Marion County <br /> <br /> OREGON <br />COMMUNITY DEVELOPMI~NT <br />DEPARTMENT <br /> <br />S/%ND FILTER S,YSTEM <br />_OPERATION AND MAINTENANCE <br />DATE: .~/ ~/~ <br />N~E: ~-~ <br /> <br />The following information describes the operation and maintenance needs of <br />your Sand Filter System. <br /> <br />The septic tenk acts as a separation chan~er for ~oth s~ttle~ble and floating <br />solid material. The solids are retained in the tank and the liquid is allowed <br />to ~low through the tank. The tank efficiency is partly dependent its capaci- <br />ty. The maintenance of a septic tank serving a Sand Filter system must be <br />pumped a minimum of once every four (4) years. The purpose is to keep the <br />level of solid material in the tank at a level that will not allow the flow of <br />solids out of the tank and into the Sand Filter unit. A_no~if/.cation letter <br />will be sent b~s~d on the system completion date of ~/~ <br />The second tank in the system is a dosing tank which contains the effluent <br />pump apparatus. The system is set to discharge approximately ninety (90) <br />gallons per Cycle for a homesite with a sewage flow up to 450 gallons per day. <br />The pump station should be inspected and tested yearly. Any changes in <br />operating level, leaks in valves o~ piping, presence of foreign matter, etc. <br />should be ~orrected. If your system contains a dosing siphon instead of a <br />pump, the same instructions apply as noted above. <br /> <br />The pump/siphon is surrounded by a small diameter mesh screen. It's purpOSe is <br />to restrict the flow of suspended solid material to the pump. If allowed to <br />pass through the pump, this mate~iai could clog the distribution system in the <br />sand Filter and cause a failure in the system. The screen should be inspected <br />yearly and cleaned as needed, <br /> <br />A garbage disposal in not recommended. ~f you have or plan to add one to your <br />kitchen, caution should be exercised with its use. The added wastes cas <br />contribute to system performance problems. The septic tank should be pumped <br />more often with a disposal on the system, possibly every two (2) years. <br /> <br />There are several things you should no~ do to a sand Filter~ <br /> Flush unusual or high strength wastes such as photographic chemicals or <br /> water softener backwash. <br /> <br />%gno~e leaks in plumbing, especially t¢ilets. The additional water flow <br />can cause system failure. <br /> <br />Significantly change the use of the system thereby increasing the waste <br />strength Or volume such as adult foster care~ beauty salons, etc.. <br /> <br />Use chemical or biological septic treatments as these can have an <br />adverse effect on system components and/or effluent characteristics. <br /> <br /> <br />
