Operations & Assets Operations & Assets
cannot be understated. It's a fantastic
example of the capital investment
programme delivering real long-term
benefits for communities to reduce
flooding, help deal with the impact
of climate change and improve the
environment."
Much of the area's underground
infrastructure for water and wastewa-
ter dates to the Victorian era when it
led the way in introducing improve-
ments to deliver positive impact on the
health of our communities.
The tunnel is the flagship project
in Scottish Water's investment in Glas-
gow's wastewater infrastructure.
If you have an asset or project you

Douglas Millican, Scottish Water's chief executive, says:
"We are delighted to have completed the Shieldhall
Tunnel, which is the flagship project in Scottish Water's
investment in the wastewater infrastructure in the
Greater Glasgow area – the biggest in well over a
century.
"The city's wastewater infrastructure required major
improvements to help transform it into a modern, inte-
grated and sustainable system which will improve the
environment and biodiversity on the River Clyde and help
tackle flooding.
"As the Greater Glasgow area continues to develop,
we are modernising our wastewater infrastructure to
support the needs of both existing and future
customers.
"The completion of the Shieldhall Tunnel is a key part of
that network modernisation."
