    Water Demand Management: An economic framework to value with case study application (PDF 700KB)

    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 (WA7090/4), and the development and of a framework (WA7090/5). This was applied to a case study (WA7090/6) 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.

    Barriers to Water Demand Management: Health, Infrastructure and Maintenance (PDF 2MB)

    David Kettle

    This report documents the research findings from a literature review focussed on aspects related to rainwater tanks and greywater systems as part of the water supply demand management 'tool box'.  It discusses health risks, maintenance/ownership, centralised/decentralised, barriers to adoption and possible solutions.

    A Framework for Valuing Water Demand Management: Tauranga City Council Case Study (PDF 838KB)

    Nicola Smith, Garry McDonald

    This conceptual framework is the second part of a project which addressed the question, 'why' (would an organisation adopt WDM). To do this Beacon commissioned work from Market Economics in three parts: a literature review (WA7090/4), the creation of a comprehensive conceptual framework (WA7090/5) and a case study to test the framework utilising data from Tauranga City Council. Based on the application of the economic framework developed in the first two reports , it is estimated that as a result of 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.

    A Framework for Valuing Water Demand Management: Conceptual Framework (PDF 836KB)

    Nicola Smith, Garry McDonald

    This conceptual framework is the second part of a project which addressed the question, 'why' (would an organisation adopt WDM).  It was clear that a rigorous economic analysis of the value of water demand management was needed to help councils and water authorities to demonstrate the value of such an approach to decision-makers and communities. To do this Beacon commissioned work from Market Economics in three parts: a literature review (WA7090/4), the creation of a comprehensive conceptual framework and a case study to test the framework utilising data from Tauranga City Council (WA7090/6).

    Integrated Water Management Design Criteria Report (PDF 354KB)

    David Kettle

    This project developed a product design criteria methodology to assess water saving products and systems to identify potential commercial opportunities.  The best overall 'score' came from a combined 'system', comprising a low flow shower head, a water efficient washing machine, a 9,000 litre rain water tank and greywater reuse.Two potential commercial opportunities were identified; the installation of a relatively small 200 litre rainwater tank attached to the side of the house to supply toilet water only; and a 'modular' tank system where small storage blocks of 200 to 300 litres each could be connected up in irregular shapes to fit under decks, etc.

    Energy-Water Relationships in Reticulated Water Infrastructure Systems (PDF 342KB)

    Ben Kneppers, Damon Birchfield, Maggie Lawton

    The report provides an initial analysis of the relationship between energy use and reticulated water supply and wastewater treatment.  A literature study was supplemented by energy and water use data from four distinct reticulated water systems (Waitakere, Palmerston North, Kapiti and Nelson).  The data was considered for energy use and energy efficiency, and how improvements could be made.

    Slowing the Flow: A Comprehensive Demand Management Framework for Reticulated Water Supply (PDF 1.4MB)

    Maggie Lawton, Damon Birchfield, Dorothy Wilson

    Based on research, this publication provides a comprehensive demand management framework for all working with reticulated water supply. Slowing the Flow recognises the complex issues in meeting increasing demand, controlling costs (hence pressure on rates), conserving a scarce resource and adopting fresh thinking while maximising the benefits of new technologies.

    Best Practice Water Efficiency Policy and Regulation (PDF 1.4MB)

    Maggie Lawton, Damon Birchfield, David Kettle and Chloe Trenouth

    This report is an in-depth investigation into demand management practices in New Zealand and overseas and the regulation and other policy approaches that impact on the degree of success of their uptake. Shows that water conservation technologies are readily available but our water conservation policy and regulations are lagging behind and need further development to better support the adoption of such technologies.

    Water Efficiencies: Report on Existing Technologies/Expertise in New Zealand (PDF 116KB)

    Sarah Heine

    This report identifies three key areas for water efficiency: front loading washing machines, water efficient toilets, and reduced garden water consumption. It suggests that, rather than investigate new technologies, the consumer needs to be encouraged to make use of existing technologies and information via education and promotion.
