Spill Notification Procedures

The Maricopa County Environmental Services Department must be notified immediately by the operator when a wastewater or reclaimed water spill occurs. A Spill Notification Form must be filled out and sent by facsimile to 602-506-6925 or emailed to the Water and Wastewater Treatment Program.

During Business Hours


If a spill occurs during normal business hours (Monday - Friday, 8 a.m. - 5 p.m.), and the spill is a critical spill follow-up your email facsimile notification with a telephone call to the Water and Wastewater Treatment Program.

After Business Hours


If a spill occurs after normal business hours or on a holiday, and the spill is a critical spill please follow-up your fax or email notification with a telephone call to the MCESD's Call Center (Complaint Line) at 602-506-6616. Navigate through voicemail menus 1 and 8 and then leave a message with your name, utility name, callback telephone number, details about the spill and identify the spill as a critical spill. The on-call MCESD staff member should telephone you back within 20 minutes. The on-call MCESD staff member will assess what action(s) may be required in response to the spill.

Spills located on private property and not a result of the failure of the utility's infrastructure should be reported to the Call Center. A Spill Notification Report does not need to be submitted for this case.

A Spill Reporting Decision Tree Diagram is available to assist in understanding when a Spill Notification Report should be submitted.
