Description:

Objective:

We are working toward a long-term water resource management plan that includes reuse of treated wastewater. In this project we will work to:

The water resource management strategies will consider the interests of local water users and the interests of water suppliers, the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC; responsible for water reclamation), the local government, and nongovernmental organizations (NGOs). Our objective is to build a decision support system that balances interests of stakeholders to maximize the social, environmental, and economic welfare of the local society. To meet the objective, this multi-objective decision model must be able to identify water reuse opportunities, prioritize these water reuse opportunities by cost factor, and optimize the allocation of urban water resources.

Progress Summary:

Based on current water use patterns and future water supply and demand projections for Northeast Illinois, it is likely there will be a future water shortage in the Chicago area. Reuse of treated wastewater can help address future water shortages, but a variety of issues will influence potential reuse. These issues include regulatory, policy, perception, and economic concerns.

Our case study of wastewater reuse potential near the MWRDGC Kirie facility demonstrates that wastewater reuse can be economical. The location of potential users relative to the source of treated wastewater, and the amount of water the potential users will need, determine supply costs. Water reuse supply costs are primarily a function of flow rate and pipeline length. These relationships are specific to each location.

Wastewater reuse scenarios in urban and suburban settings are different. Urban settings feature industrial clusters, relatively shorter pipeline distances, and high costs associated with installing a secondary distribution system in an urban setting. Suburban settings feature longer distances, fewer industrial clusters, and greater potential for irrigation of open spaces.

Perhaps the greatest barrier to reuse is associated with changing current practice and the potential for increased human exposure to waterborne pathogens.

Future Activities:

The major activity for the coming year is to complete the optimization model to assess wastewater reuse by industry in the Chicago area.

In addition, we will complete the regional wastewater reuse case study with the Fox Metro Water Reclamation District near Aurora, IL. The current most likely path to successful wastewater reuse at that location appears to involve a cooperative effort among the local park district, a major local industry, and the water reclamation district.

We will also complete assessment of potential economic benefits associated with incorporating a heat pump into a wastewater reuse system. We believe that an integrated water and energy recovery system holds great promise.

Finally, we are exploring a collaborative effort with the Illinois Center for Food Safety and Technology to work with the regional food industry to promote water reuse. The regional food industry, an important segment of the local economy, uses large volumes of water relative to their level of economic activity. They have expressed an interest in working with us to develop a more sustainable model for their industry.
