Calumet Water Reclamation Plant

Chicago's commercial industrial category holds 73 listings, which is enough that scrolling straight through isn't the fastest path to a call. Most people narrow by zip instead: 60609 has the most entries at 7, followed by clusters in 60607 and 60638, so starting near your own address usually trims the list to something manageable fast.

Every listing here includes a phone number, and most, 69 of the 73, also link to a website, so you can usually check services or hours before dialing. None of these carry a Sponsored tag yet, since that feature hasn't turned on for this category in Chicago, meaning the order you see is just how the records sit, not a paid slot. Call two or three that match what you need and compare directly. And if you run one of these companies and something looks off, like a bad phone digit or a missing site, you can claim the listing and correct it yourself.
