Momentary System Pressure Loss

On the 13th of October 2016, the City of Iona’s Water System experienced a momentary reduction of water pressure below 20 psi. This pressure loss was caused by a control system malfunction and lasted for a duration of approximately two minutes. The State of Idaho Rules for Public Drinking Water Systems requires any public water system to be capable of providing sufficient water during maximum day demand conditions, including fire flow to maintain a minimum pressure of twenty (20) psi throughout the distribution system, at ground level, as measured at any consumer’s service connection.

Although this situation did not create a risk to public health, as our customers you have a right to know what happened and what we did to correct the situation.

What Should I Do?

There is nothing you need to do at this time. If this was an emergency you would have been notified within twenty four (24) hours with explicit instructions.

What Is Being Done?

Multiple water samples were taken immediately following the pressure loss event to ensure the safety of Iona’s drinking water.

Please contact Public Works Director Zech Prouse with any questions.
