February 15, 2017 - 11:00 a.m. - The Lake Huron Primary Water Supply System is undertaking
a critical repair of the transmission pipeline in the Denfield area. The transmission
pipeline repair operation began at 1:00 a.m. on Wednesday February 15th when the
water treatment plant was shut down, and crews started to close the mainline valves
and drain the isolated pipeline. By 10:00 am, crews had completed excavating the
pipeline and started the process to cut out and remove the damaged pipe.
The removal and replacement of the damaged pipe is anticipated to take as much as
20 hours to complete before the pipeline can be refilled and pressure tested. It
will take up to another 24 hours to refill area reservoirs and return the water
supply system to normal operations; anticipated to be complete by Friday morning.
Municipalities supplied by the Lake Huron Primary Water Supply System include Bluewater,
South Huron, Lambton Shores, Lucan Biddulph, North Middlesex, Middlesex Centre,
Strathroy Caradoc and the City of London.
"The work appears to be going well and on schedule so far" says Andrew Henry, Division
Manager for the regional water systems. "We will need to carefully watch the reservoir
levels throughout the region to ensure there aren't excessive demands on the system
during the repair operation" says Henry.
The supply of treated drinking water to the City of London from the Elgin Area Primary
Water Supply System has been increased, however the majority of the water supplied
to the consumers by the Lake Huron Primary Water Supply System will be provided
from storage reservoirs throughout the region while the pipe repairs are being undertaken.
The quality of the water supplied to area municipalities and consumers is not affected,
however some communities in the region may experience lower than normal water pressures.
Consumers are encouraged to contact their local municipality if they experience
discoloured water or have no water.
