Work is starting on a $3 million project to rebuild a section of sewer near Graphic Packaging and the Kalamazoo Water Reclamation Plant. The existing design was built in the 1960s and is too large for current needs. It has drops that cause turbulence (splashing) in the wastewater flow, which can release hydrogen sulfide (H2S) into the air and may contribute to odors in the area. This project will replace the current sewer with an appropriately sized pipe. It will have a consistent grade so wastewater flows smoothly into the treatment plant, without any turbulence. The new design is also mechanically sealed to prevent air from escaping. Since 2019, the City has invested more than $15 million to address odors near the Wastewater Treatment Plant. Air quality sensors have been placed in the area, industrial air filters have been put into service, and a number of changes have been made to the treatment process. These investments have made a big difference, and the City remains committed to improving the air quality and reducing odors related to treatment and industrial activity in the area.
