Welcome to iEfficient.com

The Inland Empire’s go-to source for information on water-use efficiency. Here you will find tips for increasing conservation, details on water- and money-saving rebates and, most importantly, ways to eliminate water waste. We’re glad you could join us on this journey toward a more sustainable future.


For the first time in its near 50-year history, overflow water at Lake Oroville Reservoir is sent down an emergency spillway.  Damage in the concrete in early February reduced dam releases, resulting in high storm runoff pouring into the reservoir and causing the overflow.  Lake Oroville is the heart of the State Water Project which sends water from Northern to Southern California. State water managers are monitoring the situation closely to evaluate further concrete damage and are already estimating repair costs to top $200 million, a bill that could go directly to the rate payers of Southern California.  For information information regarding Lake Oroville and the State Water Project, visit cawaterfix.com.

Winter Water Saving Tips

Loosen compacted soil by tilling or raking; ground that has dried out will repel water.

Leave your lawns a little longer; longer blades of grass encourage deeper roots which require less frequent watering.

Turn off automatic sprinkler systems; shorter days and longer nights require less outdoor watering.

Place porous materials around your garden, like gravel and pebbles, to let water seep through into the ground to your plants roots.

Use rain barrels to capture water for later use; check your local water agency for rebates.

Find and fix leaks; dye tabs are a quick and simple way to check for leaky pipes.

install a high-efficiency toilet; check your local water agency for rebates.

Sweep driveways and patios clean rather than hosing off.




Together we can help protect our most precious natural resource and set an example for other regions throughout California.
