The smart reuse of "greywater" from showers, wash basins and laundry for non-drinking uses such astoilet-flushing and irrigation in the garden has been shown to reduce water bills by up to 40%.Consequently, there is much interest in this technology, especially in highly-populated urban areas.Singapore is one such area. Bio Nano Consulting has recently developed a software program called WReNwhich helps urban designers calculate the cost/benefit ratio of proposed greywater recycling systems –this is the first such software program that provides this level of detailed analysis. In this project we willmeet with experts in Singapore to understand the specific issues with water reuse there and will find asuitable industrial park or housing complex which will act as a testbed for a follow-up study todemonstrate the WReN system in a real-world setting with actual data. This will help speed thedevelopment of new water reuse systems in Singapore and help that country save one of its precious andlimited resources.
