This report, submitted by a team from the University of Michigan Water Center and Safe Water Engineering, was provided to the Michigan Clean Water Public Advocate as an evaluation of a pilot program to fix residential water leaks free of charge in two Michigan communities. The evaluation was intended to learn from the pilot process from all perspectives—residents, plumbers, community-based organizations doing outreach, local media partners, state agency partners, and local governments and organizations. The evaluation includes an analysis of the impact of premise plumbing repair on water loss reduction and corresponding energy savings. Outputs of the evaluation include the identification of lessons learned and best practices, additional observations from the evaluation team, and recommendations for future programs.
