Community of Practice: Energy Efficiency & Decarbonisation

Supporting water and wastewater utilities to advance their short and long-term energy goals.

Overview

Water and energy are deeply interconnected across the entire utility value chain. Decisions around asset management, leakage reduction, pumping strategies, and treatment process optimisation all have direct impacts on energy use and carbon emissions. As utilities face rising energy costs and increasing pressure to decarbonise, this Community of Practice brings together utilities, technology providers, consultants, researchers, and industry experts to share practical experiences, explore digital solutions, and co-create resources that support utilities at every stage of their energy and decarbonisation journey.

Objectives

  • Support utilities in reducing operational energy use and emissions through practical, scalable strategies.
  • Bridge day-to-day energy efficiency initiatives with broader decarbonisation and resilience goals.
  • Foster peer-to-peer learning by sharing real-world utility experiences, challenges, and best practices.
  • Co-create practical community resources, including assessment tools, benchmarking activities, white papers, and use-case libraries.

Structure

The Group hosts quarterly regional and cross-region community calls organised around three connected learning streams:

1. Measure & Understand: Building confidence in energy and emissions data through baselining, carbon accounting, monitoring, and benchmarking.

2. Optimise & Operate: Turning insights into operational improvements across pumping, treatment processes, automation, AI, and water loss management.

3. Transform & Decarbonise: Supporting long-term system change through net-zero roadmaps, energy recovery, electrification, governance, and organisational resilience.
