Rainwater Harvesting 101 (Fairfax)

3rd December 2016 @ 10:00 am - 4:00 pm

This workshop is hosted by Sustainable Fairfax.

Rainwater Harvesting 101

Saturday, December 3, 10am-4pm

Learn to install rainwater harvesting systems in this hands-on workshop taught by experienced instructors from Greywater Action

In this workshop we will  install two types of rainwater harvesting systems:

1) a “dry system” with the downspout flowing directly into a 55 gallon barrel located next to a building
2) a “wet system” that allows rainwater storage to be located  away from a building—the rain will be piped from the gutter, under a path, and over to where it rises naturally into a large cistern.

We will also focus on beneficial “secondary use” of the overflow water from the barrel and cistern, directing it to infiltration in the garden rather than to the storm drain.

You will leave knowing how to calculate the amount of rainwater you can capture from your own roof, and have an idea of the types of storage that are available—so you’ll be all set to design your own system!

The workshop will take place at the Bragman residence in the Cascade neighborhood of Fairfax.  Larry Bragman is our Marin Municipal Water District representative (address to be provided following registration).

Instructors: Christina Bertea and Natalie Kilmer, Greywater Action

“Dry System”: rain flows directly into a barrel:


“Wet System”:  rain flows under a  pathway and back up into a cistern:
