Thames Water Unveils Major Reservoir Plans to Benefit 15 Million People

Thames Water is making waves with its recent Periodic Indicative Notice (PIN), signaling a significant step forward in its ambitious plans for a new reservoir in Oxfordshire. This isn’t just a drop in the bucket; the proposed reservoir is poised to hold up to 150 million cubic meters of water, covering an impressive surface area of about 7 square kilometers. This venture is not merely a local initiative; it’s designed to serve a staggering 15 million people across the region, making it a linchpin in the water supply strategy for years to come.

The UK government has already recognized the importance of this project, designating it as a Nationally Significant Infrastructure Project. This designation comes on the heels of the government’s approval of Thames Water’s Water Resource Management Plan 2024, which underlines the pressing need for this reservoir amid growing climate challenges and an ever-increasing population. With operational plans set for 2040, this reservoir will be crucial in ensuring a reliable water supply during drought conditions, supporting not just Thames Water but also Southern Water and Affinity Water.

What’s particularly noteworthy about this initiative is Thames Water’s proactive approach to market engagement. The company is keen to foster relationships with contractors and investors early on, providing them with insights into the commercial and procurement strategies that will underpin the project. Two key roles have been identified: the Infrastructure Provider (IP) and the Main Works Contractor (MWC). The IP will take the reins on design, construction, and financing, while the MWC will focus on the actual building and commissioning of the assets. This structured approach not only clarifies responsibilities but also allows for a collaborative environment where market trends and contractor capabilities can be aligned with the project’s goals.

Mohit Farmah, Head of Procurement and Supply Chain at Thames Water, expressed enthusiasm about this engagement process. “We are excited to kick-start the year by getting the next stage of market engagement for our proposed reservoir underway. Contractors and investors have a crucial role to play in informing our approach and helping drive this vital project forward. We have been encouraged by the level of interest the market has shown to date. I encourage all interested parties to register their interest to engage with us and shape the future of this vital project, including our spring market engagement event on Monday 17 March.”

The invitation for participation is clear. Interested organizations are urged to register their interest through a dedicated form, with the spring market engagement event scheduled for March 17, 2025. This early engagement not only opens the door for potential suppliers and investors but also sets the stage for a more resilient water infrastructure that can adapt to the challenges posed by climate change and population growth.

As the water sector grapples with unprecedented demands and environmental pressures, Thames Water’s initiative could serve as a template for future projects. By prioritizing collaboration and transparency, the company is not just building a reservoir; it’s laying the groundwork for a more sustainable and secure water supply for generations to come. The ripple effects of this project could very well redefine how water utilities approach infrastructure development in an era where every drop counts.
