K <br />SITE EVALUATION REPORT <br />For Cheyenne Builders <br />Sewage Treatment System <br />General Information <br />This design is for a Type 1, 5 bedroom home and in accordance with the Minnesota Pollution <br />Control Agency Standards and local ordinances. <br />A seasonally high water table was evidenced at 18 inches of depth in Soil Borings 3, 4, 5 & 6. <br />The slope is about 4%. <br />The soils at a depth of 12 in Test Holes 5 thru 7 have a percolation rate of 34 minutes per inch. <br />All neighboring wells are located more than 100' away from the proposed treatment area. <br />NOTES: <br />Keep all heavy equipment off the proposed treatment area before and after construction <br />as much as possible. The treatment area should be marked off before construction. <br />With proper installation and maintenance this system should have no problem in treating <br />septic effluent effectively. <br />It is recommended that the septic tanks be pumped every 2 years. <br />MOUND SYSTEM: <br />Flow: 5 bedroom = 150 gallon/day/bedroom 150 x 5 = 750 gallons per day. <br />750 GPD x 1.00 = 750 square feet. <br />10-foot wide rock bed 75 feet long = 750 square feet <br />CONSTRUCTION EQUIPMENT: <br />A rubber -tired tractor may be used for plowing or disking to prepare the soil surface but in no <br />case shall a rubber -tired tractor be used after the surface preparation is completed. A crawler <br />or tract -type tractor shall be used for mound construction. <br />SOIL SURFACE PREPARATION: <br />The discharge pipe from the pump to the mound area shall be installed prior to soil surface <br />preparation. The trench excavated to install the discharge pipe shall be carefully backfilled and <br />compacted to prevent seepage of effluent. <br />PAGE 2 <br />
