Water Distribution Division

Click to learn: WHO IS MY ISO?

A main goal of ours is ensuring each irrigator within the Middle Rio Grande Valley receives equitable and quality service. Irrigation Systems Operators (ISOs) are the main points of contact when it comes to scheduling water with MRGCD. All water deliveries must be scheduled through your respective ISO at least 24 hours in advance. Requested delivery times may not always be available, however with longer notice, up to seven days, the possibly increases when accommodating preferred requests.

ISOs are available to schedule water, by phone, between the hours of 7am and 11am, and 4 pm and 6pm, Monday through Saturday. ISOs can be contacted 24 hours a day for emergencies. If a scheduling call is received outside the designated scheduling period, or the ISO is unable to receive a call during the scheduling period, the ISO will return the call no later than the next call-back window.

For questions or scheduling please call or text message your ISO. Click the ISO Search Tool above to find the ISO in your area. In case an ISO cannot be reached, irrigators may call the appropriate ISO Supervisor, the Water Distribution Manager or the MRGCD General Office for assistance.
