Discover MWRD Wastewater Treatment Plant Tours across Cook County

Get a behind-the-scenes look at how Chicago’s wastewater and stormwater are cleaned, processed, and turned into safe water — through a tour of one of the region’s major water reclamation plants run by MWRD. These tours reveal vital infrastructure in action, showing how water is treated, resources recovered, and flooding prevented.
Why it’s special: MWRD treats water for millions of residents across Cook County. Visiting a plant gives rare insight into the massive, often invisible systems that keep the region’s water clean and safe.

History/Story of MWRD & Its Water Reclamation Plants

The MWRD has operated since 1889 (originally as the Sanitary District of Chicago), managing wastewater treatment, flood control, and environmental protection in the Chicago area. Over decades, they’ve built a network of water reclamation plants (WRPs) and pumping stations that process sewage and stormwater, treat water, and safeguard waterways and Lake Michigan. These plants have evolved into world-class facilities that not only treat wastewater, but also recover resources, manage storm events, and support local ecology. Wikipedia+2mwrd.org+2

Visiting Information

Hands-On Elements

Tours are mostly observational, but you may see treatment processes in action, examine water treatment equipment, and learn first-hand how wastewater becomes clean water. Some tours include staff-led demonstrations or explanations of treatment and resource recovery.

Photo/Video Policy

Photography is usually permitted in public visitor-accessible areas. Because these are working industrial facilities, there may be zones where photo or video is restricted — visitors must follow facility safety and security rules. Closed-toe shoes and long pants are required; no sandals or open footwear. mwrd.org+1

Souvenirs & Extras

• Educational materials about water treatment, resource recovery, and environmental impact

• Occasional free giveaways during open-house events (for example, native-plant seed packets or eco-education kits) when tours coincide with community outreach programs mwrd.org+1

• Access to virtual tours if you prefer online exploration over an in-person visit mwrd.org+1

Practical Info

Tours are by appointment only and must be requested at least 30 days in advance — this allows time for security clearances and waiver processing. Tours accept groups of 10–30 people, including school groups (from grade five and up) and adults. mwrd.org+1

Nearby

Because MWRD tours take place at different plants across Cook County, “nearby” depends on which plant you visit. Some plants are in Chicago, some in suburbs — many are accessible by car or public transit. Typical nearby amenities may include local parks, community centers, or suburban resources depending on plant location.

FAQs

Do I need to register or book in advance?

Yes — all in-person tours require advance booking (at least 30 days ahead) to allow time for security clearance, waivers, and group coordination.

Is the tour suitable for school groups or children?

Yes. Tours are open to school groups (from 5th grade upward) and include educational components. Plant staff often adapt explanations for younger audiences.

Are the tours always available?

No — tours may be canceled or postponed due to operational needs, public-health advisories, or safety considerations. Always confirm your booking in advance.

What should I wear or bring?

Closed-toe shoes and long pants are mandatory. Since it’s an industrial facility, weather-appropriate clothing is advised. Bring a government-issued ID if you are 18 or older (required for security).

Is there an option to take a virtual tour instead of visiting in person?

Yes. MWRD offers virtual tours of their water infrastructure and historical water-management projects — a good alternative if you’re unable to visit.
