Case Study: Metropolitan Sewer District of Greater Cincinnati achieves real-time industrial pretreatment intelligence with KETOS SHIELD

Metropolitan Sewer District of Greater Cincinnati monitors 30+ parameters with KETOS

The Metropolitan Sewer District of Greater Cincinnati (MSD) sought to extend its water quality monitoring beyond simple treatment compliance. The challenge was to gain better visibility into the specific contributions of industrial dischargers within its collection system, particularly regarding nitrogen loads, which was difficult with traditional manual sampling methods. To address this, MSD utilized the KETOS SHIELD platform from vendor KETOS.

KETOS implemented a solution using dual-point SHIELD monitoring at the facility's raw influent and post-treatment effluent. This provided MSD with real-time, lab-accurate data on parameters like nitrogen species, enabling them to characterize industrial contributions and build a defensible record for surcharge programs. The result was that the same KETOS platform used for compliance was successfully extended to provide continuous industrial pretreatment intelligence, turning operational data into actionable insights.
