John Serena <br /> 4605 Watertown Rd. <br /> Orono , Henn. Co. , MN <br /> (2) <br /> The power supply and switches must be located outside the manhole and <br /> pumping chamber in a weather proof enclosure . A warning device must <br /> be installed with a light and sound device, this is in case of a pump <br /> failure . Mercury floats are a good method. <br /> All neighboring wells are located greater than 100 ' away from the <br /> proposed treatment area. <br /> The existing tanks are old and will need to he replaced, abandoned <br /> pumped & filled with soil . If the tanks are solid concrete, <br /> water tight they may be used upon approval by the local Inspector. <br /> The piping in the house is cast iron and may need to be replaced. <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 and maintenance, this system should have no <br /> problem in treating septic effluent effectively. <br /> Nothing other than gray water, (laundry, showers, etc. ) human <br /> waste & toilet tissue should be disposed of into the septic tanks . <br /> Garbage disposals are not recommended. Smaller amounts of laundry <br /> soaps , dish soaps , cleaning agents, etc. are better for the system. <br /> Antibacterial soaps & chlorine agents may kill the bacteria needed <br /> to treat septic effluent properly. Additives are not recommended, <br /> they may cause harmful damage to your system. Recommend to pump <br /> & clean your tanks by a certified pumper every year if you have <br /> 1 tank & every 2 years if you have 2 tanks to insure proper <br /> maintenance. <br /> Steven B.
