Re: Bayside Meadows Proposed Piat
I have reviewed the preliminary septic system designs fo the 5 proposed lots in Bayside Meadows
Addition. The designs show two standard septic sites for e ch lot with a proposed house site. Lots 2-5
would allow some flexibility in final house location. Lot 1 d s not allow for any flexibility and should be
noted as such. The septic sites split much of the lot and a ng with the wetland limits the house site to
basically where it is proposed.
I have stamped approvals for the five proposed sites. If yo have further questions please let me know.

Proposed Lot 5
Orono,Hennepin.County
This on-site Sewage Treatment System is partially designed fo a Type l,five-bedroom home in
accordance with the Minnesota Pollution Control Agency Cha ter 7080 and local ordinances.
Once the house size,location and septic primary and future sit s are chosen this design can be completed.
T`he periodically saturated soils were located at 12-16 Inches( ottled soil).Due to the periodically
saturated soils,a pressurized mound system will need to be ins lled to treat the septic effluent.The bottom
of the treatment area must be located at least 3'above the sa ted soils.
The soils at a depth of l2"have a percolation rate averaging 8 I.
The absorption areas do not overlap.
All tanks need to be insulated if there is less than two feet of c ver over the top of the tanks.A filter needs
to be installed on the second tank. Clean outs must be installed n the end of the laterals for maintenance.
A pumping chamber will need to be installed to lift the effluen to the treatment area.The power supply and
switches must be located outside the manhole and pumping ch ber in a weatherproof enclosure. A
warning device must be installed with a light and sound device this is in case of a pump failure.
Use 7/32 inch aerforations on the laterals.
Keep all heavy equipment off of the proposed treatment ar s before and after construction.The
treatment area must be fenced off before construction begi s.This Design is not valid&the System
will need to be relocated if faiture to protect the areas prop sed for the On-Site Sewage Treatment
systems occurs.
Nothing other than gray water,(laundry,showers,ect.)human ater&toilet tissue should be disposed of
into the septic tanks_Garbage disposals are not recommended. ddirives must not be used;they may cause
harmful damage to your septic system.lt is recommended that ou pump the septic tank every year for 1
tank,every two years for two tanks.
