Effluent is wastewater from sewers or industrial outfalls that flows directly into surface waters, either untreated or after being treated at a facility. [1] The term has slightly different meanings in certain contexts, and may contain various pollutants depending on the source.
Effluent pumping sewers have small diameter pipes that follow the contour of the land and are only buried a metre or two underground. While an effluent sewer can use gravity to move waste, the ability to move waste with a pressure system can be a big advantage in places where a gravity system is impractical.
A tributary, [1] or an affluent, [2] is a stream or river that flows into a larger stream (main stem or "parent"), river, or a lake. [3] A tributary does not flow directly into a sea or ocean . [ 4 ]
It thus converts it into an effluent that can be returned to the water cycle. Once back in the water cycle, the effluent creates an acceptable impact on the environment. It is also possible to reuse it. This process is called water reclamation. [1] The treatment process takes place in a wastewater treatment plant.
Tributary or affluent: a stream or river that flows into the main stem (or parent) river or a lake. Vernal pool: a shallow, natural depression in level ground, with no permanent above-ground outlet, that holds water seasonally. Wadi: a usually-dry creek bed or gulch that temporarily fills with water after a heavy rain, or seasonally
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. [2]
Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment.
The effluent limitations for the Construction and Development category are narrative in format and do not specify numeric pollutant limits. The requirements consist of erosion controls and sediment controls , soil stabilization practices and pollution prevention practices (such as minimizing exposure of building materials, pesticides and other ...
