PUBLIC WORKS DEPARTMENT
The Public Works Department is responsible for the operation and maintenance of the City’s
water, sanitary sewer, storm drainage, road and dyke infrastructure, as well as the operation
and maintenance of the Wastewater Treatment Plant (WWTP).
PUBLIC WORKS
Public Works liaises with local developers and contractors
to ensure new infrastructure is built to acceptable
standards, prior to the City taking it over. The department
also strives to ensure there is minimal delay in connecting
newly constructed infrastructure to existing, to allow new
development to be completed as timely as possible.
The Public Works section maintains:
•
565 km of paved roadways
•
38 km of unpaved roads
•
305 km of storm drainage systems
•
50 km of dykes
•
Approx. 1000 km of open drainage ditches
•
300 km of sanitary sewer
•
455 km of water distribution mains
•
8 drinking water production wells
•
13 water storage reservoirs
•
3 storm water drainage pump systems
UTILITIES
The Utilities Electrical/Mechanical and Underground sections
operate and maintain:
•
47 sanitary pump stations
•
8 drinking water production wells
•
13 water booster pump stations and 13 reservoirs
•
700 + kilometres of water and sewer pipe systems
Both utility sections are responsible for operating the water
system in accordance with the City’s Drinking Water Quality
Assurance Program initiatives and the Provincial Drinking
Water Protection Act.
Wastewater Treatment Plant
The WWTP processes and treats over 6.5 million litres of the
City’s wastewater per year. The plant is continually upgraded
to cope with increased volumes as the City’s population
increases.
The Cross Connection Control (“CCC”) program is
administered by Public Works. The CCC program minimizes
risk to the City’s drinking water from cross contamination.
The department’s goal in this area is to ensure that a supply
of safe, high quality drinking water is available at all times.
FLEET MAINTENANCE
The Fleet Maintenance section is responsible for maintaining
the City’s vehicle and equipment fleet, which currently
numbers 205 units, ranging from grass mowers to dump
trucks to excavators and graders. This section also
maintains the Chilliwack Fire Department’s fleet of
vehicles and fire-fighting apparatus.
2011 Highlights
McGillivray Drainage Pump Station Flow Control Gate
A custom fabricated steel flap gate was placed on the outlet side of the McGillivray
flood box. The flap is intended to help free flow through the flood box during low
water conditions. It also allows the
safe passage of migrating fish from McGillivray Creek Into the Vedder Canal and
vice versa.
The new flap gate uses water pressure created by high water on the Vedder River
side of the gate, to seat and close the gate, blocking water passage to the “dry
side” of the dyking system.
