Maintenance & Flushing of Hydrants

The flushing of the hydrants is usually done once a year. Although this appears to be a hydrant-based activity, the purpose is to flush sedimentation from the water mains. This is normally done by opening all the hydrants at the ends of the mains and usually takes 2 to 3 weeks.

Our staff performs the maintenance and replacement of public hydrants. All of our hydrants have automatic drains, which drain the barrel after use to prevent freezing and the accumulation of stagnant water. Occasionally these do not work and require repair. This occasionally causes hydrants to leak. The majority of hydrant replacements are done by our staff. The exceptions are those cases where hydrants are damaged by vehicle collisions. These damaged hydrants are replaced by a contractor at the expense of the driver's insurance company. Our staff also paints the public hydrants as weather permits. Painting is an ongoing operation.
