Picture bathing a garden in this nectar: Instead of letting it run into the street and sewer, you capture it in barrels to use. This practice, known as “rainwater harvesting,” is catching on. “There are a number of reasons to partake in rainwater harvesting, al- A though the most significant benefit is saving water,” Arnie Thompson, Acterra Watershed Project program director, said. Rainwater can be used for everything from watering the lawn to toilet flushing and showering. “In Palo Alto, we use high-quality drinking water from the Hetch Hetchy Reservoir for purposes of irrigation. If you use the water from harvesting, then you’re saving water that would normally come from the domestic water supply.” And, it reduces pollutants in the storm-drain system. Rainwater falling on impervious surfaces such as roofs, driveways and sidewalks slides off along with pollutants and goes into the stormdrain system, ending up in local creeks and ultimately in the San Francisco Bay. Harvesting captures and cleanses the water running off the roof and into a leaf-eater and a flush diverter. Water can then be used for home irrigation, although one shouldn’t drink it unless properly treated, Thompson advised. Harvesting can also reduce the strain on the drain system, potentially reducing flood risk. Strain usually occurs after a big storm, during which the drain system is under pressure because it is taking in the city’s vast amount of (continued on page 39) *>œÊÌœÊ7iiŽÞÊUÊiLÀÕ>ÀÞÊÓx]ÊÓ䣣ÊU Page 37
