Stormwater Management (Rainwater Harvesting)

Rainwater harvesting offers a small-scale best management practice to reduce stormwater runoff and the problems associated with it.

By harvesting the rainfall and storing it, you can slowly release the water back into the soil, either by irrigation or direct application. The water then moves into the groundwater table, providing a steady supply of water to local streams and rivers. Impervious surfaces such as driveways, sidewalks and streets block rainfall and other precipitation from infiltrating naturally into the ground, leading to even more stormwater and potential pollutant runoff. 

Movement of this stormwater across the soil causes erosion. It can also carry and deposit untreated pollutants, such as sediment, nutrients and pesticides, into surface-water bodies

    30,000 Gallon Modular, Underground Rainwater Harvesting System
    Watch the entire installation process of a 30,000 gallon modular, underground rainwater collection system. These modular units are constructed onsite, wrapped with layers of geotextile fabric and a impervious liner, and then covered. This system can be stacked up to 5 units tall which is 7.5'. We installed a submersible pump in the storage volume and connected it to a pump start relay controller so the pump will only turn on when the irrigation controller signals the pump start relay. This system is collecting from roughly 10,000 square feet of collection surface and has the capacity to collect about 200,000 gallons of rainwater per year.
