RE: Septic system design and
percolations tests for:
4520 Watertown Rd
Orono MN
1-lennepin County
We were retained by Mr. Miller to evaluate this site for suitability of an individual sanitary
sewage treatment system to handle the sewage flow generated by water-use appliances within a
single family dwelling.
PROCEDURE
A total of six(6)soil percolation tests were performed on May 16, 1995 in areas to the northeast
of the proposed house. Three additional percolation tests were performed on November 10,
1995 to the west of the proposed house,
In addition , six(6)soil boring's were drilled with a 2" i.d.x 3 114" o.d. Hand auger to check for
the position of the ground water table and to identify the underlying soil types. Location of tests
and boring's are shown on the site plan. Three additional sil borings were drilled on November
12, 1995.
The percolation tests were performed in accordance with the provisions of"Minnesota Pollution
Control Agency Rules and Standards Chapter 7080". The percolation test holes were drilled to a
alternate mound depth of 12 inches with a 5" i.d. x 6" ad. auger. Two inches of pea gravel were
placed in the bottom of each hole to prevent scoring, Water was then added to the test holes and
replenished as necessary,maintaining a saturation.,each hole was refilled to a 12-inch head of
water over the bottom,and the percolation tests commenced.
Based on the soils this let will attataia a»,.:t d t-;;p •Ss ptk Intem to handk.nbentes Trastiz..
water. The site must be protected and roped off by the homeowner or contractor.
All equiptment must be kept off of the septic sites.If the site is distrubed we can and will
not warranty future use.
