Installation Notes
Gravity Distribution System:
3531 w Shelton Valley Rd 41902-21-90020
1. Gravel based drainfield required.
2. Concrete tanks required
3. System to be installed by a licensed Mason County installer. Self install must
follow Mason County Healty Departments requirements.
4. Install system during dry weather with acceptable soil conditions
5. Keep wheeled vehicles off the drainfield area before. during and after installation.

collect on or around them. Use swales, berms, catch basin and tight lines, curtain drains,
etc. to divert all waters.
7. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the
drainfield
8. Exposed restrictive layers, cuts, banks. etc. can be no closer than 50' downhill from the
drainfield.

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.
