Rainwater harvesting

Water is a precious resource. With less rain and increasing temperatures leading to longer fire seasons and more limited water supplies, we need to use water wisely in our Golden State.

Every time it rains, a shocking amount of water falling on roofs, parking lots, streets, and other hard surfaces flows away into storm drains and out towards the ocean. We have built our environments to shed water off, rather than welcome it back into the ground where it belongs.




By collecting the rainwater before it flows away, we can make it available to our plants and animal neighbors, and help it to infiltrate directly into the soil of our landscapes like it would in nature. This helps regenerate our local groundwater supplies.
