OVA
1. The prepared site plan is not a survey. It's the owner's responsibility to verify property A�H`�gCrf"
lines, utility lines (water, sewer, power, phone and gas) prior to installation.
2. Keep laterals in top 12" of original soil
3. Keep wheeled vehicles off the drainfield area before, during and after installation.
Tracked equipment only
4. Concrete tanks required with two risers on all tanks
5. Case transport line at waterline crossing
6. Gravel based drainfield required.
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.

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.
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 laterals (caps must extend to within six
inches of finish grade and be in a valve box hown on diagram.
20. Install audio/visual alarm.
21. Filter fabric required over drain rock prior bac ling. If the drain rock extends above
the original grade, run the filter fabric at �t 2 1 - s down the trench wall into original
T
grade.
