Tests consisted of one soils boring to eight feet in depth and six test holes 24 to 36 inches in depth. Soils encountered were topsoil, silty clay, clay and clay till. No water waF observed. A three-bedroom house is proposed. Percolation rates in the primary drain field area are ten minutes per inch. At this rate, the drain field area required is 500 square feet. At the alternate drain field site the average rate was 16 minutes per inch requiring a drain field area of 600 square feet. Both areas range in altitude from two to six feet below the proposed house site. The adjacent wetlands lies approxir^ately ten feet below the lowest point of each drain field site. It is recommended that a 400 gallon capacity dosing chanber, with siphon, be installed between the septic tanks and the distribution box. It is further recommended that the drain field, if installed at the primary site, consist of four, 100 -foot lines spaced seven feet apart and with two -foot trench bottom widths. All installations should comply with the Orono Individual Sewage Disposal System Code of `tininur; Standards. The proposed water well location, shown on the sketch, would be acceptable for either drain field location. `;r.

Minnesota No: Residential Percolation Test John Burger - 3700 Bayside Road Dear Mr. McCombs: As you requested. we have re-examined the subject site with regard to elevations. The proposed primary drain field. lying northeast of the house site and along the east property line, has its upper (south) end approxi- mately five feet below the ground level at the proposed house. The lower (north) end of the drain field is &p - proximately ten feet below the upper end. or approximately 15 feet below the ground level at the house site. This amount of relief indicates a serial -type construc- tion for the drain field. General drain field dimensions should be 30' x 100' with drain tiles running east -west in 30 -foot lengths, seven feet apart. If further data is reavired, please advise. Sincerely. EUGENE A.
