I am pleased to be amongst the leaders of Rain Water Harvesting in Southern California. Please take a moment and review part of my portfolio of completed projects.
Check it out here.
Please view The Cycle of Insanity video. When I show people this video and explain how much water they can collect their jaws drop. The way we manage our resources is insane. Harvesting rainwater is an easy and realistic way to conserve water in Los Angeles. There is plenty of rain. If one thousand feet of roof area were collected in Los Angeles that would yield 8,700 gallons per year with our average of 14" per year.
Rain water harvesting combined with grey water systems and Xeriscape Gardening can reduce outdoor watering to zero.

Number geeks and grid techs may enjoy this, but when I meet with a client the first thing I ascertain is how much space they have for above ground storage. Below ground is an option, but generally costs triple and involves permits from the government. Sometimes we can capture waste water from the clothes washer or water filters ( gray water ) and run that into the same cisterns that collect the rainwater and run a line back into the house to power a toilet.
One of those questions we must ask ourselves is why are we flushing human waste down the drain with potable water?
Saving Clean Water For Drinking
You can easily find a water tank on the web today made for agricultural or commercial customers. These tanks are generally too large for residential use and typically come in black, white and dark green. Bushman specializes in slimline tanks that fit under the eaves of the house and come in over six color choices.
Alternatively you can pick-up a rain barrel at the local nursery. While these may look great under a downpipe in your garden, they typically store no more than 60 gallons, which is inadequate for most garden sizes. We recommend a minimum of 300 gallons of storage, purpose built to collect and store clean rainwater. Also beware of recycling old plastic containers to rain barrels as they may have been used to transport harsh chemicals for their original purpose and could leech poorer quality plastic.
Because of contamination on the roof the first volume of rain should be diverted from the storage tank.
