In this project we will develop a multi-objective decision model for urban water use, which can lay the foundation for a water reuse ordinance in the Chicago metropolitan area.
In the initial phase of the project, we will evaluate existing technological, economic, societal, and environmental incentives and barriers to wastewater reuse. Planning for sustainable water use must incorporate multiple and often conflicting objectives. Several objectives, for example, would seek to minimize costs for water treatment, wastewater treatment, water distribution, new dual distribution lines, and new treatment costs (such as chlorination). There could be multiple in-stream flow requirements for aeration, wastewater dilution and conveyance, habitat protection, transportation, and recreation. Energy aspects must be included, both for the existing hydroelectric plant and for energy requirements associated with treating water and wastewater and distributing water. There is also potential for energy recovery from the wastewater using heat pumps. An obvious objective of the model is to minimize water withdrawal from Lake Michigan. Finally, the decision model must be structured to minimize potential risks associated with wastewater reuse, and to maximize public acceptance of reuse applications. The decision model will be used to understand the relative weights associated with these issues, and plan effective, long-term sustainable water use.
Short-term success of the project can be defined in terms of the model development. Long-term success can be measured in terms of the volume of wastewater reuse, decreased withdrawal from Lake Michigan, energy savings, and their associated economic benefits.
