Water demand management: An economic framework to value with case study application

Nicola Smith, Garry McDonald, Dorothy Wilson.

This report synthesises three reports produced as a result of the development of a framework to value water demand management and its application to Tauranga City Council. It describes a brief literature review, and the development and of a framework. This was applied to a case study to demonstrate the potential value of water agencies adopting and implementing water efficiency measures. The case study result shows that in implementing a water demand management approach, Tauranga City Council has delayed the implementation of the next major water supply infrastructure identified for the city’s water supply, by approximately 10 years with a net benefit to the community of $53.3 million in 2009 terms.
