    Fun Fact!

    The City of Kalamazoo Wastewater Treatment Plant currently treats on average about 26 million gallons per day!

    Trees play in important roll in the water cycle by removing certain pollutants, stabilizing soils, absorbing rainwater and preventing erosion. Visit Releaf Michigan for more information.

    Kalamazoo Watershed - Public Responsibility & Stewardship

    Learn how to Protect Your Stormwater

    Water is constantly moving through the water cycle. It is important to remember that human activities affect the water cycle in various ways.:

    1. The removal of ground water & surface water for potable (drinking water)water sources

    2. Water is used for irrigation and industrial processes

    3. Damming rivers

    4. Household water usage

    5. Creating impermeable (does not allow water to flow through) surfaces, likeroads and parking lots

    6. Deforestation

    Human Impact on the Water Cycle

    Precipitation is rain, snow or sleet. About 10% of precipitation that falls runs over the ground to become stormwater

    stormwater sewer systems are built to help manage stormwater in urbanized areas. In the Kalamazoo area municipalities have separate stormwater sewer systems, so those stormwater sewers flow directly to local surface water bodies

    Surface water includes local lakes, rivers and streams and above ground water bodies.

    Stormwater, or precipitation (rain, snow and sleet), falls on the ground, about 10% runs over the ground and collects in surface water, and about 25% infiltrates the ground to become groundwater. Surface water is water held in lakes, rivers, streams and other above ground water bodies. Groundwater is water that is held in the ground between particles of sand and gravel. In Kalamazoo area, all our drinking water supply comes from groundwater. Drinking (potable) water is groundwater that has been pumped from the ground, treated at a local water treatment station, then delivered to our homes and businesses. That drinking (potable) water gets turned into wastewater when used by people or processes. Wastewater treatment plants are designed to remove contaminates before returning the treated water to the Kalamazoo River. Households, industry, and other human activities all have potential to become sources of contamination to the water cycle.

    Mission Statement

    The Kalamazoo Stormwater Working Group (KSWG) is a collaborative effort of outreach and education for our interconnected Municipal Separate Storm Sewer Systems (or MS4s) in the Kalamazoo County area. Rain falls and snow melts across hard and impervious surfaces that do not allow water to soak into the ground. The water flows to storm sewers or catch basins which direct it to a natural surface water body such as a wetland, river, pond or lake. Stormwater runoff carries salts, grass clippings, sediment, fertilizer, oils, pet waste, and other material left on driveways and sidewalks into the catch basins, and unfortunately, they eventually drain to our natural water bodies. KSWG partners work together to protect against harmful discharges to the Kalamazoo River and its tributaries.
