<br /> This on-site Sewage Treatment System is partially designed for a Type 1,five-bedroom home in
<br /> accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances.
<br /> Once the house size, location and primary septic site are chosen this design can be completed.
<br /> The periodically saturated soils were located at 16-28 inches(mottled soil).Due to the periodically
<br /> saturated soils,a pressurized mound system will need to be installed to treat the septic effluent.The bottom
<br /> of the treatment area must be located at least 3' above the saturated soils.
<br /> Due to limited space.The mound rock bed must be split into two 32 foot rock beds.The absorption area of the
<br /> proposed rystem does not overlap.A retaining wall will be needed to keep the side toe five fee[from the property line.
<br /> This system is designed with duel rock beds usina non-level pressure distribution.See design sheets.Use 7/32
<br /> inch perforations on the laterals.See desien sheets.
<br /> The soils at a depth of 12"have a percolation rate averaging 8 MPI.
<br /> All neighboring wells are located gseater than 50'away from proposed treatment area
<br /> 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
<br /> installed on the second tank Clean outs must be installed on the end of the laterals for maintenance.
<br /> A pumpiog chamber will need to be installed to lift the effluent to the treafinent area.The power supply and switches
<br /> must be located outside the manhole and pumping chamber in a weatherproof enclosure.A warning device must be
<br /> installed with light and sound devices;this is in case of a pump failure.The manifold and supply line must have back
<br /> drainage to the pumping chamber.The distribution pipes shall have their ends capped. Be sure the rock and sand fill
<br /> materials are clean.The sod layer below the entire mounded area must be turned over,just break up the sod and be sure
<br /> not to over work.
<br /> Keep all heavy equipment off of the proposed treatment areas before,during and after construction
<br /> With proper installation and maintenance,this system should have no problem in treating septic ei�luent effectively.
<br /> Nothing other than gray water,(laundry,showers,etc.) Human water and toilet tissue should be disposed of into the
<br /> septic tanks. Garbage disposals aze not recommended. Additives must not be used;they may cause hannful damage
<br /> to your septic system. It is recommended that you pump tanks every two years.
