Installation Notes
Gravity Distribution System:
XXX N E Capston Rock 32315-75-00080
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. Concrete septic tank required
3. Gravel based drainrield required
4. Maintain a 50' attenuation zone down gradient of drainfieldino roads or buildings)
5. Install system during dry weather with acceptable soil conditions
6. Keep wheeled vehicles off the drainfield area before, during and after installation.
Tracked equipment only
7. 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.
8. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the
drainfield
9. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the
drainfield.
10. Install access risers on the septic tank, D-box and observation ports.
11. Make sure septic tank risers are epoxied or caulked to cast in riser rings on lank.

15. Deviation from this design without prior approval from the designer and Mason County
Health Department will make this design null and void.

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.
17. Install laterals or bed with contour of the ground
18. Install trench bottoms level and always maintain a minimum of six inches i native soil
19. Filter fabric required over drain rock prior to back ling. If the drain extends
above the original grade, run the filter fabric at least 2 inches dowole nch wall.
