RE: Septic System Site Plan for Lot 1, Carriage Hill,Orono, Minnesota.
Dear Steve:
This proposed on-site septic system was designed for a 5 bedroom home, with an estimated flow of 750
gallons per day. The system best suitable for this area will be 418 If. of 10"travelless trench installed
no deeper than 12" below the existing ground level. The seasonal high water table was found at a depth
of 4.0 feet in the Septic area. Two 1300 gallon septic tanks will be adequate for a system of this size.
The site in which this system is proposed has an average existing ground slope of 12%. Percolation
rates for this particular site were found to be between 14-19 MPI.
An alternate septic system has been designed to show that there is enough undisturbed area on the lot to
support another septic system. This system was also designed for a 5 bedroom home. The seasonal
water table was also found at a depth of 48 inches, this site would also require 418 If. of 10"Gravelless
trench. This system will not need to be constructed unless the primary system fails.
Certain precautions will need to be made to protect the areas in which the above referenced septic
systems are proposed. Both primary and alternate septic areas have been or will be staked off. It is
recommended that safety fence be placed around both of the sites for protection during construction of
this project. It is critical that the soil is not disturbed before, during, and after construction of the
system.
These system should treat the septic effluent effectively if the systems are installed properly and are
maintained properly. It is recommenced that the septic tanks be pumped once every two years. This
will reduce the chance of solids reaching the system. It is also recommended not to use excessive
amounts of chlorine, soaps, and chlorine products which can kill bacteria in the septic tanks. This
bacteria is needed to treat the septic effluent
Designing the Future Today...since 1972
If you have any questions in regards to this design, I will be happy to answer them. I can be reached at
(612) 682-2587.
