Profiled in the June 2012 design issue of San Francisco Magazine, the Geoffrey Butler home, located in Mill Valley, saves up to 61,000 gallons of water per year.

A 4-HOG installation (hidden under the deck) converts showers into lawn water, and an additional 15 HOG tanks are used to flush the toilet in the 5-person home for up to 8 months out of the year.
How does the HOG modular rainwater catchment system work in this Mill Valley home?
