Valued at £50 million, the project involved creating a turbidity treatment process within limited site footprints. Utilising submerged ultrafiltration, the solution was designed with modular Design for Manufacture and Assembly (DfMA) and Building Information Modeling (BIM) to streamline construction and reduce time and quality risks. The project featured the innovative first application of submerged ultrafiltration and a collaborative approach using a Common Data Environment (CDE).

The sustainable design allowed for decommissioning and reuse of the plants, and special attention was given to minimise impact on a nearby care home.

The projects met strict HS2 Environmental Minimum Requirements and were delivered on tight schedules through collaborative planning.
