THIS IS NOT A PERMIT. This is a design approval form which must accompany the site plan. A
permit must be issued to a licensed septic contractor prior to installation.
NOTICE TO INSTALLERS: Any changes to the approved plans must have prior approval of the
inspector(952-249-�600) Call for inspection 24 hours in advance.
ALL DRAINFIELD AREAS MUST BE FENCED OFF prior to building site excavation and
fencing must reinain in place until final site grading. Approval to pour footings will not be granted
until the Inspections Department has verified the primary and alternate sites are protected.
� NO VEHICULAlt TRAFFIC OF ANY KIND is allowed within 20'of tested drainfield sites ever.
ACCEPTED X DENIED By the City of Orono subject to existing regulations and the
following conditions:
1) 1.5' soil on top oi�mound, 1' soil on sides of mound.
21 Sand placement must tollow desi�n.
3) Alarm must be placed inside house. 4)Keep well 50' from septic.
5) An efflueilt filter in pump tank is recommended.
6) Onlv one standard septic site was found so a house tare-down is not allowed.
7 Iron filter and wa�cr softner if installed must be diverted out of s stem.

Re: 1940 6th Avenue N, Orono
The enclosed septic design is for a four bedroom home without a
garbage disposal. The existing plumbing now leaves the house
under the basement floor and is about 8' deep outside. A grinder
pump will be required in the basement to lift the sewage from the
house into the septic tanks as the maximum cover on the top of the
tanks cannot exceed 4'. Due to the lot size, low ground and
driveway & shop area, only one treatment area was located.
Sincerely,
