Installation Note
Pretreated Pressure Distribution System:
32224-50-00095 11403 N E North Shore Rd
1. This system has a pump basin at the northeast corner of the residence 4-5' deep, it
pumps up to a 1200 gallon tank that gravity feeds down to the drainfield.
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.
8. 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.
9. Curtain drains can be no closer than 10 upgradient and 30' down gradient of the
drainfield
10. Exposed restrictive layers, cuts, banks, etc can be no closer than 50' downhill from
the drainfield.
11. Install access risers on the septic tanks, valve box and both ends of laterals.
12. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank.
13, Lids must form a water and gas tight seal with the access risers
14. This system must be installed by a Mason County Certified installer or
15. 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
twen allons per day. This creates a surge factor of 33% but anticipated flow is
nin Ilons per bedroom per day.
