Treatment of the effluent occurs as it moves through the sand and into the natural soil.Įvery new mound is required to have a designated replacement area. The effluent leaves the pipes under low pressure through small diameter holes, and trickles downward through the gravel and into the sand. Septic tank effluent is pumped through the pipes in controlled doses to insure uniform distribution throughout the bed. Within the sand fill is a gravel-filled bed with a network of small diameter pipes. The mound is a drainfield that is raised above the natural soil surface in a specific sand fill material. When the pump is off for more than 6 hours, reduce your water use to a minimum. Once the reserve storage in the chamber is all used up, the plumbing in your home can backup. With additional effluent in the chamber, the pump may dose a volume more than the mound can handle. Effluent will continue to collect in the pump chamber until the pump starts operation. Taking action to protect the mound from overloading after a prolonged power outage or pump failure.Inspecting the filter and cleaning it when necessary is quick and easy, and prevents costly damage from solids entering the system. Screening or filtering the septic tank effluent provides an effective way of preventing solids from clogging the pump and pipes. Installing a septic tank effluent filter or pump screen, if your system does not have one.If the alarm panel has a “push-to-test” button, it should be utilized regularly. Check electrical parts and conduits for corrosion. Pump maintenance should follow the manufacturer’s recommendations. Checking the pump chamber, pump and floats every year and replacing or repairing worn or broken parts. A piece of nylon rope or other non-corrosive material should be attached to the pump for taking the pump in and out of the chamber. The pump discharge pipe should have a union and valve for easy removal of the pump. It should be on an electrical circuit separate from the pump. The alarm should consist of a buzzer and an easily visible light. The float is set to start when the effluent in the pump chamber rises above the “on/off” float. If pump timer controls are used, the alarm also will warn you of excessive water use in the home or leaks into the system. The high water alarm float starts an alarm to warn you of any pump malfunction. Timer controls are set to produce both the length of the dose and the interval or rest period between doses. Control floats are set to turn the pump “on” and “off” at levels for pumping a specific volume of effluent per dose. The pump action can be controlled either by the use of control floats or by timer controls. The chamber contains a pump, pump control floats and a high water alarm float. The pump chamber is a concrete, fiberglass or polyethylene container that collects the septic tank effluent. Such products are not necessary for the proper functioning of a septic tank, nor do they reduce the need for routine tank pumping. Avoiding the use of any type of chemical or biological septic tank additive.For information on the proper disposal of hazardous household waste, contact Humboldt Waste Management Authority. Never put materials such as grease, cooking oils, newspapers, paper towels, cigarette butts, coffee grounds, diapers, sanitary napkins, solvents, oils, paint or pesticides into the tank. Avoiding the flushing of harmful material into the septic tank.The use of a garbage disposal is highly discouraged because it will increase the amount of solids entering the tank and require more frequent pumping. If the tank is not pumped periodically, solids escaping from the septic tank will clog the pump and mound. Inspecting your septic tank once every year and pumping it when needed.From the tank, the effluent flows by gravity to the pump chamber. It has been partially treated but still contains disease-causing bacteria and other pollutants. The wastewater leaving the septic tank is a liquid called effluent. A liquid layer exists between the solids layers and passes from one chamber to another. Most of the lighter solids, such as grease and oils, rise to the top and form a scum layer. Heavy solids settle to the bottom where bacterial action partially decomposes them. Wastewater from your home flows into the tank. The typical septic tank is a large dual-chambered buried container made of concrete, fiberglass or polyethylene.
