Selection or a particular sampler type depends on the type of analysis to be performed (e.g. ambient water quality or wastewater), the type of water source (e.g. a lake or pond, small stream or large river, coastal waters or deep ocean) and other factors such as ambient environmental conditions (e.g. collection of stormwater during a rain event ...
Stormwater harvesting or stormwater reuse is the collection, accumulation, treatment or purification, and storage of stormwater for its eventual reuse. While rainwater harvesting collects precipitation primarily from rooftops, stormwater harvesting deals with collection of runoff from creeks, gullies, ephemeral streams and underground conveyance.
Industrial stormwater is runoff from precipitation (rain, snow, sleet, freezing rain, or hail) that lands on industrial sites (e.g. manufacturing facilities, mines, airports). This runoff is often polluted by materials that are handled or stored on the sites, and the facilities are subject to regulations to control the discharges.
hydraulic and water quality analysis of storm, sanitary, and combined sewer systems; master planning of sewer collection systems and urban watersheds; system evaluations associated with USEPA's regulations including NPDES permits, CMOM, and TMDL; 1D and 2D (surface ponding) predictions of flood levels and flooding volume
Recently completed infiltration basin for stormwater collection. An infiltration basin (or recharge basin) is a form of engineered sump [1] or percolation pond [2] that is used to manage stormwater runoff, prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay.
Stormwater, also written storm water, is water that originates from precipitation , including heavy rain and meltwater from hail and snow. Stormwater can soak into the soil and become groundwater, be stored on depressed land surface in ponds and puddles, evaporate back into the atmosphere, or contribute to surface runoff.
A raw water collection point (above or below ground) where the water accumulates, such as a lake, a river, or groundwater from an underground aquifer. Raw water may be transferred using uncovered ground-level aqueducts, covered tunnels, or underground water pipes to water purification facilities. Water purification facilities.
A rainwater catchment or collection (also known as "rainwater harvesting") system can yield 1,000 litres (260 US gal) of water from 1 cm (0.4 in) of rain on a 100 m 2 (1,100 sq ft) roof. Rainwater tanks are installed to make use of rain water for later use, reduce mains water use for economic or environmental reasons, and aid self-sufficiency .
