The city engineer and inspector have reviewed the percolation tests and
proposed septic treatment area on your property. We feel that a drainfield
system can be designed for this area in conformity with Minnesota PCA standards
as proposed in WPC-40 for soils with percolation rates between 60 and 120 MPI.
In this situation, trenches should be constructed 48 inches wide and then lined
with at least 6 inches of loany sand prior to placement of the normal gravel
filter. Ihe design treatment area should be 330 sq. ft. per bedroom.
Plea^ submit a sketch of the proposed field layout and have your contractor
obtain the permit and install the system as soon as possible.
Sincerely,
‘r Olson
^st. Zoning Administrator
