SCOTTISH Water has confirmed the preferred bidders to deliver a multi-billion pound transformation of water and waste infrastructure.

Firms were invited to bid to be involved in an enterprise-style approach to enhancing Scotland’s water and waste water infrastructure over the period 2027 to 2033, with a potential extension for another six years.

Following the largest procurement ever undertaken by Scottish Water, the publicly-owned utility has announced that the preferred bidders are:

Stantec, primary designer
Aecom, primary designer 
M Group Water, asset delivery partner 
Mott MacDonald Bentley, asset delivery partner 
Farrans Limited, asset delivery partner 
WGM Engineering, asset delivery partner 
Ross-Shire Engineering, asset delivery partner 

Director of capital investment at Scottish Water, Rob Mustard, said, The enterprise is the most significant programme of investment and way of working we have ever implemented. It supports our goals of financial sustainability, customer and service excellence, and going beyond net zero, all while contributing to a flourishing Scotland.

Primary designers will be accountable for design across the enterprise, ensuring that our designs deliver our outcomes, and asset delivery partners will drive programme and project delivery, ensuring successful execution of capital works in line with those outcomes.

Once the legalities are completed, we see these organisations working with Scottish Water to form our enterprise, delivering a third of SR27 investments for our customers.

The procurement process started on November 25, 2024, and is expected to be fully completed by March 2026, Scottish Water said.
