Glan Agua Farrans JV (GAF JV - a joint venture between Glan Agua and Farrans) have completed works under the Process and Network Modifications Framework for Affinity Water at two existing treatment sites – Amersham in Buckinghamshire and Northmoor in Hertfordshire – in a multi-million-pound contract.

GAF JV was awarded two projects in Lot 2 of the framework to provide crucial upgrades to Affinity Water's existing treatment infrastructure. The works involved the construction of a sophisticated turbidity treatment process plant to supplement the existing treatment plant within the confines of the Amersham 9 ML/D works and Northmoor 18 ML/D works in tight site footprints.

The projects were constructed under the requirements of the client regarding the environmental, ecological, safety and stakeholder constraints and both plants were brought into service in recent months.


Neil Barnes, Farrans' regional director for civils in England, said: "Both Glan Agua and Farrans came to this project with the right mix of capabilities in the water market to deliver to a high standard on a complex project. We have worked closely and collaboratively with Affinity Water to achieve an excellent result at each location. Off-site construction was at the forefront of the design, utilising modular and containerised units to deliver the challenging programme within a tight site footprint. The modern method involved all modules being manufactured off-site, with all equipment suppliers delivering to our supply chain partner's DfMA facility, where they were assembled. The modules were then delivered to the site, placed and installed immediately in a 'plug and play' fashion. This methodology reduced the level of on-site resource and helped reduce any safety risks."

Paul Gardner, managing director of Glan Agua UK, said: "We approached this project with a new level of design innovation and utilised a Common Data Environment (BIM 360) to enable input from the multiple international supply chain partners and stakeholders. This ensured an efficient and accurate process. Furthermore, the plants were designed to be decommissioned and potentially re-used elsewhere so they are at the forefront of industry sustainability. We are pleased that we have been able to complete these extensive works successfully and on time in the face of the challenges presented by the pandemic by adapting quickly and utilising the agility of both JV partners."

Glan Agua Farrans JV continues to work together on other key frameworks including the IF105 Framework with NI Water.
