Prepared site plan is not a surve l It's the owner's responsibility
y, po sibility to verify property lines, utility
lines (water, sewed, power, phone and gas) prior to installation.

2. Timer to be set at 270 GPD
3. Keep wheeled vehicles off the drainfield area before, during and after installation.
Tracked equipment only
4. All ground, surface water ant roof drains must be diverted away from the septic tanks

collect on or around them. Use swales, berms, catch basin and tight lines, curtain drains,
etc. to divert all waters.
5. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the
drainfield
6. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the
drainfield.

bedroom. The minimum design flow per bedroom per day is the operating capacity of
ninety gallons multiplied by t.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;
14. Install laterals with contour of the ground.
15. Install trench bottoms level and always maintain a minimum of six inches into native
soil..
16. Install threaded clean outs atithe ends of all laterals (caps must extend to within six
inches of finish grade and bein a valve box as shown on diagram.
17. Install audio/visual alarm.
