When to Pump the Septic Tank
A properly designed septic tank system will have a septic tank with sufficient volume to accumulate solids for several years. Over time the solids accumulate and begin to fill up the septic tank. If these solids are not periodically pumped out, suspended solid particles may begin to flow into the absorption field. These solids will eventually clog the absorption field and may require the installation of a new absorption field. Newer septic tank systems are required to have an effluent filter located on the outlet of the septic tank. The purpose of this filter is to protect the absorption field by trapping suspended solids. If the septic tank is not pumped out periodically, the effluent filter may become clogged causing waste water to back up into the house. A specific determination of when it’s time to pump a septic tank can be made by having the depth of the solids and level of scum buildup checked periodically. New septic tanks have an access port over the inlet and outlet tees to facilitate the cleaning of the effluent filter and pumping of the tank. Two factors primarily affect the pumping frequency required. The first factor is the holding capacity of the septic tank. The more people using a system, the faster the solids build up, and the more frequently the tank will have to be pumped. A larger capacity system provides better treatment and requires less pumping. The standard three or four bedroom house has a 1000 gallon septic tank. The second factor is the amount of solids in the waste water. If you have a garbage disposal, you will have to pump out your septic tank more frequently. The use of a garbage disposal may increase the amount of solids in a septic tank by as much as 50%. Pouring grease or other non-biodegradable types of solid waste drown the drain will add to the accumulation of solids. Homes with garbage disposals are required to increase the size of their septic tank by 50%. A three or four bedroom house with a garbage disposal is required to have a 1500 gallon septic tank. The recommended pumping frequency for pumping out septic tanks can be estimated based on assuming a waste water retention time of 24 hours and assuming that 50% of the solids are digested by bacterial action in the tank. The following table can be used as a guide for average home water usage without a garbage disposal.
Direct all waste water from the home into the septic tank. This includes all sink, bath, shower, washing machine, toilet and dishwasher waste water. Any of these waste waters can contain disease causing organisms and pollutants. The department does allow separate black water and gray water systems for water reuse. All gray water must be disposed of in an on site sewage management system.
• Practice water conservation to avoid overloading the on site sewage system. Repair dripping faucets and leaking toilets. Run dishwashers when full. Do not do all your laundry in one day. Space out the washing machine use over the week. Replace old fixtures with water saving fixtures.
• Do not direct water from gutter downspouts, sump pumps or subsurface drains into the septic tank. The on site sewage management system is designed based on an estimated daily water use. Excess water directed into the septic tank will cause a hydraulic failure.
• Use commercial bathroom cleaners and anti-bacterial soaps in moderation. Treatment in the septic tank depends on natural bacteria. The Department does not recommend the use of septic tank additives. These products are not necessary for proper system operation.
• Do not plant trees or bushes on top of the absorption line. Root intrusion may damage and block the absorption line.
• Landscape the site to allow surface water to drain off of the absorption field area. Divert roof drains from the absorption field area. Standing water over the absorption field will cause soil saturation and potential system failure.
• Do not park or drive over the septic tank or absorption field. This can damage the septic tank and absorption field. Soil compaction can occur reducing the ability of the soil to absorb the waste water from the system.
• Do not pour grease, oil, paint or other chemical products down the drain. Do not put non-biodegradable items such as cigarette butts, feminine hygiene products, condoms, disposable diapers or other similar solid waste into the septic tank.
