Rainwater harvesting

Rainwater harvesting is an under-utilized practice in Southern California, in part because of the common misconception that we don't get enough rain to make it viable. However, San Diego County averages about 10 inches of rainfall per year. This may not sound like much, until you consider the effectiveness of rooftop-based rainwater harvesting systems.

Did you know?

A 1000 square foot roof is capable of capturing 600 gallons of rainwater for every 1 inch of rain.

ACTIVE RAINWATER HARVESTING​

The more commonly known practice of using barrels or tanks to collect rainwater is referred to as Active rainwater harvesting. The American Rainwater Catchment Systems Association (ARCSA) defines this as “Rainwater that is collected from roofs and other surfaces into containers and stored for later beneficial use is called active rainwater harvesting”.

PASSIVE RAINWATER HARVESTING

Passive rainwater harvesting utilizes the use of rain gardens and earthworks such as swales, basins or depressions to create low maintenance and cost effective means to capture rainwater. Passive rainwater harvesting is defined by (ARCSA) as “Collecting rainwater and runoff directly for infiltration into the ground without immediate storage in a tank is know as passive rainwater harvesting”.

THOUGHTFUL observation and planning are essential to implementing a proper water harvesting system. We utilize designs that consider storm water as a resource, to retain water on site for the benefit of soils, plants, and habitat rather than allowing it to run off into the storm drain.
Our landscapes have a direct impact on our local bodies of water because whatever flows off our gardens and hardscape surfaces will eventually end up in our rivers, lakes and oceans. In addition to helping to restore watersheds and oceans, installing a water harvesting system will reduce your water bill and your dependence on municipal water while also increasing your landscapes resiliency against drought.
