Stormwater collection is widely practiced for purposes of urban runoff and flood mitigation as well. [6] Treatment Dissolved Air Floatation Treatment at the Santa Monica Urban Runoff Recycling Facility Stormwater treatment is the greatest challenge for stormwater harvesting. Water treatment processes depend on the intended end use and the ...
Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. [1] Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water.
Erosion control is the practice of preventing or controlling wind or water erosion in agriculture, land development, coastal areas, river banks and construction. Effective erosion controls handle surface runoff and are important techniques in preventing water pollution, soil loss, wildlife habitat loss and human property loss.
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.

The surface layer of the LID receives both direct rainfall and runon from other areas. It loses water through infiltration into the soil layer below it, by evapotranspiration (ET) of any water stored in depression storage and vegetative capture, and by any surface runoff that might occur.
Rainwater harvesting (RWH) is the process of collecting and storing rainwater rather than letting it run off. Rainwater harvesting systems are increasingly becoming an integral part of the sustainable rainwater management "toolkit" [5] and are widely used in homes, home-scale projects, schools and hospitals for a variety of purposes including watering gardens, livestock, [6] irrigation, home ...
Surface runoff consists of building roof runoff, parking lot runoff and overland flow from properties to the north of the project site. A total of two lineal miles of bioswale was designed into the project. The purpose of the bioswale was to minimize runoff contaminants from entering Sonoma Creek. The bioswale channel is grass-lined and nearly ...
To control pollutants found in surface runoff, permeable paving surfaces capture the stormwater in the soil or aggregate base below the road or pathway, and subsequently treat the runoff via percolation, which allows water to infiltrate, supporting groundwater recharge or contain the stormwater to be released back into municipal stormwater ...
