Description
Summary:Worldwide, there has been an increasing trend for water supply managers to look towards the use of water demand management (WDM) initiatives as an alternative to other more traditional approaches for ensuring that water supply can meet demand. Despite increasing recognition of the wide range of benefits possible through these WDM initiatives, there are few published works that are readily accessible to decision makers laying out concepts and methods through which a valuation of WDM initiatives can be made. To address the issue, this paper describes a comprehensive framework to evaluate WDM and alternative initiatives. It describes the results of applying the framework ex‐post to the assessment of WDM initiatives put in place by Tauranga City Council in New Zealand. This case study is one of the leading examples of the implementation of WDM in New Zealand, and provides a strong value case for investigating other possible applications of WDM.
