Best management practices (BMPs) is a term used in the United States and Canada to describe a type of water pollution control. Historically the term has referred to auxiliary pollution controls in the fields of industrial wastewater control and municipal sewage control, while in stormwater management (both urban and rural) and wetland ...
In civil engineering (specifically hydraulic engineering), a hydrodynamic separator (HDS) is a stormwater management device that uses cyclonic separation to control water pollution. They are designed as flow-through structures with a settling or separation unit to remove sediment and other pollutants. [1]
Percolation Trench. A percolation trench, also called an infiltration trench, is a type of best management practice (BMP) that is used to manage stormwater runoff, prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay.
The Storm Water Management Model Climate Adjustment Tool (SWMM-CAT) [10] is a new addition to SWMM5 (December 2014). It is a simple to use software utility that allows future climate change projections to be incorporated into the Storm Water Management Model (SWMM).
A concept that began in Prince George's County, Maryland in 1990, LID began as an alternative to traditional stormwater best management practices (BMPs) installed at construction projects. [6] Officials found that the traditional practices such as detention ponds and retention basins were not cost-effective and the results did not meet water ...
Local governments use a variety of stormwater management techniques to reduce the effects of urban runoff. These techniques, called best management practices for water pollution (BMPs) in some countries, may focus on water quantity control, while others focus on improving water quality, and some perform both functions.

To address the nationwide problem of stormwater pollution, Congress broadened the CWA definition of "point source" in 1987 to include industrial stormwater discharges and municipal separate storm sewer systems ("MS4"). [30] These facilities are required to obtain NPDES permits. This 1987 expansion was promulgated in two phases.
Continuous monitoring and adaptive control (CMAC) is a category of stormwater best management practice that allows for a wider range of operation of detention and retention ponds. CMAC systems typically consist of a water level sensor , an actuated valve , and an internet connection.
