WATER FOR TOMORROW”
“WE MAKE IT EASY GOING GREEN”!
Monte Sereno, CA – The California drought may appear to have softened because of the last batch of rains, but Monte Sereno resident Jerry Block isn’t having second thoughts at all about having one of the largest rain collection systems in the Santa Clara Valley recently installed in his back yard.
You may wonder why he installed this system when he’s only saving a few hundred dollars a year. Jerry feels it’s all about being sustainable and preparing for the unknown.
“What if there is an earthquake and what if the drought continues?” says Jerry, “At least I will have water for my family and neighbors. Rainwater can also be used for fire suppression, irrigation, washing your car and even for keeping your swimming pool filled. “
“The overall water supply situation has not improved enough to make up for the two previous dry years and low reservoir conditions,” says DWR Director Lester Snow. “Water storage is about five million acre feet below average.”
Jerry is being sustainable about his efforts with his newly installed rain harvesting system because it saves the water agency electricity from not having to pump 20,000 gallons of water to his home anymore.
Collecting this much rainwater significantly reduces stormwater runoff and erosion problems. That’s 20,000 gallons less rainwater that could get contaminated by the time it gets to a stream or an underground aquifer. With the craze of the Victory Gardens, as popularized by Michelle Obama, rainwater catchment helps assure that water will be available for growing home gardens during hot summer months.
“Most people don’t really understand the sustainable reasons for having a rain harvesting system installed,” comments John. “The return on investment may never come, but having a rainwater supply is more than valuable, it’s responsible.”
Fremont based company Rain Harvesting Systems installed four 5,000-gallon rainwater tanks to achieve the 20,000 gallon capacity. Gutterglove Gutterguard was used on the roof gutters for filtering out all the leaves, pine needless and sand from the four rain tanks.
Tim Pope, president of the American Rainwater Catchment Systems Association (ARCSA), sees a growing demand for information about collecting rainwater.
“Rain harvesting is growing tremendously in the United States, especially in California,” said Pope. “California seems to wait for a catastrophe (drought) before it goes after a cause like collecting rainwater.”
These are just a few of the ever growing rainwater harvesting projects that are spread throughout the United States. The diversity of above and below ground installations is vast.
