Water-Energy-Pollutant Nexus Assessment of Water Reuse Strategies in Urban Water Systems using Metabolism Based Approach
This study analyses the water-energy-pollutant nexus performance of urban water reuse strategies by using urban water metabolism for a long-term planning period. A nexus assessment framework is developed for an Urban Water System (UWS) based on the WaterMet2 tool to track down water, energy and eutrophication flows over the main components of the UWS. A set of key performance indicators is then selected to represent the water-energy-pollutants nexus. The suggested method is demonstrated in a real case study in Mexico for eight hypothetical reuse strategies including six greywater (GW) recycling options (decentralised) and two reclaimed water distribution (centralised) that are compared with Business As Usual (BAU) strategy ('do nothing') in the UWS. The intervention options are set up at either 10% or 50% of adoption rates (proportional to household and demands within the UWS) to be implemented at years 10 and 20. The results show that greywater strategies consume more energy than the BAU if aerated technologies are implemented but the same strategies can reduce eutrophication due to reduction of untreated discharge of pollutions into receiving water bodies and potable water saving. Combining low-energy GW options with high adoption rates results in highly efficient performance with respect to nexus approach. The proposed metabolic-nexus based approach is able to provide useful information about the performance and environmental impacts of centralised and decentralised water reuse options to support management decisions.
