Despite cancellation, Chicago River Swim and Big Jump highlight revitalization of the Chicago River

Although the Chicago River Swim was canceled after a weekend of heavy rainfall and lightning, the Big Jump was held on Sept. 18 and both events still raised critical funds for ALS research and swim lessons and introduced hundreds of people to a revitalized Chicago River. Officials made the difficult decision to cancel the race after monitoring the weather and river conditions on Sept. 20. The National Weather Service issued a flood watch due to excessive rainfall. The MWRD issued an Overflow Action Alert early Saturday, reinforcing the need for water conservation to help minimize strain on the sewer system.

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 and 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 project design, contract advertisement and award, acquiring necessary property rights, construction and long-term maintenance. There are four partnership programs offered on a regular basis.

Stormwater Central: Online portal maps stormwater management storage progress

A new hub for mapping data and insight into the work of the MWRD Stormwater Management Program is live and accessible to the public.

stormwater central banner

Available at this link, the new site provides a window into the MWRD's stormwater management work in building resilience across Cook County. The interactive portal serves as an integrated hub for mapping data, project information and insights into how the MWRD is working to reduce flooding and manage stormwater across Cook County.

The hub includes the Stormwater Project and Data Explorer, which maps data on past and ongoing MWRD stormwater management projects. Visitors can learn more about projects occurring in their communities or across Cook County, assess stormwater volume capture, review MWRD goals for capturing more volume and track progress as projects are implemented across watersheds.

Stormwater Project and Data Explorer

Since 2004, the MWRD has served as the regional authority for stormwater management in Cook County. As the impacts of climate change intensify, the MWRD has overseen a countywide effort to manage stormwater runoff, reduce flooding, improve the health of area waterways and protect the source of drinking water in Lake Michigan.

Over that time, the MWRD has implemented new policies, strategies and partnerships to manage increasingly intense and unpredictable storms. In just over a decade since receiving local authority in 2014, the MWRD has completed more than 230 projects that protect more than 17,000 homes, businesses and other buildings from flooding.

Local governments and public agencies in Cook County can apply to the MWRD for help funding stormwater projects. The portal documents this growing map of projects after years of meticulous data management. Additional data is available upon request.

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 down the drain or toss them 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 and store them in one spot in your home to avoid accidentally buying extras. Never flush them down the toilet.

The MWRD is proud to play a role in collecting unwanted medicine and keeping our drains medicine 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 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 called "forever chemicals." PFAS are in commercial, consumer and industrial products, and the U.S. Environmental Protection Agency (EPA) announced that they are widely present in the environment; nonstick cookware, cosmetics, sunscreens, washing clothes and firefighting 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 do not produce or use PFAS but are passive receivers of these chemicals after they are 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.

Tips to prepare your home for excess water

Read our "Green Neighbor Guide"

""

It's never too soon to work on projects that can make your home more resilient to stormwater.

Some actions can be as simple as not over-fertilizing your lawn and garden, installing a rain barrel or planting a native tree. No matter what action you choose, the MWRD "Green Neighbor Guide" can help. It gives instructions on stormwater management projects that you can install on your property. For example, detailed instructions are offered for disconnecting downspouts; installing rain barrels or cisterns to capture stormwater for reuse; installing dry wells and rain gardens to allow stormwater to filter into the ground; and replacing asphalt and concrete surfaces with permeable paving to reduce stormwater runoff.

Watch our YouTube video to see how a rain barrel is installed.
