t I <br /> SYSTEM DESIGN • <br /> FOR JOHN PRUDDEN <br /> 315 WOODHILL ROAD <br /> Enclosed are results of soil borings and percolation tests <br /> taken on the Prudden property and system design material for the <br /> pressure mound system needed. The flatter area tested by the <br /> guest house looks to have enough room to treat 5 bedrooms or <br /> 750 gallons of wastewater per day, while hopefully saving the 30" <br /> oak tree. An additional 12 . 5 feet of length could be added if <br /> the oak tree were removed, thus allowing for 6 bedrooms or 900 <br /> gallons per day. <br /> Two additional soil borings ( 3 & 4 ) were taken in a flat <br /> open area to the south-southeast of the main', house and soils <br /> encountered there indicated this would be a very good' area for <br /> another future mound system. <br /> In addition to the system design information enclosed, two <br /> septic tanks of at least 1250 gallons and a pumping tank of 1000 <br /> gallons would be needed. All construction and materials ' must ad- <br /> here to the provisions of the City of Orono, and drainage should <br /> be diverted from the mound area. <br /> If any other information is needed, please, .contact me . -- • <br /> - <br /> • <br /> Sincerely, <br /> PERCOR, <br /> INC. <br /> Mark S .
