A drywell that receives untreated sanitary waste containing human excreta, which sometimes has an open bottom and/or perforated sides (40 CFR 144.3). Cesspools with the capacity to serve 20 or more persons per day were banned in federal regulations promulgated on December 7, 1999. The construction of new cesspools was immediately banned, and existing large-capacity cesspools must be replaced with sewer connections or onsite wastewater treatment systems by 2005.
A covered watertight tank used for receiving and storing sewage from premises which cannot be connected to the public sewer and where conditions prevent the use of a small sewage treatment works, including a septic tank.
The original type of sewerage system, often still in use inolder homes. They were simply a single hole in the ground loosely blocked up with locally available materials - stone, brick, block, or railroad ties - and capped either with ties covered with a layer of old steel roofing or a cast-in-place concrete lid with a cleanout hole near the center. All household wastewater entered and the liquid portion was absorbed into the ground. When the soil plugged, a new cesspool was added. Wiser installers placed an elbow, or better still, a tee in the outlet pipe from the first cesspool, creating a baffle to hold back the floating greases and scums. In a sense, this created the first type of septic system, because the first cesspool in the line, sealed by its own demise, served as a septic tank and the subsequent tank provided a greater degree of settling and separation of soil-plugging solids and some absorbtion. (Owners often have the first tank pumped out to maintain system operation.)
A covered pit with a perforated lining in the bottom into which raw sewage is discharged: the liquid portion of the sewage is disposed of by seeping or leaching into the surrounding porous soil; the solids, or sludge, are retained in the pit to undergo partial decomposition before occasional or intermittent removal. Cesspools are no longer permitted for waste disposal.
A cesspool is a lined excavation in the ground which recieves the discharges of a drainage system or part thereof, so designed as to retain the organic matter and solids discharging therein, but permitting the liquids to seep through the bottom and sides.
A lined or partially lined excavation or pit for dumping raw household wastewater for natural decomposition and percolation into the soil. Unlike a properly designed Septic System, cesspools do not provide adequate treatment of the wastes and are ILLEGAL!.
