## Summary

Scottish Water plans to procure network leakage management services across its water network in Scotland. The work covers proactive and reactive leak detection and investigation, including Active Leakage Control, District Metered Area and trunk-main investigations, reported-leak verification, Unaccounted for Water identification, and targeted strategies for Priority and Deficit Zones. Suppliers may also provide network monitoring, flow, pressure and telemetry analysis, leakage forecasting, find-and-fix services, excavation, repair, reinstatement and traffic management. The scope includes customer-side leakage investigation and engagement, emergency and seasonal response, performance reporting and continuous improvement. Complementary flushing, network conditioning, commissioning support and network assessments may be included. Capital maintenance and capital delivery activities are excluded. The service category is leak-testing and related water-network services.

This procurement is at the planning stage: Scottish Water has stated an intention to procure, but has not issued an invitation to tender. The envisaged contract duration is 8–12 years, likely comprising a five-year initial term with extension provisions. The estimated total value is £400 million, with expected annual spend of approximately £50 million; the final scope may change after market engagement. Scottish Water expects an outcome-based model, linking supplier incentives to leakage reduction, leak-run-time reduction, repair quality, customer impact and operational efficiency rather than activity volumes alone. Market engagement events are intended during October 2026, with 8 October 2026 anticipated for the market day. Interested organisations are asked to register by 12:00 on 25 September 2026. A subsequent notice is anticipated on 18 January 2027.

The planned service should suit water-sector contractors, leakage specialists, network analytics providers, repair and reinstatement firms, customer-side leakage specialists, and suppliers offering integrated end-to-end delivery. Scottish Water is seeking organisations able to provide all or part of the requirement, including specialist services, digital leakage solutions and emerging technologies. Relevant strengths include Active Leakage Control, network monitoring, telemetry and data analysis, leakage forecasting, DMA and trunk-main investigation, excavation, repair, traffic management, emergency response, flushing and network conditioning. Suppliers should be ready to demonstrate previous water-sector experience, geographic coverage, a base or operational capacity in Scotland, innovative approaches and the ability to work collaboratively with operational, planning and analytical teams. The buyer is also interested in delivery models that improve leakage performance beyond a traditional client-contractor relationship and welcomes SME participation.

## Notice

1. Network Leakage Management Services To provide proactive and reactive leakage detection services to identify, prioritise and investigate leakage across the network, including Active Leakage Control (ALC), DMA investigations, trunk main investigations, verification of reported leaks, identification of Unaccounted for Water and targeted strategies for Priority and Deficit Zones. The model will be outcome-based, with suppliers incentivised against leakage reduction, leak run-time reduction, repair quality, customer impact and operational efficiency measures, rather than solely activity-based measures such as leaks found or repairs completed. The scope may also include complementary network optimisation, flushing and conditioning activities that support network performance, resilience and water quality outcomes.
