This report articulates the reasons for, and the pathways by which, utilities can achieve a water-energy conservation synergy. Based on research and interviews with utility staff and experts, the report presents the procedural steps for implementing joint efficiency programmes. For different types of collaborative programmes such as rebates or audits case studies are provided. The study revealed that once initial logistics are worked out, it is easy to implement joint programmes. It also points out challenges, such differences in the operations of water, electricity, and gas utilities, as well as the lack of interest or ability by utilities to implement efficiency programmes.
