Temperature sensors measure relief activity


As part of the General Drainage Plan (GDP) revision of the municipality of Uzwil SG, HOLINGER uses low-cost temperature sensors to monitor the relief activity of stormwater overflow structures and basins. Since April 2020, area-wide information on the duration and frequency of discharge has been collected for 16 discharge structures. The measurements provide important information that can be used to optimise the operation of storm relief structures, which in turn contributes to improving river water quality.
