Sequence of reclamation from left: raw sewage, sewage treatment plant effluent, and finally reclaimed water (after several treatment steps). Water reclamation is the process of converting municipal wastewater or sewage and industrial wastewater into water that can be reused for a variety of purposes .
Water cascade analysis (WCA) is a technique to calculate the minimum flowrate target for feedwater and wastewater for continuous water-using processes. [ 1 ] Principle
The Oregon Water Resources Department (WRD) is the chief regulatory agency of the government of the U.S. state of Oregon responsible for management of all surface and ground water in the state, which by statute belongs to the public. The department’s primary activities include protection of existing water rights, facilitation of voluntary ...
After treatment, the effluent may be returned to surface water or reused as irrigation water (or reclaimed water) if the effluent meets the required effluent standards (e.g. sufficiently low levels of pathogens). Waste stabilization ponds involve natural treatment processes which take time because removal rates are slow.
Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. [1] Recharge occurs both naturally (through the water cycle) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and/or reclaimed water is routed to the subsurface.
The following year, the Oregon Watershed Enhancement Board replaced GWEB, [7] and expanded the five member board with six public members. [9] Passage of Measure 76 in Oregon's 2010 General Election continued lottery funding for parks, beaches, wildlife habitat, watershed protection beyond 2014 and modified the funding process. [10]
The tanks have a “flow through” system, with raw wastewater (influent) coming in at one end and treated water (effluent) flowing out the other. In systems with multiple tanks, while one tank is in settle/decant mode the other is aerating and filling. In some systems, tanks contain a section known as the bio-selector, which consists of a ...
