Design retorts are not considered approved unless accompanied by the "City of Orono Septic System Approval" cover sheet signed by the City Inspector. 6. The following inspections will be required for all septic systems: a) Pre-installation site inspection to include inspector, installer, and general contractor. b) Tank installation prior to covering. c) Drainfield trench installation prior to covering. (For mounds, inspection is required after rough-up but prior to sand placement, and again during pressure distribution piping installation in the rock bed.) d) Final inspection to verify proper final cover depths and to verify that all pump station (where required) components are functional and comply with codes. 7. Individual holding MPCA Installer Certificate shall be present during all inspections. 24-hour notice is required for all inspections. *************************************************************************** JOB SITE ADDRESS: L(1 * Occupancy Type: Residential k Commercial Other 71, Owner's Name: o.-v U % ' Phone: - 4/20 .5762 Mailing Address: f 7 N 0 'rut ,(1 City: /14(12660c fti it Zip: SS"4S Septic Contractor's Name: e 1 o u e J--J t (I (L j c_ Bus.

Determine pump capacity: 1. Minimum suggested is 600 gallons per hour (10 gpm) - to stay ahead of water use rate 2. Maximum suggested for deliv• •, to a drop box of a home system is 2700 gallons per hot ~ (45 gpm) to prevent buildup of pressure in drop br 3. Use value from design of pre distribution system SELECTED PUMP CAPACITY 4 gpm B. Determine head requirements: 1. Elevation difference between pump and point of discharge feet yr 2. If pumping to a pressure distribution system, add 5 feet for pressure required at manifold feet 3. Friction loss a. Enter friction loss table with gpm and pipe diameter. Read friction loss in feet per 100 feet from page F-18. F. L. = Z , i, `� ft/100 ft b. Determine total pipe length from pump to discharge point; Add 25 percent to pipe length for fitting loss, or use a fitting loss chart. Equivalent pipe length = 1.25 times pipe length = 1.25 x 3-0 _ 4),5- feet /"."\ • c. Calculate total friction loss by multiplying friction loss in ft/100 ft by equivalent pipe length. Total friction loss = x ( c _ / , 7 feet 4. Total head: required is the sum of elevation difference, special head requirements, and total friction loss. + + TOTAL HEAD / c7 feet C. Pump selection 1. A pump must be selected to deliver at least YO gpm with at least feet of total head. D. To maximize pump life select sump size for 4 to 5 pump operations per day. E. Calculate drainback 1. Determine total pipe length, feet. 2. Determine liquid volume of pipe, gallons per 100 feet. (See page E-18) 3. Multiply length by volume: Drainback quantity = feet x gallons/100 ft = gallons 4. Suggested drainback quantity is 10 percent of pumped quantity. A larger drainback percentage will decrease pump station efficiency slightly but pumping energy costs are usually a relatively small part of the total household energy costs.
