A small-scale watertight treatment system for domestic sewage in which the flow is slowed to allow sedimentation and sludge digestion by bacteria to take place
A sewage settling tank in which part of the sewage is converted into gas and sludge before the remaining waste is discharged by gravity into a leaching bed underground
a tank used to detain domestic wastes to allow the settling of solids prior to distribution to a leach field for soil absorption Septic tanks are used when a sewer line is not available to carry them to a treatment plant A settling tank in which settled sludge is in immediate contact with sewage flowing through the tank, and wherein solids are decomposed by anaerobic bacterial action
An underground tank into which a sanitary sewer drains from a building The sewage is held until bacterial action changes the solids into liquids or gasses, which are then released into the ground
A septic tank is an underground tank where faeces, urine, and other waste matter is made harmless using bacteria. A sewage-disposal tank in which a continuous flow of waste material is decomposed by anaerobic bacteria. a large container under the ground, for holding human waste from toilets
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 sewage settling tank intended to retain the sludge in immediate contact with the sewage flowing through the tank for a sufficient period to secure satisfactory decomposition of organic sludge solids 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
An underground storage tank for wastes from homes not connected to a sewer line Waste goes directly from the home to the tank Settleable solids Those suspended solids in wastewater that will settle over a certain period of time and are removed in that way Sewage Waste fluid in a sewer system
A tank used to process small quantities of domestic sewage Solid material settles out and is partially degraded by anaerobic bacteria as sewage slowly flows through the tank The outflow is further treated or dispersed in aerobic soil (See 663)
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
A watertight, accessible, covered receptacle designed and constructed to receive sewage in which two processes take place; settling of the solids, and the digestion of some of the accumulated solids by anaerobic action
Holding tank placed underground for treatment of wastewater from a residence Bacteria in the tank are used to decompose organic wastes The tank then releases the effluent into the surrounding ground through a number of drainage pipes
Tank 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 tank buried in the ground where household sewage is gradually decomposed by bacteria Most houses that are not hooked to a sewer line flush waste into a septic tank
A tank (usually concrete) on a property into which raw sewage is discharged The sewage stays in the septic tank long enough for all solids to decay and liquid is drained off to an attached leach bed for the purpose of purifying the liquid
A sewage settling tank in which part of the sewage is converted into gas and liquids before the remaining waste is discharged by gravity into a leaching bed underground
