Sewer Operations: Maintaining the System
The City's storm and sanitary sewers need on-going inspection
and maintenance to ensure that they work properly, and continue to protect the
health and property of the public. City staff assess and respond to
problems through long-term monitoring, computer modeling, video and sonar
inspection, and information provided by the public.
Private Drain Connection Relining
In April 2010 Sewer Operations began lining private drain connections (PDCs)
where possible instead of excavating the sewer line. So now instead of this:
You might see this:
What a difference that makes on a street! No ripped up road,
sidewalks, lawns. No closed roads. The crew completes its work in half a day
versus the 1-3 days that it would take to dig the PDC up. Although not all PDCs can be
lined a large percentage can. Since implementing the PDC lining program the City
has been able to reduce the average cost of a PDC replacement by 20%. This
savings is passed along to the property owner and to the citizens of London.
