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 ...
Sediment-laden stormwater is collected and or pumped, and a chemical flocculant is added to aide in clarification. Types of flocculant include; Natural Polymers: Derived from natural sources, such as starch, chitosan, and guar gum.
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. It is a shallow excavated trench filled with gravel or crushed stone that is designed to infiltrate stormwater though permeable ...
"California must continue to invest in water management strategies like stormwater capture, groundwater recharge and recycled water to ensure that our water supply remains safe and reliable and to ...

The section requires states to identify water bodies that cannot meet water-quality standards without control of nonpoint sources. The states must then identify best management practices (BMPs) and measures for those impaired sources, along with an implementation plan. The EPA approves these plans, and if a state fails to develop a plan, the ...
[1] [13] [30] [31] Structural BMPs are defined as the components of the drainage pathway between the source of runoff and a stormwater discharge location that affect the volume, timing, or quality of runoff. SELDM uses a simple stochastic statistical model of BMP performance to develop planning-level estimates of runoff-event characteristics.
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.
