| safe_image for MWRD monitoring for COVID-19 [paycount of 5] MWRD's Report Dennis DeBruler: The photo is of which plant? Hi Dennis , this is our Calumet Water Reclamation Plant that has been in operation since 1922. This plant serves residents and businesses in the southern portion of Cook County. At the time of its opening, the 16-mile Calumet-Sag Channel had just become operational. By 1928, the plant served a population of 155,000. At present the plant’s service population is over one million people in an area of about 300 square miles. Learn more here  |
The communities downstream of Chicago were not happy with Chicago reversing the flow of the river and dumping their sewage and stock yard wastes into their source of drinking water, including St. Louis. MWRD's predecessor finally decided to stop paying for lawyers and to start paying for concrete. Years ago I read that the sanitation district helped pioneer large scale water reclamation. In fact, the Stickney Plant is still the worlds largest. (History1, History2) (It is interesting how the terminology has been "cleaned up" over the decades. When I was a kid, it was "sewage treatment," then it was "waste water treatment," now it is "water reclamation.")

U.S. Sen. Dick Durbin noted that Chicago was the last major city in the U.S. to disinfect its treated wastewater.Note the implication that Chicago has been uncivilized until the 21st century. So Chicago was one of the first metropolitan areas to build sewage treatment plants, but one of the last to kill the bacteria in its water output.
"This disinfection facility now brings Chicago into the civilized world when it comes to the treatment of sewage and the discharge," Durbin said. (Tribune)
Update: this plant uses the old technique of adding chlorine then removing the chlorine. The O'Brian Plant uses a new technique of ultraviolet radiation.

| MWRD posted For immediate release October 28, 2020 MWRD’s dedicated essential service earns platinum praise Despite the unpredictable nature of stormwater running off streets and sidewalks and wastewater funneling from homes, businesses and industrial corridors, the Metropolitan Water Reclamation District of Greater Chicago (MWRD) has again achieved the highest standards for transforming billions of gallons of wastewater into clean water and protecting area waterways. The National Association of Clean Water Agencies (NACWA) recognized the MWRD with six Platinum Peak Performance Awards for at least five consecutive years of meeting stringent permit guidelines at six MWRD water reclamation plants (WRPs), including the Calumet WRP, which earned platinum honors for meeting full compliance for 28 consecutive years. “Thank you to our innovative staff who work the front lines every day to protect the quality of our region’s water and reclaim it to benefit our environment,” said MWRD Vice President Barbara McGowan. “Although these awards commemorate our work in 2019, it is this same staff who we applaud in 2020 as heroes for sacrificing so much to come into work each day to manage our region’s wastewater and improve the quality of life for residents and the environment around them.” The annual awards honor treatment plants for meeting 100 percent compliance of National Pollutant Discharge Elimination System (NPDES) permits. The MWRD was lauded with platinum status at six WRPs for achieving 100 percent compliance for at least five consecutive years at each. The following facilities have earned Platinum status: • Calumet Water Reclamation Plant, Chicago, 28 years • Lemont Water Reclamation Plant, Lemont, 23 years • James C. Kirie Water Reclamation Plant, Des Plaines, 15 years • O’Brien Water Reclamation Plant, Skokie, 14 years • Hanover Park Water Reclamation Plant, Hanover Park, 12 years • John E. Egan Water Reclamation Plant, Schaumburg, 6 years The Calumet WRP, which treated more than 300 million gallons per day in 2019, was placed into service in 1922, followed by the O'Brien WRP in 1928. The MWRD treated more than 536 billion gallons of water in 2019, or about 1.47 billion gallons of water per day. More intense rain events combined with impervious pavement, a flat terrain and increasing demand to shelter the region from pollution all make the MWRD’s around-the-clock service essential to protecting the public health and the local water environment. Throughout the COVID-19 pandemic the MWRD continues to provide critically important water reclamation operations and stormwater management services to ensure the region’s wastewater is cleaned and that public health and the environment are protected. “We are honored to receive this platinum recognition from the National Association of Clean Water Agencies,” said MWRD Commissioner Mariyana Spyropoulos. “It serves as reminder of the important work of our Maintenance and Operations staff, pollution control teams and the Industrial Waste Division who ensure clean water for our environment no matter what flows their way.” In addition to its role as the regional stormwater authority for Cook County, the MWRD treats wastewater for residents and businesses for an equivalent population of 10.35 million people across an 882-square-mile area that includes Chicago and 128 suburban communities. The MWRD’s treatment process is protected by a pretreatment program to guard against hazardous substances and toxic chemicals. The MWRD routinely monitors industries and non-residential sources to assure that wastes are disposed of in an environmentally responsible and lawful manner. NACWA officials honored water utilities Oct. 28 during a presentation recorded in Washington, D.C. “Our public utility members are the backbone of the communities they serve, providing safe, reliable access to clean water services day‐in and day‐out. The Peak Performance Award ceremony is our chance to shine a national spotlight on those outstanding clean water utilities that have demonstrated operational excellence with no more than five permit violations in a calendar year, and, for our Gold and Platinum Award winners, zero violations,” said Adam Krantz, Chief Executive Officer of NACWA. “These utilities represent the top performers in the whole country and go above and beyond in their mission to protect public health and the environment. On behalf of NACWA’s Board of Directors, I extend my congratulations and gratitude to all this year’s award winners and I thank them for their service and their incredible compliance with increasingly rigid Clean Water Act standards. This year has seen unprecedented challenges in the wake of the pandemic, and the Peak Performance Award winners have more than risen to the occasion.” |

For immediate releaseSeptember 27, 2022Cal-Sag Channel, Calumet Water Reclamation Plant turn 100MWRD engineering achievements reversed flow of Calumet River system and introduced wastewater treatment to protect public health and water qualityWithin the span of a month in 1922, the Metropolitan Water Reclamation District of Greater Chicago (MWRD) -- then known as the Sanitary District of Chicago -- completed two monumental engineering feats to protect the health of the region and local water quality. A century later, the Calumet Water Reclamation Plant (WRP), Cal-Sag Channel, and reversal of the Calumet River system remain as pillars supporting public health and regional water environment.The MWRD will mark this occasion at its 10th Annual Sustainability Summit to be held at the Ford Calumet Environmental Center, 11555 S. Stony Island Ave. in Chicago, on Friday, Oct. 21 at 10 a.m. The 100th Anniversary of the Calumet Water Reclamation Plant (WRP) and Cal-Sag Channel will be highlighted among several presentations, a photo exhibit and discussion. Members of the MWRD’s first Community Partnership Council will be announced to promote community engagement within the communities the Calumet WRP serves. For more information on the Sustainability Summit, visit https://mwrd.org/10th-annual-sustainability-summit.After 11 years of construction, the gates at the Blue Island Lock on the Little Calumet River were opened on Aug. 18, 1922, diverting water to flow into the new Cal-Sag Channel for the first time. By Aug. 26, the Cal-Sag was fully operational. This action began the process to allow the MWRD to reverse the flow of the Little Calumet River west away from Lake Michigan, protecting the supply of drinking water and providing integral drainage to shelter and enhance the Far South Side.A few weeks later on Sept. 11, 1922, the MWRD completed construction of the Calumet WRP, 400 E. 130th St., Chicago. The new facility implemented emerging treatment technology that could transform wastewater from across the area into clean water.Today, the Calumet WRP is the longest-tenured MWRD water reclamation plant, serving more than 970,000 people each day from Chicago and 48 surrounding suburbs and providing around-the-clock services. The Calumet WRP can treat up to 450 million gallons of water each day, generating renewable energy and recovering vital resources to protect the planet and taxpayers. In addition to building the plant and digging the 16-mile Cal-Sag Channel, the MWRD built 6 other WRPs and nearly 184 miles of intercepting sewers to convey water from municipal sewers to its treatment plants.“This September we recognized 100 years of service, innovation and ingenuity at our Calumet Water Reclamation Plant and the work of our predecessors to construct the Cal-Sag Channel,” said MWRD President Kari K. Steele. “These measures that we often take for granted have had a profound impact on our way of life and today bolster our homes and businesses and keep our water environment safe.”The MWRD reversed the Chicago River through the construction of the Chicago Sanitary and Ship Canal (1900) and reversed the North Branch of the Chicago River through the construction of North Shore Channel (1910). But as the rest of the Chicago River reversed, the Calumet River was still flowing out to Lake Michigan, causing concern for waterborne illness and polluted water flowing out to the source of the region’s drinking water in Lake Michigan. Like the Sanitary and Ship Canal, the MWRD discovered the Calumet River system could also flow west by building a new canal that allowed gravity to funnel water through the subcontinental divide away from the Great Lakes toward the Mississippi River Basin.The 16-mile Cal-Sag Channel continues serving as the link to keep water flowing west, connecting the Calumet River system to the Chicago Sanitary and Ship Canal and downstream to the Des Plaines River, Illinois River and Mississippi River to the Gulf of Mexico. Today it is a thriving waterway attracting a surging population of fish, birds and recreation, and its construction generated a boom of economic opportunity, helping establish towns and attract residents, commerce and community life.“We celebrate the work of those before us who introduced transformative environmental protections which lead to recreational opportunities, industrial growth, and community and economic development throughout the region,” said MWRD Commissioner Kimberly du Buclet. “Our region has come a long way and we are still pursuing an even better quality of life for the residents that live and work here.”The introduction of wastewater treatment at the Calumet Water Reclamation Plant (top left and right) and Cal-Sag Channel (bottom left and right) proved critical to protecting the Chicago area’s public health and its environment altered the landscape of the region and established Chicago and the Southland region as a thriving metropolis destined for economic vibrance.This article is also posted at https://mwrd.org/cal-sag-channel-calumet-water...

The first plant was built in 1922 and was north of 125th Street. I'm not sure, but trying to line up the aerials, it looks like none of this plant left in existence; it looks like there are other buildings present at this old site, now, but I'm not sure if they were part of the original plant. There was also a Calumet Sewage Pumping Station to the west that served it. It's located on South Michigan Avenue between 124th Place and 125th Place, and still in existence, though, I think it went out of regular service after the construction of the new plant.
ReplyDeleteThe original part of the existing complex was then completed in 1936 directly south of 126th Avenue, and is still in existence, though expanded. This site consolidated the pumping station (called Calumet PLANT Pumping Station) and treatment works on the same site. I think the Calumet SEWAGE Pumping Station across the tracks on Michigan is used for back-up during wet weather or something, because it's still standing and maintained.
If someone can find some old maps of this area between 1922 and now, that would help a bit more to visualize this. But I think you may have all three sites pictured here.
