🚒💧 ONWASA customers may notice temporary water discoloration in some areas while several fire departments throughout our service area conduct hydrant flushing, equipment testing, and training activities.

This type of activity is important for maintaining fire protection systems and ensuring hydrants are operating properly but it can occasionally stir up naturally occurring minerals and sediment within the water lines, resulting in discolored water. We appreciate your patience and understanding as these important fire protection activities are completed throughout the area. A flushing guide may be found at www.onwasa.com/flushing

For questions or to report prolonged discoloration, please contact us via our website or at 910-455-0722.
