound and is located partially under outbuilding.
6. The tanks may be moved as necessary to accommodate building requirements. Septic
tank location must meet all required setbacks.
7. Transport line must be cased.
B. Keep wheeled vehicles off the drainfield area before, during and after installation.
Tracked equipment only,
9. 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
drains, etc. to divert all waters.
10. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the
drainfield
11. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from
the drainfield.
12. Install access risers on the septic tanks, valve box and ends of laterals.
13. Make sure septic lank risers are epoxied or caulked to cast in riser rings on tank.

16. Deviation from this design without prior approval from the designer and Mason County
Health Department will make this design null and void.
17. 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.
18. Install bed with contour of the ground
19. Install trench bottoms level and always maintain a minimum of six inches into native
soil
20. Install locator tape on f all drainfield laterals.
21. Install threaded clea ut t the ends of all laterals (caps must extend to within six
inches of finish gra nd y n a valve box as shown on diagram.
22. Install audio/visu r
23. Filter fabric req ck prior to backfilling. If the drain rock extends above
the original gr ruff I�trj is at least 2 inches down the trench wall. \\
