, � <br /> • .`. <br /> Maintenance <br /> The homeowner of an individual sewage treatment system must properly have the septic <br /> tank(s)cleaned by a licensed pumper every three years, at a minimum, in order to prevent <br /> the sludge from reaching any point closer than 12"from the bottom of the outlet baffle, <br /> or the scum from reaching a point closer than three inches higher than the bottom of the <br /> outlet baffle. Ple�se note that this is required to eztend the life of vour svstem. <br /> Drainage and final landscaping <br /> All surface water must flow away from the tank and drain field area. A drainage plan <br /> should be completed to insure tha.t surface run off from the hill,buildings, and driveway <br /> drain away from the system. <br /> To help the functioning of the system, it must be sodded or seeded. This will prevent <br /> erosion, and assist in disposal of the water. Shrubbery may be planted outside of the <br /> perimeter of the drain field,but not over the drain field. <br /> A water meter may be installed to measure all water entering the system. <br /> NOTE: If a chlorinated hot tub is installed in the home the water from this is <br /> considered clean and should be discharged somewhere other than the septic system. <br /> Any other water products that generate"clean"w�ter should discharge somewhere <br /> other than the septic system. Ezamples of these include: sump pumps, pools,water <br /> softener,iron filter,self-humidifying furnace. To plumb these into the system will <br /> overload it and void any warranties. <br /> GENERAL <br /> The contents of this report are to be applied to the listed properiy only and are copy <br /> righted.
