This work will begin overnight on Sunday, April 30 continuing on a five-day cycle from 10:00 PM to 6:00 AM. Flushing will not take place overnight on Fridays or Saturdays.

This five-day flushing cycle will continue for approximately two months as crews move throughout the distribution system.

What is Water Distribution System Flushing? 

This work involves opening fire hydrants to allow water to flow from fire hydrants at key points throughout the distribution system.

Opening these fire hydrants allow water to flow much faster than normal through the water mains in the area. This fast-moving water clears natural minerals (iron and manganese) that can build up inside pipes. Proactively flushing these pipes helps to ensure that Halifax Water is providing high-quality water to our customers.
