Thames seeks early market engagement for SESRO

Thames Water has published a Periodic Indicative Notice (PIN) to initiate early market engagement for its proposed SESRO super reservoir in Oxfordshire.

The company is updating contractors and investors on the development of the reservoir, including on the commercial and procurement strategies for two large-scale future opportunities:  

• Infrastructure Provider (IP): the IP will be responsible for designing, building and financing the majority of assets within the SESRO project.

• Main Works Contractor: to construct and commission the assets under a target price contract, working initially with Thames and then with the IP once that contract is awarded. 

Thames said the engagement is also an opportunity for contractors and investors to inform and shape its approach. 

Interested organisations are invited to complete the registration-of-interest form and join the SESRO market engagement event taking place on 17 March 2025.
