Installation Notes
Pressure Distribution System:
32021-53-02011 450 E Parkway Blvd
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.
1. Drainfield filled with roots. Limited reserve area, residence is on post and pier, no
foundation .
-2. Timer to be set at 180GPD
3. Keep wheeled vehicles off the drainfield area before, during and after installation.
Tracked equipment only
4. 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.
5. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the
drainfield
6. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the
drainfield.
7. Install access risers on the septic tanks, valve box and ends of laterals.
8. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank.
9. Lids must form a water and gas tight seal with the access risers.
10. Install effluent filter at the septic tank outlet.
11. This system must be installed by a Mason County Certified installer.
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 laterals with contour of the ground.
15. Install trench bottoms level and always maintain a minimum of six inches into native
soil..
16. 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 diagram.
17. Install audio/visual alarm.
18. Filter fabric required over drain rock prior to backfilling. If the drain rock extends a
the original grade, run the filter fabric at least 2 inches down the trench wall into gi
grade.
