Population growth and industrial development have led to increasing groundwater withdrawals in the Chicago region. In some areas, groundwater is withdrawn at a rate that exceeds the recharge rate, leading to decreasing yields, increasing pumping demands, increasing salinity, and the search for alternative water sources, all of which increase the cost of providing water.
The Chicago region’s comprehensive plan includes a recommendation to coordinate and conserve shared water supply resources. Regional data on long-term water demand and recent water rate data help us do this, but have not been available – until now.
CMAP and Illinois-Indiana Sea Grant developed this critical water data for northeastern Illinois using water withdrawal data from the Illinois Water Inventory Program and collecting detailed rate data directly from municipalities.
The two final products, now publicly available on the CMAP Data Hub, include past water use and demand forecasts and water and sewer rate data for each community utility allowing anyone to understand their community’s water needs.
How can your community use the data?
- Examine trends and price signals.
- Incorporate forecasted data into local plans.
- Assess equity and affordability.
- Track performance.
- Communicate the value of water.
