Caledonia Water Alliance Secures Water and Wastewater Infrastructure Contracts with Scottish Water

Caledonia Water Alliance (CWA), a Morrison Utility Services (MUS) and AECOM joint venture, has secured a six-year extension (2021–2027) to its water infrastructure contract with Scottish Water. In addition, Scottish Water has appointed CWA to expand its scope of services to include the delivery of all wastewater infrastructure work for Scotland for the same period.

Following confirmation of the new agreements, from 2021-2027 CWA will deliver an estimated £600m of water and wastewater infrastructure works in Scotland on behalf of Scottish Water.

Peter Carolan, Executive Director, Morrison Utility Services and CWA JV Board member, comments: “We are delighted to have secured these agreements with Scottish Water. Since 2015 we have delivered over £380 million of water network interventions including capital maintenance, water quality, network enhancements and improvements in overall resilience of Scottish Water’s water supply network all aimed at achieving world class customer service for our client.”

David Sanderson, Scottish Water Account Director, Morrison Utility Services, comments: “This reappointment and expansion of our scope reflects CWA’s excellent work and collaboration with Scottish Water over the past six years. This provides an excellent platform to drive further innovation and efficiency.”

Chris Gray, AECOM Head of Water for Europe and CWA JV Board member said: “This is a fantastic opportunity for AECOM and Morrison Utility Services to further improve our integration over the next six years, developing our water and wastewater teams in Scotland, driving efficiency, innovation and Net Zero Carbon with Scottish Water, whilst creating jobs for local apprentices and engineers – leaving a lasting legacy for Scotland.”

CWA was first appointed to support the delivery of the water infrastructure element of Scottish Water’s future Quality & Standards IV (Q&S IV) Capital Investment Programme for the regulatory period for the regulatory period 2015 to 2021.

Since 2015, the scope of work delivered on behalf of Scottish Water has included programme management and the design and delivery of essential water network infrastructure works across the whole of Scotland including new assets, renewals, modifications, maintenance and refurbishment of water networks and pumping stations.

Moving forward into SR21 CWA will also deliver wastewater infrastructure works including sewer flooding, sewer networks/overflows, pipe bridges and wastewater pumping stations.
