Douglasville-Douglas County Water and Sewer Authority (DDCWSA) received a $300,000 commitment to offer a rebate program to replace inefficient toilets that use more than 1.6 gallons per flush and exist in homes built in 1993 or earlier. It is estimated that toilets can account for one-third of water use in a home. Small funds here have a large impact: eliminating customer leaks not only reduces water demand, but can save the average family nearly $100 per year.
A brief case study of this is available here.
