What is this project about?

This project creates a connection allowing Chicago to provide drinking water to residents of Joliet, Channahon, Crest Hill, Minooka, Romeoville, and Shorewood, that have joined together to form the new Grand Prairie Water Commission (GPWC). These communities’ current water source – an underground aquifer that has served the region for more than 100 years – is rapidly depleting and by 2030 will no longer provide enough water to meet residents’ needs. To address this situation, the GPWC has entered into an agreement with Chicago to obtain treated Lake Michigan water. Joliet is leading the project on behalf of GPWC.

Why Chicago?
Through its Department of Water Management (DWM), Chicago provides treated Lake Michigan water to 5.3 million people in northeastern Illinois through a water system with a capacity of nearly 2.1 billion gallons per day. As a steward of this vital resource, Chicago wishes to assist Joliet to ensure its continued access to clean drinking water. In addition, the agreement with Joliet will provide additional revenue to Chicago’s Water Fund, which will help maintain our water system and reduce costs to Chicago residents.

Why Durkin Park?    

DWM’s Southwest Pumping Station adjacent to Durkin Park is the closest point where the GPWC can connect to Chicago’s water system. To achieve this, the project will construct a new water connection at that location.

When will the construction begin, and how long will it last? Which areas of Durkin Park will be affected? During construction, how will residents' access to recreational space be ensured?

The project (see graphic above) includes above ground additions -- shown in yellow and red -- on the Southwest Pumping Station (SWPS) site, and construction of an underground water reservoir on the south side of Durkin Park (shown in blue). 

Initial construction begins in 2025 on the SWPS site and does not affect Durkin Park. In 2026, construction begins on the south side of Durkin Park and is expected to last approximately two years, during which that area of the park will be unavailable (the rest of the park will remain open).

To minimize the inconvenience and continue serving the community, Joliet will pay the Chicago Park District to construct improvements at nearby parks (Rainey, Bogan and Scottsdale) that will be completed before work begins at Durkin Park. Once construction of the water reservoir underneath Durkin Park is complete, the park surface will be restored and returned to recreational use, along with the newly added amenities at surrounding parks.

How will Durkin Park be restored after construction and how will the community benefit?

Once construction of the water reservoir underneath Durkin Park is complete, the park surface above will be restored with natural grass turf (based on community input received by the Chicago Park District) and returned to recreational use, together with the newly added park amenities at Durkin and surrounding parks.

How will residents be kept informed about construction at the Park?
In partnership with 18^th Ward Alderman Derrick Curtis’ office, DWM will host community meetings and provide emailed updates throughout the construction process. Residents are invited to sign up for updates by providing their email address at our community meetings or through the web pages that DWM and the Chicago Park District will maintain on the Durkin Park project to keep residents informed.

Have questions or want more information? We want to hear from you!
