Southern Water Clean Water Network Optimisation

The Clean Water directorate of Southern Water faces mounting pressure to improve performance in relation to a number of operational measures, most notably leakage. Projects commissioned as part of the Clean Water Network Optimisation programme must deliver significant identifiable benefits in both the current year (22/23 – Year 3 of AMP7) that can be consolidated for the remainder of AMP7.

TIn the EP22 annual leakage target we expect to report reduction in leakage for 10 to 15 Ml/d from Year 2 Year 3. As Year 3 is the baseline year for AMP8 funding, it is critically important for Southern Water to meet this target.

Some groundwork for delivering these benefits has been completed through Phase 1 of the Advanced Pressure Management project, mains replacement schemes, enhanced find and fix effort, and three projects undertaken by our incumbent partners.

Southern Water seeks to identify the best partner to take forward the next tranches of Clean Water Network Optimisation projects to continue to deliver benefits.

The benefits of the next tranche of Clean Water Optimisation projects are expected to be found in a number of areas such as:

Consolidated View of Leakage Operations

Smart Meter Data Integration & Continuous Flow Alarms

Performance of Leak Detection pinpointing

Trunk Main Burst Mitigation and Prevention

Data Validation and Consolidation of Reporting within Live Dashboard Environment

The new partner will be expected to provide:

• Demonstrable history of working with water companies and applying established and innovative approaches to challenges in the industry
• Combined experience in operational roles in water companies and consultancy experience providing advisory and implementation services
• Breadth to devise and implement technological as well as process, organisational and cultural solutions
• Ability to mobilise – at pace – a team with the capacity to deliver the scale of change needed to achieve our targets for AMP7 Year 3 and beyond
• Value for money in the proposed commercial arrangements, including rate card.
