U 4 System may or may not meet current City standards for design,construction or location, but is failing to properly treat and
dispose of the current input, and is endangering a water supply, or is a source of pollution to surface or groundwaters,or is
creating a safety hazard,or is otherwise creating a public nuisance.Please contact the City Inspector to discuss system repair/
replacement procedures. If drainfield replacement is necessary,soil testing will usually be required,and a design and site plan
must be submitted for review.Your contractor must obtain a permit before work is started.

This on-site Sewage Treatment System is designed for a future Type 1 Four-bedroom home in accordance
with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances.
The periodically saturated soils were located at 14"(mottled soil).Due to the periodically saturated soils,a
pressurized mound system will need to be installed to treat the septic effluent.The bottom of the treatment
area must be located at least 3'above the saturated soils.
The soils at a depth of 12"have a percolation rate averaging 8 MPI. ORONO COPY
The existing system conforms to chapter 7080.
All tanks need to be insulated if there is less than two feet of cover over the top of the tanks.A filter needs
to be installed on the second tank.Clean outs must be installed on the end of the laterals for maintenance.
All absorption areas do not overlap.
Keep all heavy equipment off the proposed treatment area.
The existing septic tanks and lift station may be used upon approval of the local inspector.
The manifold and supply line must have back drainage to the pump chamber.The rock and fill materials
must be clean.The sod layer below the entire mounded area must be turned over.Just break up the sod and
be sure not to over work.
Nothing other than gray water.(laundry,showers,etc.) Human water and toilet tissue should be
disposed of into the septic tanks. Garbage disposals are not recommended. Additives must not be
used;they may cause harmful damage to your septic system. It is recommended that you pump the
tank every year for 1 tank,every two years for two tanks.
