This on-site Sewage Treatment System is designed for a Type 1, five -bedroom home in accordance with
the Minnesota Pollution Control Agency Chapter 7080 and local ordinances.
The periodically saturated soils were located at 16-24 inches (mottled soil). Due to the periodically
saturated soils, a pressurized mound system with 6 inches of rock 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. This system
is designed with 6 inches of rock.
A 2250 -gallon combination septic tank or its equivalent is designed for this site. All tanks need to be
insulated if there is less than two feet of cover over the top of the tanks. Clean outs must be installed on the
end of the laterals for maintenance.
Use 7/32 -inch perforations on the laterals.
A 1250 -gallon pumping chamber will need to be installed to lift the effluent to the treatment area. The
power supply and switches must be located outside the manhole and pumping chamber in a weatherproof
enclosure. A warning device must be installed with light and sound devices; this is in case of a pump
failure. A flow measurement device must be installed. Including but not limited to a water meter, event
counter, running time clocks or electronically controlled dosing.
Keep all heavy equipment off of the Proposed treatment areas before durinn and after construction
The area around both sites must be fenced off by the contractor before any construction begins
With proper installation and maintenance, this system should have no problem in treating septic effluent
effectively. Nothing other than gray water, (laundry, showers, etc.) Human water and toilet tissue should be
disposed of into the septic tanks. Iron filters and large volume water treatment systems cannot go into
the septic system. 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 septic tanks every two years.
Sincerely,
Joseph J. Olson
