Installation Note
Pretreated Pressure Distribution System:

1. 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.
2. IThis is a repair. Sandfilter is surfacing to the surface. Original design(SWG98-
0531)took a 50% reduction for the sandfilter. We are replacing the sandfilter with
a BNR500, adding timed dosing, adding 300sf of drainfield. The existing
drainfield is functionintg.
3. Concrete tanks required
4. Low provile infilitrators required
5. �Ajl ground, surface water and roof drains must be diverted away from the septic tanks
nd drainfield. Ensure the final grade slopes away from these areas and water doesn't
ollect on or around them. Use swales, berms, catch basin and tight lines, curtain
drains, etc. to divert all waters.
6. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the
drainfield
7. xposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from
the drainfield.
6. Install access risers on the septic tanks, valve box and both ends of laterals.
9. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank.
10. Lids must form a water and gas tight seal with the access risers
11 this system must be installed by a Mason County Certified installer or
12. Deviation from this design without prior approval from the designer and Mason County
Health Department will make this design null and void.
13. 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.
14. Install bed with contour of the ground
15. Imstall trench bottoms level and always maintain a minimum of six inches into native
soil
16. Install locator tape on top of all drainfield laterals.
17. Install threaded clean outs at the ends of all laterals (caps must extend to within six
inches of finish grade and be in a valve box as shown on diag
18. Install audio/visual alarm
19. Filter fabric required over drain rock prior to backfilling. If th rai ck extends above
the original grade, run the filter fabric at least 2 inches do c e t - h wall.
