A concrete or bituminous- covered metal tank where sewage is digested by bacterial action.
A tank plus a leaching pit or trenches in which waste matter is filtered and decomposed through bacterial action. Distinguished from cesspool, a buried, perforated tank that retains most of the waste solids.
A modern device (consisting of a watertight concrete or fiberglass tank) used for the anaerobic decomposition of sewage. Human waste is flushed into the tank from water closets, together with the drainage from sinks, baths, and appliances. The treated effluent is then dispersed to the soil through a drain field, while the sludge is periodically removed (generally by a vacuum truck). A septic tank is an active treatment device, not a cesspool.
Tank into which sewage is drained and then decomposed by a bacteriological process. See Cesspool.
A buried, watertight tank designed and constructed to receive and partially treat raw wastewater. The tank separates and retains settleable and floatable solids suspended in the wastewater and discharges the settled wastewater for further treatment and dispersal to the environment.

Water tight container for the retention of sewage prior to disposal. The tank is typically sized to contained three days of sewage effluent.
An underground tank to collect wastes from homes that are not connected to a municipal sewer system. Waste goes from the home to the tank and is decomposed by bacteria. Solids and dead bacteria settle to the bottom as sludge while the liquid portion flows into the ground through drains. While properly placed and maintained septic systems can effectively treat domestic wastewater, others are a major source of ground water and surface water pollution.
A type of sedimentation tank in which the sludge is retained sufficiently long for the organic content to undergo anaerobic digestion. (When efficient, this equates to secondary treatment.)
A buried, preferably watertight tank designed and constructed to receive and partially treat raw wastewater. The tank separates and retains settleable and floatable solids suspended in the raw wastewater. Settleable solids settle to the bottom to form a sludge layer. Grease and other light materials float to the top to form a scum layer. The removed solids are stored in the tank, where they undergo liquefaction in which organic solids are partially broken down into dissolved fatty acids and gases. Gases generated during liquefaction of the solids are normally vented through the building's plumbing stack vent.
A watertight tank consisting of two chambers used to hold sewage/waste water. While in the tank, the sewage separates into three components, scum which rises to the surface, solids which settle to the bottom, and the remaining liquid called effluent is distributed to the tile bed. Septic tanks can be constructed of a variety of materials including concrete, heavy plastics, coated steel, or fiberglass.
A watertight vault in which sewage is accumulated with the intention of extracting scum, grease, and solids from the liquid without the addition of air and anaerobic digestion of the sewage being established.
A watertight tank that collects wastewater from a home or other facility for treatment. Usually made of fiberglass or concrete and buried underground. A septic system requires bacteria to break down the wastes. Some bacteria is naturally occurring, but septic systems generally work best when bacteria is added to the tank. The normal water flow from sinks, toilets, washing machines, etc. carries the liquid from the tank out to the lateral field, while solids settle to the bottom of the tank. The solids that remain in the tank create a sludge that must be removed (pumped out) periodically. Septic tanks are sized according to the number of people living in the home or using the facility, as well as other features, such as garbage disposals.
a tank, commonly buried, to which all of the wastewaters from the home should flow and in which, primary digestion of the organic matter occurs by anaerobic bacteria; the main part of a septic system where scum and solids accumulate; derived from asepsisfi meaning “putrid decay†or “decay without oxygen.
A type of settlement tank in which the sludge is retained for sufficient time for the organic matter to undergo anaerobic decomposition.
the water tight receptacle designed to receive domestic wastewater and allow the clarified liquids to be discharged into a subsurface soil absorption system.
An tank (usually kept underground) that is used to hold domestic wastes when a sewer line is not available to carry them to a treatment plant. It stores the solid waste until bacteria breaks it down and the relatively clean water is absorbed by the ground.
When public sewers are not available, a property is required to utilize a septic tank system. The system includes hooking up the property's sewage system to a tank that is buried deep in the ground away from the house. The solid organic sewage is collected in the tank where it is decomposed and purified by anaerobic bacteria. Click here to learn more.
Tank that receives wastewater from a building served by a septic system
The first part of a septic system in which sewage settles to the bottom and liquid components are siphoned off the top of the drainage field.
A concrete or steel tank where sewage is reduced to liquid and gases by bacterial action. About half the sewage solids become gases that escape back through the vent stack in the house. The liquids flow from the tank into the ground through a leaching field tile bed.
An underground tank in which sewage from the house is reduced to liquid by bacterial action and drained off.
a plastic or concerete tank used for onite (home) treatment of wastewater; the septic tank collects solids while liquids move on to a drain field where they are treated.
A watertight chamber, which all household wastewater enters for settling and anaerobic digestion of greases and solids. Original tanks were made of asphalt-coated steel. Modern tanks are made of concrete, fiberglass, or plastic. All tanks should have a set of baffles, which are critical to their operation. Most tanks have and inspection hatch ot both the inlet and the outlet and some have a third hatch in between for pumping access. Locations of each of these should be recorded and/or marked. Steel tanks often have one round lid that covers the entire tank. Septic tanks should be pumped every three years or so in normal operation. They should not be treated with any additives and should be protected from receiving any of the harmful chemicals used in many homes and commercial workshops. This includes disinfectants or bleaches, which can kill bacteria in the tank, and solvents, darkroom chemicals, or other materials that could pollute the water supply.
underground receptacle for wastewater from a home. The bacteria in the sewage decopose the organic wastes, and the sludge settles to the bottom of the tank. The effluent flows out of the tank into the ground through drains.
A tank constructed or manufactured to accept sewerage when no mains system is available.
used to hold domestic wastes when a sewer line is not available to carry them to a treatment plant. Part of a rural on-site sewage treatment system.
A buried, preferably watertight tankdesigned and constructed to receive and partiallytreat raw wastewater. The tank separates and retainssettleable and floatable solids suspended in the rawwastewater. Settleable solids settle to the bottom toform a sludge layer. Grease and other light materi-als float to the top to form a scum layer. Theremoved solids are stored in the tank, where theyundergo liquefaction in which organic solids arepartially broken down into dissolved fatty acidsand gases. Gases generated during liquefaction ofthe solids are normally vented through thebuilding’s plumbing stack vent.

A private sewage system holding tank, installed together with a leaching field, that collects sewage and allows the solid waste to settle to the bottom of an area while the liquid particles of the sewage drain into the leaching field area.
A sealed tank buried in a pit in the ground, used for the storage of domestic sewage and waste water in the absence of mains sewers. To conform with building regulations, it must be sited a certain distance from a house, and be lined to an approved standard. It requires regular professional emptying.
A tank in which the solid matter of continuously flowing sewage is disintegrated by bacteria.
a watertight pretreatment receptacle receiving the discharge of sewage from a building sewer or sewers, designed and constructed to permit separation of settleable and floating solids from the liuquid, detention and anaerobic digestion of the organic matter, prior to discharge of the liuquid.
A system used where wastewater collection systems and treatment plants are not available. The system is a settling tank in which settled sludge is in intimate contact with the wastewater flowing through the tank and the organic solids are decomposed by anaerobic bacterial action. Used to treat wastewater and produce an effluent that is usually disposed of by subsurface leaching.

A watertight receptacle that receives the discharge of a building's sanitary drain system or part thereof and is designed and constructed so as to separate solid from the liquid, digest organic matter through a period of detention, and allow the liquids to discharge into the soil outside of the tank through a system of open-joint or perforated piping, or through a seepage pit.
A septic tank also known as a septic system is a small scale sewage treatment system common in areas with no connection to main sewerage pipes. Septic systems are a type of On-Site Sewage Facility (OSSF). In North America approximately 25% of the population relies on septic tanks; this can include suburbs and small towns as well as rural areas.
