A partnership of Morrison Utility Services and Aecom, Caledonia will deliver around £360 million of water infrastructure investment over the six years.
BBV, a partnership of Black and Veatch and Byzak (part of Amey), will be Scottish Water’s waste water infrastructure alliance partner delivering around £340 million of investment.
An element of the alliances’ programme of work will be self-delivered and the remainder delivered through contract partners.
The alliances are now working with Scottish Water to procure tier one suppliers to help deliver the programme.
Geoff Aitkenhead, Scottish Water’s director of asset management, said: “We had a large number of interested parties keen to work with Scottish Water on our next investment programme. Following a diligent and extensive procurement process the Board of Scottish Water has selected two alliance partners.
“This is the first stage of ensuring we have the right partners, with the right skills, to help us deliver the next stage of our continuing investment which is delivering real benefits to our customers while supporting the economy and jobs in Scotland.”
