Some stormwater collection systems aim to simply reduce the amount of stormwater runoff that flows to a nearby waterway. The benefits of these systems include reducing pollution [4] in streams, lakes, and nearshore coastal environments, as well as promoting groundwater recharge. The intended end use of a system will determine the level of ...
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
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 ( infiltrate ) and become groundwater , be stored on depressed land surface in ponds and puddles , evaporate back into the atmosphere, or contribute to surface runoff .
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.
Storm drain grate on a street in Warsaw, Poland Storm drain with its pipe visible beneath it due to construction work. A storm drain, storm sewer (United Kingdom, U.S. and Canada), highway drain, [1] surface water drain/sewer (United Kingdom), or stormwater drain (Australia and New Zealand) is infrastructure designed to drain excess rain and ground water from impervious surfaces such as paved ...
A stormwater detention vault is an underground structure designed to manage excess stormwater runoff on a developed site, often in an urban setting. This type of best management practice may be selected when there is insufficient space on the site to infiltrate the runoff or build a surface facility such as a detention basin or retention basin .
