Drip Irrigation Rebate Program

City of Modesto water customers may be eligible for a rebate when they convert their existing traditional sprinkler system to drip irrigation. The rebate amount may not exceed $1,000 per City of Modesto water account. 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.

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