A level spreader is an erosion control device designed to reduce water pollution by mitigating the impact of high-velocity stormwater surface runoff. It is used both on construction sites and for permanent applications such as drainage for roads and highways .
Combined sewer outflow into the Anacostia River in Washington, D.C. Ratcliff Beach CSO discharges into the River Thames in London [7]. These relief structures, called "storm-water regulators" (in American English - or "combined sewer overflows" in British English) are constructed in combined sewer systems to divert flows in excess of the peak design flow of the sewage treatment plant.

The Solid Waste Authority of Central Ohio (SWACO) was established by the Ohio General Assembly in 1989 as part of Ohio House Bill 592, which created Ohio’s current solid waste management planning and regulatory programs. [1] [2] SWACO is a government-run entity responsible for the safe and sanitary management of all solid waste within its ...
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.

Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to channel runoff (or stream flow). It occurs when excess rainwater , stormwater , meltwater , or other sources, can no longer sufficiently rapidly infiltrate in the soil .
For typical wastewater bills, customers in Rate Zone 1 would see a decrease from $105.18 to $100.08 (-4.8%) on 3,122 gallons. Changes in other zones would range from the same 4.8% decrease to an ...
This depth is converted to a flow rate according to a theoretical formula of the form = where is the flow rate, is a constant, is the water level, and is an exponent which varies with the device used; or it is converted according to empirically derived level/flow data points (a "flow curve"). The flow rate can then be integrated over time into ...
Jul. 12—The City of Springfield is planning to begin this fall a $6.5 million project that would replace the pumps at its Wastewater Treatment Plant on Dayton Road. The primary effluent pumps ...
