Recent Water Quality Event in Alameda Point Underscores Importance of Routine Inspections

Posted on September 28, 2017 at 2:32 PM by Emma Detwiler

You may have seen headlines in the news recently about a water quality event in Alameda Point that caused residents to temporarily stop using tap water for drinking, cooking and bathing.

Alameda’s acting director of public works Liam Garland explained that an irrigation line, fed by a well in Alameda Point, had a cross connection with nearby water pipes. At the cross connection there was a backflow preventer device that failed, allowing irrigation water to enter the drinking water system.

Here at MMWD we are always working to prevent a similar event from occurring. MMWD has an extensive backflow prevention program including staff that work with our customers to ensure their backflow prevention assemblies are routinely inspected, and any issues promptly addressed.

The recent events in Alameda Point underscore the importance of this program, and the work being done to ensure the safety of our public water supply.
