    WHAT IS URBAN STORM WATER?

    ISA

    Stormwater refers to the water (either rain or snowmelt) that flows over the land and heads downhill towards the nearest stream or ditch. In a natural setting, most rainfall or snowmelt would soak into the soil, the soil filtering out sediment and pollutants. Cities and towns have many "impervious surfaces", such as driveways, roads, sidewalks, parking lots, and rooftops, that water can't penetrate. Instead, these impervious surfaces collect the stormwater, as well as oil and other toxic chemicals from parking lots and houses, and sends it straight to storm drains which drain directly into your local lake or stream.


    WHY CARE ABOUT STORM WATER?

    Water in the West is a precious commodity as our desert landscape doesn't provide us with very much water. The Intermountain West is also experiencing some of the fastest urban growth in the United States, which is causing an increase in water use, especially for watering lawns and gardens. This increase use has taken strong blows at the local environment. The construction as well as increase in impervious surfaces has also taken a heavy toll on the water quality that we rely on. The desert climate has exacerbated the issue as during dry spells, toxic chemicals accumulate on impervious surfaces, then rush into the local water bodies in high concentrations through storm drains.

    ADDITIONAL RESOURCES

    Human caused factors are very influential on stormwater quality in urban areas. We do so much that changes the natural flow of water and we add many chemicals that are not only toxic to the local wildlife, but also to ourselves. A common misconception is that storm drains first drain water to a treatment plant, but since that's not usually true it is important that we do what we can to maintain our stormwater clean. Below are things that we do that impact stormwater quality as well as things you can do to limit your impacts on stormwater quality.
