From Pee to Potable: Steering from Day Zero through Urban Wastewater Recycling
Abstract: With urban populations burgeoning, water demand growing in the agricultural, energy and industrial sectors, and climate change intensifying droughts, water-scarce cities are challenged with maintaining a water secure future. Through a self-developed Water Security Index (WSI), this paper evaluated the role of wastewater reuse in defining city water portfolios. The index was then applied ... read moreto four water scarce cities to evaluate the different components of a resilient water system and the potential of wastewater reuse in boosting water security. Data gathered showed that wastewater reuse contributed small percentages to water portfolios. The index suggested that wastewater reuse (toilet to tap) has potential to increase a city's potable supplies and that cities with diversified water portfolios scored higher in the WSI. Thus, this paper concluded that the adoption of wastewater recycling and reuse is essential in adding to diversity of water sources to build a resilient water system.
