High-Efficiency Toilet Residential Rebate Program

Effective July 1, 2018
City of Modesto water customers in single and multi-family homes may be eligible for a rebate when they replace their old high water use toilets. Funding is limited and applications will be accepted on a first come, first served basis. The City reserves the right to terminate this program at any time and for any reason.

Customers are eligible for a $50 rebate with the purchase of qualifying High Efficiency Toilets (HET) of 1.28 gallons per flush or less. The rebate amount may not exceed $150 per City of Modesto water account.

Replacing a high water use toilet with a new HET of 1.28 gpf can save about 38 gallons of water each day. An HET uses 20% less water per flush than ULFT models. Efficiency measures such as replacing water guzzling toilets with the latest in low-flush toilet technology helps ensure the future water supply is adequate and helps maintain low water rates.
