Rainfall which runs off roofs and roads and other surfaces and flows into gutters, streams and waterways where it eventually flows into the bays. This water can carry with it all sorts of contaminants. Some are obvious such as plastic bags or detergents from people washing their cars, others are not so obvious such as nutrients and heavy metals.

the run-off from rainfall events

management system : A system designed to catch, retain, divert, and/or use a sudden influx of water that results from rainfall or snowmelt.

Water, often containing pollutants, that runs off roofs, roads and other urban surfaces and drains directly into waterways

Runoff from a rain storm event, snow melt runoff, and surface runoff and drainage.

The surface water runoff resulting from precipitation falling within a watershed.

That portion of rainfall that does not infiltrate into the soil.

Stormwater is the portion of rainfall that runs off the property and does not soak into the ground.

rainwater which has run off the ground surface, roads, roofs, paved areas etc. and is usually carried away by drains

Rainwater and meltwater running of a surface.

Refers to rainwater as well as water from washing cars, overwatering lawns, and other sources. Stromwater washes down storm drains on the curbs of roads and leads directly into lakes, rivers, and streams untreated. Stormwater can carry pollution directly into our natural water resources.

water that is generated from precipitation, as opposed to groundwater, which exists beneath the land

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.

Rain and water from irrigation, garden hoses, or other activities that can wash materials such as motor oil, paints, fertilizers, and pesticides off of streets, parking lots, yards and landscapes and into the storm drain system.

Rainwater that is collected on roofs, driveways and roads. This water is carried away in a system of stormwater drains that is separate from sewers.

Stormwater runoff, snow melt runoff, surface runoff, and pavement runoff and drainage.

Water derived from a storm event or conveyed through a storm sewer system.

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.

Rainfall that runs off roofs, roads and other surfaces where it flows into gutters, streams, rivers and creeks, and eventually into the bays. This water can carry contaminants such as plastic bags, detergents, nutrients and heavy metals.

Rainwater that enters the storm drain system and empties into rivers, lakes and streams.

Precipitation that is often routed into drain systems in order to prevent flooding.

Water that is generated by rainfall and is often routed into drainage systems in order to prevent flooding.

Runoff from a storm event or surface runoff and drainage.

water that is generated by rainfall, causes runoff and often is routed into drain systems.

Precipitation from rain or snow that accumulates in a natural or man-made watercourse or conveyance system.

Technically, all runoff is stormwater. However, the term "stormwater" is generally used in reference to urban runoff in constructed stormwater drainage systems.

Surface water resulting from rainfall that does not percolate into the ground or evaporate.

Precipitation that accumulates in natural and/or constructed storage and stormwater systems during and immediately following a storm event

runoff from urban areas that is not absorbed into the ground but rather is conveyed to coastal waterways by natural and man-made conduits and drains

Rainfall or other forms of precipitation. Stormwater runoff is the result of stormwater washing across impervious surfaces, carrying with it the pollutants found on streets, parking lots, rooftops, etc. These pollutants end up in streams and rivers. Stormwater runoff contributes from 60 to 80% of total water pollution.

Runoff water resulting from rain. Stormwater collection systems such as roadways and drains return this runoff to waterways and the ocean.

Any surface water that arises from precipitation and enters watercourses (above or below ground) can be termed stormwater. In upper catchments stormwater of high quality is captured for drinking water. In urban areas stormwater is likely to contain contaminants and to be of lower quality.

Water that is generated by rainfall and is often routed into drain systems in urban areas to prevent flooding.

Water that arrives on a site from precipitation, run off from buildings, neighbouring sites, etc. Normally this is collected and channeled into municipal storm sewers.

Rainwater that enters the storm drain system and empties into lakes, rivers, streams or the ocean.

Water off the roads and roof of houses. Must not be connected to sewerage system. Often gets polluted by human urban activities.

Water that directly results from a rainfall event.

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

Rainwater that runs off streets and gutters, enters drains and waterways and is eventually discharged to the sea; in Victoria, stormwater is untreated but may be filtered by traps or wetlands.

Stormwater is a term used to describe water that originates during precipitation events. It may also be used to apply to water that originates with snowmelt. Stormwater that does not soak into the ground becomes surface runoff, which either flows into surface waterways or is channeled into storm sewers.
