Drip Irrigation Rebate Program

City of Modesto water customers may be eligible for a rebate when they convert their existing overhead spray system to Drip Irrigation or install a Drip Irrigation system in an existing garden bed. 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.

Note: Customers who install qualifying Drip Irrigation products are eligible for a rebate in the amount of $0.25 per square foot for a maximum of 2,000 square feet. The rebate amount may not exceed $500 per City of Modesto water account.

Drip Irrigation eliminates over-watering problems by applying water only where it is needed, with less runoff and less evaporation. The uniform application of water from Drip Irrigation systems can achieve high water savings.
