Understanding Your Water Use


Californians use on average 196 gallons of water per day. An essential first step to conserve in your home, business, or other facility is to understand where you use water. 

Residential users can follow simple steps to determine how and where water is used on their property, and find information, resources, and tools to save water. Commercial, industrial and multi-family properties can find helpful resources and best management practices to save water. Additionally, find resources to address leaks and understand your water bill, as well as how to request guides to conserve water.
