Two lots are available. Targeted Catchment Investigation Services will investigate defined catchment areas to identify and reduce sewer blockages, pollution incidents, flooding and customer disruption. Work can include sewer and manhole inspections, cleaning, CCTV surveys, root-cause analysis, first-time fixes and recommendations for follow-on work. CCTV & Cleaning covers planned and reactive sewer cleaning, CCTV investigations, flow management, waste disposal, defect coding, emergency response and pollution escalations. Suppliers must provide the labour, vehicles, plant, equipment, permits, licences, traffic management and records needed for delivery on public highways, private land and other locations. The process has reached tender: Thames Water has invited offers through a selective competitive flexible procedure for a closed, multi-supplier framework, with bids permitted for one or both lots. The first stage is a Pre-Qualification Questionnaire, followed by an Invitation to Negotiate for selected suppliers and potentially a Best and Final Offer. Questions must be submitted by 21 September 2026 at 17:00, and expressions of interest and PSQ access requests by 28 September 2026 at 12:00. The framework is intended to run from 1 February 2027 to 31 January 2030, with extensions potentially taking the maximum term to 31 January 2035. The published value is £0.

Lot 2 suits providers able to deliver specialist cleaning, CCTV enabling, flow management, waste disposal, defect identification and coding, emergency response and pollution-related work. Suppliers need sufficient labour, vehicles, plant and equipment, together with the ability to secure permits, manage traffic and work across highways, private land and varied operational locations. Selection will consider relevant experience, technical capability, operational capacity, health and safety, quality management, environmental performance and the ability to meet the service requirements. ## Notice Lot 1 - Targeted Catchment Investigations (TCI) This lot covers the delivery of Targeted Catchment Investigations (TCIs) across Thames Water's wastewater network to identify and reduce the risk of sewer blockages, pollution incidents, sewer flooding and customer service disruption.
