The ECUA water system will undergo system-wide testing during the week of September 19 – 23, for the purpose of conducting a fire protection capability evaluation by the Insurance Services Office (ISO).  The ISO evaluation of the water system will entail pressure and flow testing at fire hydrants throughout the ECUA water service area.  These tests have the potential to temporarily impact small segments of the service area, possibly resulting in isolated and/or short-term cases of lower-than-normal water pressure.  The potential also exists for the appearance of discolored water for brief periods in areas where the testing will be conducted.  ECUA crews will be on stand-by in the test areas to conduct system flushing to minimize any of these potential disruptions to ECUA customers.

The ISO testing locations are throughout the system, so it is not possible to identify specific areas that may be impacted.  However, the testing plan will commence on Monday, September 19 in the southwest portion of Escambia County.  The testing program will progress eastward and northward through the week, with the expected completion of the tests by Friday, September 23.

The ISO testing is part of a national program that serves insurance companies, fire departments, and insurance regulators through the provision of information related to risk.  ISO will analyze the information from the tests and assign a Public Protection Classification number, which indicates the water system’s fire-suppression capability.  This information is used in the pricing of homeowner and commercial property insurance.

Please be assured that ECUA is committed to minimizing the potential for any inconvenience related to the ISO system evaluation.  If you experience any on-going problems related to the hydrant testing during the week of September 19, please contact ECUA Customer Service at 476-0480, or e-mail us at
