Rainwater and snowmelt that runs off impervious surfaces rather than infiltrate into the soil Through a drainage system of underground pipes, stormwater carries nutrients, fine soils, plant debris, drippings from vehicles, and other substances from the drainage basin Most of Eagan lakes, ponds, and wetlands are connected to the stormwater system
That portion of precipitation that does not naturally percolate into the ground or evaporate, but flows via overland flow, interflow, channels or pipes into a defined surface water channel or a constructed infiltration facility
the water discharged as a result of rainwater Specific problems caused by stormwater run-off include pollution of our surface and ground waters, as well as flooding
water collected in a system of pipes which drain roads and industrial or trade premises Stormwater may contain contaminants present on drained surfaces
Rainwater which runs off the land, frequently carrying various forms of pollution such as rubbish, animal droppings and dissolved chemicals This untreated water is carried in stormwater channels and discharged directly into creeks, rivers, the harbour and the ocean
Rain, which runs off roads, yards and roofs and down gutters into stormwater grates Stormwater picks up silt and other contaminants as it runs over these surfaces It is piped/runs untreated into streams and harbours More info
The runoff from rainstorms Stormwater contains the highest amount of pollutants early in a storm; the first one inch of runoff, or "first flush," contains over eighty percent of the total pollutant load
Water from rain or melting snow Many communities are concerned about the management of stormwater in developed areas because the amount of impervious surface has increased, thus reducing the area where rain water may naturally infiltrate the soil
