Integrated Urban Water Management

Integrated Urban Water Management (IUWM) in land developments is becoming increasingly necessary in order to more efficiently utilise and manage water resources. Techniques including the control of stormwater runoff, increasing infiltration and providing opportunities for retention, treatment and reuse of both stormwater and wastewater, are well suited to being designed into the development rather than considered post-construction or not at all. There can be extensive capital investment by developers to implement IUWM which is often not returned in the land sales. This produces a disincentive for the developer unless the contribution is recognised and rewarded either financially or with appropriate marketing advantage. A system to rate land developments based upon IUWM has been developed that would quantifiably assess how effectively water resources would be utilised in a proposed land development. This assessment would provide a point of comparison between developments allowing property purchasers, developers, utilities and legislators to quickly compare how well the development performs in terms of IUWM, providing a mechanism for financial reward or recognition. This paper discusses the development of a model to quantifiably assess land developments for water efficient use and introduces a rating system with which land developments can be compared in terms of IUWM.

Abstract This paper describes the outcomes of an evaluation of Australia's Water Efficiency Labelling and Standards (WELS) scheme. WELS is a national, government-run scheme that mandates water efficiency labelling for indoor water-using fixtures and appliances. The scheme also imposes a minimum standard for some products. The evaluation considered the environmental and economic impacts of improvements in the water efficiency of WELS-labelled products since the scheme's inception in 2006 and forecast for 20 years. The study estimated water, energy, greenhouse gas (GHG) and utility bill savings as well as the costs associated with the scheme. The evaluation showed WELS to be an important component of urban water management in Australia, saving 112 GL in 2017–18, across the country, and 231 GL/year by 2036–37. The largest economic benefits of WELS came from the energy saving from reduced water heating. Over 30 years, these energy savings are also expected to reduce GHG emissions by a cumulative 53.5 Mt. On average, Australians saved $A42 (US$30) per person per year in 2017–18 due to the water efficiency driven by WELS. Overall, the evaluation shows the WELS scheme to be highly beneficial for Australia with significant net benefits to the present and projected into the future.

California, perhaps more than any other of the United States, has been a leader in water efficiency experiments. It adopted uniform efficient plumbing standards in 1978 for showerheads and faucets and the same for water closets in 1992. Comprehensive water management planning was adopted in 1983 for all water agencies serving more than 3,000 connections or 3,000 people, and in 1991, a Memorandum of Understanding was signed by major water utilities and environmental groups statewide - pledging to implement standardized water efficiency programs called “Best Management Practices” in an attempt to help save the dying Bay-Delta Estuary. The California Urban Water Conservation Council, created by this Memorandum, is a non-profit NGO formed to oversee the Best Management Practices and to enforce the terms of the Memorandum. Since the historic signing of this Memorandum ten years ago, the Council has become a national example of consensus partnership on water efficiency. Water utilities and environmental groups work together on defining programs for water conservation, not as adversaries fighting each other in the press or in the courtroom. Technical assistance provided by Council staff helps utilities plan and implement conservation projects. This paper will outline national programs and will focus specifically on the Council partnership, which has resulted in benefits to water utilities, environmental groups, and state governmental agencies alike.
