Sewer flushing program

Routine maintenance keeps Guelph’s sewer pipes flowing

Cleaning is done year-round, Monday to Friday between 7 a.m. and 5 p.m., and usually takes a few hours on each street. 

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.
