The California Department of Water Resources (DWR) has two new rebate programs to help Californians replace inefficient toilets and tear out water-guzzling lawns, further conserving water during the state’s historic drought.

The “turf and toilet” rebate program is financed by the Proposition 1 water bond approved by voters in 2014. The program will help carry out Governor Brown’s April 1 Executive Order on drought to further reduce water use in homes by replacing more than 10 million square-feet of lawn and upgrading more than 60,000 water-wasting toilets.

DWR will oversee the two rebate programs, which provide a $100 consumer rebate to replace one old toilet per household and up to $2 per square foot for lawn replacement. Californians can visit www.SaveOurWaterRebates.com to apply for the rebates.
