Sewer Main Cleaning - Fall 2018

The  Public Works Water/Wastewater Department will begin sewer main cleaning in the North end of Rockwood beginning on Landrex Street and will move south to Highway 7.

Cleaning will begin Tuesday September 11, 2018 and will continue until the North end is completed (early October).  Hours will be between 7:30 a.m. and 4:00 p.m.

Why we clean sewer mains

Sewer main cleaning helps prevent blockages and backups by removing build-up in the mains including tree roots, grease, grit and sand. This important maintenance work keeps our sewer mains flowing, reduces the potential for nuisance odours, and helps protect our infrastructure.

Sewer main cleaning is also done for CCTV inspection work.  These inspections allow us to see the condition of our sewer mains and make necessary repairs or replacements.

We apologize for any inconvenience during this important maintenance work. Your patience is greatly appreciated.

What to expect

  • toilets, sinks and other appliances can still be used during cleaning.
  • Air pressure in the sewer can create noise in sewer pipes, and may cause water to splash out through toilets, sinks and drains. Keeping toilet lids closed, and sink drains plugged when not in use will help avoid spills.
  • Sewer cleaning can create short-term nuisance odors. Odors can be cleared by opening a window for a few minutes, and running water down sink and bathtub drains, flushing toilets, and pouring a pail of water into basement floor drains.
  • No chemicals are used in sewer main cleaning. High pressure water is used to loosen debris and flush pipes. A high-powered vacuum then removes debris from the pipe, and the waste is deposited within the vacuum truck.  It is then transported to a sewage facility for disposal.
