. . <br /> , 2675 Fox Street <br /> Orono <br /> ( 2) <br /> The manifold and supply line pipe must have back drainage to the pumping <br /> chamber . The distribution pipes shall have their ends capped. �e sure <br /> the rock and sand fill material are clean. The sod layer below the <br /> entire mounded area must he turned over , just break up the sod , he sure <br /> not to over work. <br /> The power supply and switches must be located outside the manhole and <br /> pumping chamb�r in a weather proof enclosure . A warning device must <br /> be installed with a light arid sound �evice , this is in case of a pump <br /> f_ailure . Mercury floats are a good method . <br /> The supply line will need to be installed around the east end of <br /> excavated ditch within 5 ' of the property line . Due to the high <br /> water table , the supply line will need to be installed shallow <br /> and be insulated to prevent freezing . Only the manifold and a <br /> small section of the supply line will have drain back. Recommend <br /> to add 12" to 18" of fill to cover the pipe north of the excavate� <br /> ditch near the east property line . <br /> The existing tanks are block type and will need to be abandoned , <br /> pumped & filled with soil . <br /> �11 neighboring wells are located greater than 100 ' away from the <br /> proposed treatment area . <br /> Keep all heavy equipment off of the proposed treatment area before and <br /> after construction. The treatment area should be marked off before <br /> construction. This Design is not valid & the System will need to <br /> be relocated if failure to protect the areas proposed for On-Site <br /> Sewage Treatment occurs . <br /> With proper installation an� maintenance , this system should have no <br /> problem in treating septic effluent effectively. <br /> CONT ' D <br />
