# Sensor for detecting pollutants in incoming water (reference 397771)

The Subotica water and sewerage utility has an open goods procurement for a sensor to determine pollutants in incoming water. The source snapshot classifies it as CPV 35125100 (sensors). The exact portal page returned HTTP 500, so the pollutant types, sensor specifications, quantity, value and installation/delivery terms are unavailable. The snapshot gives 21 October 2026 as the deadline date and records 08:00 UTC; the local portal cutoff could not be checked.
