Rainwater harvesting is the capture, diversion and storage of rainwater for later use. The District offers a rainwater harvesting rebate to encourage conservation of groundwater through the capture and use of rainwater.

Program Goals

  • to encourage rainwater harvesting to promote water conservation within the District,
  • to promote and adopt Best Management Practices maximizing the effectiveness of integrated rainwater harvesting systems, and
  • to offer workshops on rainwater harvesting.

For every square foot of a collection surface, you can get about 0.6 gallons of water for every 1″ of rainfall. In other words, every 2,000 square feet of collection surface generates 1,200 gallons of water. Harvesting rainwater reduces dependency on groundwater in landscapes, improves soil and plants with higher water quality, and reduces on-site flooding and pollution from stormwater.

Upcoming Workshops

Reminder! To qualify for the rebate, you must complete a Rainwater Harvesting 101 course first.

Check back here for our next Rainwater Harvest Class, coming soon.
