Regions that are undergoing water shortages serve as a highlight of the energy-water nexus, where pursuing new water sources can reveal new conflicts with energy resources. Reclaimed water in the form of municipal wastewater treatment plant effluent can serve an attractive alternative water source. However, there is not a clear framework for how to site and evaluate these alternative water resources in the presence of multiple conflicting water uses and diverse stakeholders. We build on existing scenario analyses of reclaimed water used for thermoelectric power plant cooling in the greater Chicago, Illinois area, proposing a multi-objective decision support framework. Variables considered within the framework include different power plant cooling designs (i.e., open loop versus recirculating), thermal variances from environmental flow laws, and the location and extent to which different plants are considered for alternative water sources. The framework shows tradeoffs among cost of the water sources, performance considerations such as the reliability and availability of the water, and institutional barriers such as water rights considerations. Overall, the decision support framework seeks to promote a more adaptable water and energy system while considering environmental and legal factors of various allocation schemes.
