Rainwater harvesting

Learn how to build a beautiful, low-water garden on top of your roof! We’ll show examples from around the world and discuss structural requirements, waterproofing, drainage, salvaged and low-cost materials, soil, plants, and maintenance.

Students will tour the Eco Casita's rain garden, map rainwater flows across the site, and learn how to integrate living roofs with rain barrels and water harvesting basins.

Then we'll finish and plant the Eco Casita’s 100 sq. ft, living roof.

Cost: $30-$100 sliding scale. Work trade available. Limit 12 students!

Location: San Francisco

Participants will divert a rainwater downspout to fill a 660 gallon rainwater-harvesting system by linking recycled barrels together.

An hour long lecture will teach how to design viable and site-appropriate systems that integrate rainwater harvesting, greywater recycling, and water conservation in urban gardens. It will focus on how simple, low-cost rainwater catchment systems can:

*reduce stormwater runoff and sewage overflows

*recharge aquifers

*increase your backyard harvest

Simple, low-cost rainwater catchment systems can increase your backyard
harvest, reduce storm runoff, recharge the aquifer, and lower your water
bill.Students will learn how to design systems that conserve water by integrating
greywater recycling, rainwater harvesting, and water-wise gardens.

In this hands-on workshop, we’ll divert roof runoff through a “daisy
chain” of rain barrels into a series of infiltration basins.

Location: BioFuel Oasis, Berkeley, CA

Learn how to turn your driveway or parking lot into a water source with permeable pavement, diversion swales, infiltration basins, and other water harvesting strategies. Using the Biofuel Oasis as a classroom, participants will map water flow, identify pollutant sources, and design water harvesting earthworks to capture and infiltrate water.
