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

Rainwater Harvesting Rebate Program

Post Oak Savannah GCD offers a rainwater harvesting rebate to promote and encourage collection as a water conservation method. Rainwater harvesting can help reduce peak season pumping demands on our aquifers in the summer months, reduce stormwater runoff, and provide an alternative water supply source that in turn improve water quality and reduce erosion.
For every 1 inch of rainfall 0.6 gallons can be collected for each square foot of collection surface. For example, (2,000 sq. ft. roof) x (0.6 gallons) = 1,200 gallons harvested per 1 inch of rainfall.
