Snowmelt from the Sierra Nevada is the primary source of water for San Francisco. To balance the needs of our growing population with winter snowpack reduced by climate change, water efficiency is essential.
The good news is that saving water saves money and energy too. Both form and function are often improved by fixing leaks and installing high efficiency plumbing appliances. Outdoors, money and resources are stretched with simple measures like mulching, harvesting water in rain barrels, and landscaping with native and climate-adapted plants.
