Abstract

It is important for us to be able to measure progress towards decentralisation. This is particularly so for land or real estate developments. A rating tool has been developed for determining the water use performance efficiency of land developments. The rating score also measures how well the land development is towards implementing decentralised water system. Land developments can draw supply from scheme water and dispose of wastewater through a centralised sewerage system, or they can rely on rainwater harvesting and reuse water entirely within the land development, or anywhere in between from a centralised to a decentralised system. The rating tool quantifies the volumes of water drawn from all sources and wastewater disposed or reused through all routes, compares these with best practice water use volumes and arrives at a score out of 10 (equivalent to best practice) for the land development. The algorithm for the rating tool is implemented using Excel workbook/worksheets prompting users to enter required input values. Application to four case study land developments is presented. The rating tool will assist land developers in improving the water use efficiency of the development, in promoting their water efficient real estates to consumers, and for consumers in choosing alternative real estates, and for regulators in facilitating more efficient use of water for land development.
