1. 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 tanks required
5. Pump controls to be set at time of installation RFOR 170 GIRD.
6. The tanks may be moved as necessary to accommodate building requirements. Septic
tank location must meet all required setbacks.
7. Keep wheeled vehicles off the drainfield area before, during and after installation.
Tracked equipment only,
8. 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.
9. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the
drainfield
10. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the
drainfield.
11. Install access risers on the septic tanks, valve box and ends of laterals.
