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. 15. Install bed with contour of the ground 16. Install trench bottoms level and always maintain a minimum of six inches into native soil 17. Install locator tape on top of all drainfield laterals. 18. Install threaded clean outs at the ends of all laterals (caps must extend to within six inches of finish grade and be in a valve box as shown on diagram. 19.
