This is a repair, existing drainfield full of roots and sludge 2. 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. 3. Concrete tanks required 4. Pump controls to be set at time of installation 5. Install system during dry weather with acceptable soil conditions 6. Gravel based drainfield required. 7. Clean C-33 sand to be used. 8. The tanks may be moved as necessary to accommodate building requirements. Septic tank location must meet all required setbacks. 9. Keep wheeled vehicles off the drainfield area before, during and after installation. Tracked equipment only, 10, 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. 11. Curtain drains can be no closer than 10 upgradient and 30' down gradient of the drainfield 12. Exposed restrictive layers, cuts, banks, etc can be no closer than 50' downhill from the drainfield. 13, Install access risers on the septic tanks, valve box and ends of laterals. 14. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank. 15. Lids must form a water and gas tight seal with the access risers 16.

The 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. 20. Install laterals with contour of the ground 21. Install trench bottoms level and always maintain a minimum of six inche native soil 22. Install locator tape on top of all drainfield laterals. 23. Install threaded clean outs at the ends of all laterals (caps must exte wi six inches of finish grade and be in a valve box as shown on diagram. 24, Install audio/visual alarmFilter fabric required over drain rock prior at _ ig�F. e drain rock extends above the wlgnal,gie'd6 'rum the filter fabric as Zhes in the trench wall.
