INSTALLATION/MAINTENANCE
PRESSURE DISTRIBUTION SYSTEM
1. Install laterals with contour of the ground.
2. histall trench bottoms level and at all times a minimum of six inches into the native
soil.
3. Install locator tape on top of all drainfield laterals.
4. Install observation ports as indicated on the plot plan(minimum two per drainfield
with bottom extending to the drain rock/native soil interface).
S. Install drainfield during dry weather and soil conditions, and soil smearing must be
eliminated by hand raking.
6. Install threaded clean-outs at the ends of all laterals(cap must extend to within 6
inches of finished grade and be marked with locator tape).
7. Install audio/visual high water alarm.
8. Install 1/8 inch mesh non-corrosive pump screen(min. 12-sq. ft. surface area,not to
interfere with controls or floats).
9. Install check valve in pump outlet line to prevent system from draining back into the
pump chamber.
I
10. Filter fabric required over drain rock prior to backfilling. If the drain rock extends i
above natural grade, ran the fiher fabric at least 2 inches down the trench wall.
11.Divert all storm water run-off away on-site sewage system.
12. No curtain drains allowed within 10 ft. or the up-slope edge of the drainfield and
reserve area
13. No curtain drains allowed within 30 ft. of the down-slope edge of the drainfield and
reserve area.
14. Have the septic tank and pump chamber pumped or inspected every three to five
years.
15.Inspect floats,clean pump screen and test water alarm every 6— 12 months as needed.
1%V6.
16. All materials and workmanship must meet County and State regulations.
17. Septic tank risers to be at or above finish grade.
18. Deviation from this design without prior approval from the Designer and Mason
County Health Department will make this design null and void.
19. Pump chamber lid to be above finish grade.
20. The on-site septic system owner is responsible for properly operating and maintaining
the OSS and shall:
a) Determine the level of solids and scum in the septic tank once every
three years.
b) Employ an approved pumper to remove the septage from the tank
when the level of solids and scrum indicates that removal is necessary.
c) Protect the OSS area and the reserve area from:
1. Cover by structures or impervious material
2. Surface drainage
3. Soil compaction by vehicular traffic or livestock
4. Damage by soil removal and grade alteration
d) Keep the flow of sewage to the OSS at or below the approved design
both in quantity and waste strength.
21.High strength waste will increase the depth of the biomat in a drainfield, causing a
decreased flow through the biomat and possible ponding or flooding of the drainfield.
High strength waste in a residence is usually related to the`9ifestyle,or habits of the
home,generally resulting from one or more of the following:
a) Excessive use of a garbage disposal
b) Consecutive loads of laundry done all on one day
c) Excessive bleach or detergents with added whiteners
d) Dishwashing, showering, and laundering all at the same time
e) Medications—antibiotics can kill or impair the biological process in
the septic tank.
t) beaky plumbing(hydraulic overloading)
