Why Sustainable Stormwater Management?

The reasons range from environmental to economic.

Here are just a few:

  • Stormwater runs off impervious surfaces (such as roofs and paved areas) instead of soaking into the ground. Conventional stormwater management directs runoff into drains and pipes that carry it offsite and eventually discharge it into a river or stream. This approach has a number of harmful effects:
  • Impervious areas generate large volumes of runoff relatively quickly. The increased volume and speed of the runoff can cause flooding and erosion, destroy natural habitat, and contribute to combined sewer overflows (CSOs).
  • The runoff picks up a variety of pollutants including oil, pesticides, metals, chemicals, and sediment that harm water quality and fish habitat.
  • To Reduce Energy Demands - Water-related energy consumption accounts for nearly 20% of the cost of electricity. One inch of rain falling on 1,000 square feet of rooftop produces more than 600 gallons of water. If every building owner replaced this amount of potable water with captured rain water, energy consumption would be greatly reduced.
  • To Recharge Underground Aquifers - Forty percent of Southern California‚Äôs drinking water comes from groundwater supplies. Harvesting rain water and allowing it to infiltrate into the ground replenishes underground aquifers.
