METRO VANCOUVER is constructing a new water main in the City of
Coquitlam to optimize the capacity of the existing Coquitlam water
supply system and to meet the growing demand for drinking water
in the region with the eventual expansion of the source supply under
the Coquitlam Lake Water Supply Project. The Coquitlam Water Main
is approximately 12 kilometres long, and ranges in diameter from 2.2
to 3.2 metres. The water main is being constructed in four sections.
Construction of the first pre-build section is underway. •
