Scottish Water is about to start work on the third phase of its Glasgow Resilience Project – the scheme will improve its water mains network in the south west of Glasgow by installing more than seven miles of new pipes.
The Glasgow Resilience Project will connect the Glasgow area’s network and the system in Ayrshire to increase resilience and protect supplies for customers and will involve the use of innovative construction materials and techniques to reduce carbon emissions and power requirements.
Around a million customers will benefit from the two networks being connected.
The new water main will be installed in the Ibrox, Mosspark, Pollok, Priesthill, Nitshill, and Parkhouse areas of Glasgow.
Connecting the networks will provide a two-way water supply between the Milngavie Water Treatment Works (WTW) system, which provides water for more than 700,000 people across much of the Glasgow area, and the Bradan WTW system which supplies more than 200,000 customers across much of Ayrshire. It will also benefit almost 50,000 customers in East Renfrewshire.
The new main will run from Ibrox to a reservoir storage tank in the Parkhouse/Darnley area.
A new pumping station will be built at Ibrox which will push water to an existing pumping station in Parkhouse/Darnley for onward distribution to Ayrshire.
Four tunnels - one under the M8 motorway and the Glasgow-Ayr railway line, another under the Paisley Canal railway and White Cart Water, another under the Glasgow-Barrhead-Kilmarnock railway, and one under the Levern Water - will be constructed along the route of the new main.
In the event of a disruption to water supply in either Ayrshire or Glasgow, the new system will allow millions of litres of water to be transferred in either direction, minimising the impact on customers if there is a burst main or other operational issues.
Mark Dickson, Scottish Water’s Director of Capital Investment, said:
“Linking our supply systems will ensure that high quality drinking water can continue to be supplied to current customers and for generations to come.
“The investment in new pipelines and associated infrastructure below ground will also support the continued development above ground in communities across these areas and will enable them to continue to grow and thrive.”
Innovations include carbon reducing construction materials
The design of the new network incorporates carbon reducing construction materials and methods including innovative self-restraining pipe. Solar panels will also offset the power demands at the new Ibrox pumping station, with the new mains using gravity to reduce power use by 60 per cent.
The project will be delivered by the water company’s alliance partner Caledonia Water Alliance (CWA) and is expected to be completed by 2023. It is the third stage of the overall multi-million pound scheme which has already delivered improvements in Ayrshire.
UK water companies are invited to join an upcoming webinar which will explore how the sector can take indirect potable reuse (IPR) from concept to full-scale operational reality.
James Sumsion, CEO of predictive water intelligence specialists Kohtari, says the water sector needs to take a giant leap forward, so that it can anticipate and act upon water quality issues - rather than merely react.
Ray Moulds, Sales Director at Flood Control International, takes a look at how automated sliding floodgates are supporting secondary containment at water and sewerage company sites.
With the UK government demanding a 50% reduction in storm overflow spills by 2029, the era of reactive management is over. Speaking in the House of Commons on 21 July 2025, then environment secretary Steve Reed said, “This Government will cut water companies’ sewage pollution in half by the end of the decade.”
