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

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.
19. Install laterals with contour of the ground.
20. Install tr nch bottoms level and always maintain a minimum of six inches into native soil.
21. Install tor tape on top of all drainfield laterals.
