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. There is no records on this parcel. System is probably 50 plus years old. System has been driven on and is very close to the till layer. 3. Gravel based drainfield required 4. Concrete septic and pump tank required 5. The tanks may be moved as necessary to accommodate building requirements. Septic tank location must meet all required setbacks. 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 tanks, valve box and ends of laterals. 11. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank. 12. Lids must form a water and gas tight seal with the access risers. 13.

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 with contour of the ground. 18. Install trench bottoms level and always maintain a minimum of six inches into native soil.. 19. Install threaded clean outs at the ends of all I als (caps must extend to within six inches of finish grade and be in a valve box s wn on diagram. 20. Install audio/visual alarm. 21.
