The MWRD received its reporting certificate from the U.S. Environmental Protection Agency's WaterSense® for reporting 2025 annual data. The data helps the EPA track WaterSense's progress and achievements.

More than 9.9 trillion gallons of water have been saved since 2006. The MWRD actively promotes water conservation through education, outreach and community initiatives.

For example, the MWRD participates in Fix a Leak Week, encouraging residents to repair household leaks to prevent water waste. Additionally, the MWRD supports a rain barrel program, green infrastructure projects and public awareness campaigns to help protect our precious water resources.

MWRD earns Gold-Level recognition from American Water Works Association's Water Ambassador Program

The MWRD's commitment to public engagement has landed its Office of Public Affairs a Gold Level designation from the Illinois Section of the American Water Works Association's (ISAWWA's) Water Ambassador Program. This is the highest honor granted through the initiative. An award was presented on April 14 in Peoria, IL.

The Water Ambassador Program highlights organizations that go above and beyond in promoting water stewardship, and the Gold Level designation recognizes organizations that demonstrate exceptional commitment to water education, community engagement, and public outreach.

This recognition reflects the MWRD's efforts in delivering robust educational programming to schools, community groups, and civic organizations; offering public tours, open houses, and hands-on learning opportunities; developing accessible, multilingual outreach materials; supporting statewide water-awareness campaigns and professional development initiatives; and demonstrating leadership in public communications focused on water quality, infrastructure, and environmental protection.

Stormwater Partnerships available for local government

The MWRD can help local government organizations pay for the construction of stormwater infrastructure on public property in Cook County.

The program funds projects that address flooding through a variety of traditional engineering solutions including localized detention, upsizing critical storm sewers and culverts, pumping stations, establishing drainage ways, as well as green infrastructure. This infrastructure can reduce flooding and prevent damage to homes and businesses.

Throughout the year, the MWRD reviews applications and prioritizes projects for partnerships. The selected partner is responsible for their project's design, contract advertisement and award, acquiring any necessary property rights, construction, and long-term maintenance. There are four partnership programs offered on a regular basis.

Keep medications out of our water!

Medications can end up in waterways. This includes pet medications too!

These drugs can pass through our water reclamation plants (WRPs) and enter rivers and streams. This can harm fish, plant life and our waterways. Controlling what goes down the drain is an easy and effective way to protect the environment.

How you can help

You can help keep medications from entering our waterways by disposing of unwanted medicine properly.

• Never flush unused medications or toss expired medicines in the garbage.
• Take unused and expired medications to Cook County Prescription Drug Take Back Network locations.
• For over-the-counter products, monitor your supply. Store them in one spot in your home to avoid accidentally buying extras.

The MWRD is proud to play a role in collecting unwanted medicine and keeping our drains medicines free. Our boxes are located near the entrances at the Stickney, Calumet and O'Brien WRPs and in the lobby of the Barbara J. McGowan Main Office Building in Chicago. Do not leave medication outside the box. If a box is locked, please return during hours of operation or visit another location.

What is the key to pollution prevention when it comes to are Per- and Polyfluoroalkyl Substances (PFAS)?

Per- and polyfluoroalkyl substances (PFAS) are a group of manmade fluorinated compounds that are designed to be stable and have been in commercial use since the 1940s. The stability of the chemicals makes them difficult to degrade which is why they are often called "forever chemicals." PFAS are in commercial, consumer, and industrial products and and the U.S. Environmental Protection Agency (EPA) announced that they are widely present in the environment; nonstick cookware, cosmetics, sunscreens, washing clothes, and fire-fighting foams can introduce PFAS into the environment.

Like other water utilities across the U.S., the MWRD is addressing how best to manage PFAS in the water environment. The MWRD's seven water reclamation plants (WRPs) do not produce nor use PFAS but are passive receivers of these chemicals discharged to local sewers. As a result, wastewater can contain trace amounts of these chemicals from industrial, commercial and household sources. The MWRD's WRPs were not designed to remove these chemicals during the treatment process.

The key to pollution prevention is addressing the source of PFAS.

The MWRD is closely following and proceeding based on the developing science on the potential impacts of PFAS. The MWRD is also working to identify and reduce industrial discharges of PFAS, learning how the discharge from these sources can be reduced and encouraging federal and state regulators to focus on stopping these chemicals at the source. The MWRD's pretreatment program regulates industrial discharges to protect the treatment process and valuable resources the MWRD recovers.

Permanent Household Hazardous Waste (HHW) Collections

Dispose of your household chemicals responsibly and recycle your old computers.

• Tuesdays 7 am - Noon
• Thursdays 2 pm - 7 pm
• The first Saturday of every month 8 am - 3 pm

Household Hazardous Waste (HHW) may be dropped off at the City of Chicago's permanent Household Chemicals & Computer Recycling Facility at 1150 N. North Branch Street (two blocks east of the Kennedy Expressway at Division Street).

Household chemicals and computers often contain hazardous substances, such as lead, mercury, and PCBs (polychlorinated biphenyls) which can contaminate our air, soil and water. Through proper disposal methods or recycling, these hazardous substances are reprocessed and reused in an environmentally-responsible manner.

Coming soon! South Suburban College, 15800 State St., South Holland, will be the site of a new permanent HHW facility. Residents will be able to dispose of household chemicals, rechargeable batteries, oil-based paints, solvents, medications, fluorescent light bulbs, antifreeze, motor oil, gasoline, auto fluids, herbicides, pesticides, insecticides, aerosol cans and lawn, pool and hobby chemicals. This facility will be located next to the Center for Hard to Recycle Materials (CHaRM) Center where residents can dispose of electronics, polystyrene foam, clothing and textiles, personal healthcare equipment and general household recycling materials. CHaRM has taken in nearly 2.5 million pounds of materials. Read more.
