A dairy farmer in Petaluma, California, shows that storm water runoff capture is worth the effort. He has collected 670,000 gallons of water so far this winter enough for 700 cows in his herd for 1 month. Governor Newsom has ordered the state of California to collect storm water runoff from rain storms that happened this year following three dry years.
Researchers say that water runoff is a serious proposition. About 2.5 million people can have enough water for 1 year if the water is collected in southern California and the San Francisco Bay area.
