No Water Wasted
Using water wisely helps ensure our future water supply security. Rainfall in late 2021 replenished our local reservoirs, but there’s no way to know for sure what rainfall amounts will look like in years to come. It’s probable that severe dry conditions will recur, continuing to threaten our water supply. Therefore, we encourage our customers to eliminate water waste wherever possible and help preserve this precious resource. We have programs, education, and cost-effective ways to help you.
