Stormwater Treatment Plants
Stormwater Treatment Overview
Stormwater treatment is the process of capturing pollutants and contaminants from surface water runoff before they reach a watercourse or body of water such as a river, lake or ocean. The process improves stormwater runoff quality, reduces runoff volume, reduces runoff peak flow, or any combination of the above.

Stormwater treatment is provided through physical, chemical and biological processes that are discussed in the Water Treatment and Wastewater Treatment application notes. Most municipal stormwater control programs regulate stormwater discharges from three potential sources: municipal separate storm sewer systems, construction activities, and industrial activities. Operators of these sources might be required to obtain an environmental permit before they can discharge stormwater.
Stormwater may involve elements of both Water and Wastewater Treatment. Depending upon the topography lift pumps / transfer pumps may be basins are often used to control storm runoff. Depending upon the criticality of flow, rakes and screens may be necessary to maintain flow. The rotating machines used in Water and Wastewater Treatment are similar to the machines used to handle Stormwater. The monitoring recommendations for the rotating machines used to handle Stormwater are the same as used for Water and Wastewater Treatment.
Water Treatment Plants treat water to make it safe for human consumption and other uses.
Wastewater Treatment Plants clean sewage and water so that they can be repurposed for our use.
Pumps play a vital role in vibration monitoring in water and wastewater treatment plants.
