The MWRD is supporting leading-edge research in this field to help make algae technology a practical and sustainable approach to nutrient management for urban wastewater treatment plants. During the water treatment process, the greenhouse research facility at the O’Brien WRP employs a technology called revolving algae biofilm reactors ...
The Urban Waste Water Treatment Directive (full title "Council Directive 91/271/EEC of 21 May 1991 concerning urban waste-water treatment") is a European Union directive regarding urban wastewater collection, wastewater treatment and its discharge, as well as the treatment and discharge of "waste water from certain industrial sectors".
The Deer Island Waste Water Treatment Plant, serving the Boston, Massachusetts area, is a typical point source discharger. Point source water pollution comes from discrete conveyances and alters the chemical, biological, and physical characteristics of water. In the United States, it is largely regulated by the Clean Water Act (CWA). [1]
The basic national standard for U.S. municipal treatment plants is the Secondary Treatment Regulation. [2] Most plants in the U.S. must meet this secondary treatment standard. The permit authority (state agency or EPA) can compel a POTW to meet a higher standard, if there are applicable water quality standards for the receiving water body.
Examine the water quality aspects of urban runoff, and a comparison of results across various urban sites; Assess the impact of urban runoff on overall water quality; Implement stormwater management best practices. [1]: iii A major component of the project was an analysis of water samples collected during 2,300 storms in 28 major metropolitan ...
Picture of a wastewater stream In India, wastewater treatment regulations come under three central institutions, the ministries of forest, climate change housing, urban affairs and water. [86] The various water and sanitation policies such as the "National Environment Policy 2006" and "National Sanitation Policy 2008" also lay down wastewater ...
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

Combined Sewer System. The change in the river's water flow was estimated to provide enough treatment-by-dilution for up to a population of three million. [1] However, in 1908, it became clear to the Chicago Sanitary District that the city’s population was continuing to grow and that the population would soon exceed the treatment capacity that the canal offered.
