    "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.\nDAS 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\u0027s existing systems and operational workflows.\nThames 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.\nThames Water reserves the right to refine the award criteria. Please note that that deadline for asking for access to the PSQ \u0026 submitting of the PSQ is Monday, 2 March 2026, at 10 am.",
