Notice Title
Trunk Mains AMP8 Roll Out: Distributed Acoustic Sensing (DAS) Fibre Sensing Solution
Notice Description
Thames Water is seeking to significantly improve its ability to detect leakage and bursts across its trunk mains network, where current monitoring coverage remains limited. This lack of visibility restricts early detection and response, increasing the risk of water loss, asset failure, and service disruption. To address this, Thames Water intends to roll out a Distributed Acoustic Sensing (DAS) fibre sensing solution, with the ambition of achieving near-100% coverage across its trunk mains estate. DAS technology offers the potential to transform network monitoring by converting fibre optic cables into thousands of acoustic sensors, enabling continuous, real-time detection of leaks, bursts, and third-party interference over long distances. The solution must be scalable, cost-effective, and capable of integrating with Thames Water's existing systems and operational workflows. Thames Water is interested in identifying potential service providers who can propose solutions that directly address this challenge. Providers will need to demonstrate how their approach will deliver reliable coverage, actionable insights, and long-term value. Key considerations include deployment strategy, data quality, system integration, and support for future enhancements in predictive maintenance and leakage reduction. The successful partner(s) will play a critical role in helping Thames Water achieve its strategic goal of near-total trunk main monitoring coverage through fibre sensing. Thames Water reserves the right to refine the award criteria. Please note that that deadline for asking for access to the PSQ & submitting of the PSQ is Monday, 2 March 2026, at 10 am.
Lot Information
Lot 1
Options: Thames Water reserves the right to: * Extend the contract beyond the initial 2 year term through one or more extension periods, up to a maximum contract end date of 30 June 2034. * Procure additional quantities of the DAS fibre sensing solution, associated hardware, software licences, analytics modules, and related support services where these are consistent with the scope and purpose of the original contract. * Implement further deployments across additional trunk main routes as operational priorities evolve, subject to the overall contract value and term limits.
Renewal: Thames Water envisages that the contract will be awarded for an initial term of 3 years with options to extend by 1 year or longer, up to a maximum overall term of 8 years.
