Precise inflow measurement for wastewater and rainwater with KANALIS and Q-Eye PSC

How GWF supports a UK water and sewage company with precise flow measurement for regulatory compliance and environmental protection.

Reliable operation of wastewater treatment plants depends not only on high-performing infrastructure, but also on precise measurement data. Especially in combined systems carrying both wastewater and stormwater, periods of heavy rainfall can push the system to its capacity limits, putting stress on infrastructure and the surrounding environment.

At a UK water and sewage company, these were exactly the conditions that had to be addressed. The facility serves around one million people and processes up to 2,500 liters per second. To run the plant efficiently and avoid spills into the river, a permanent inlet flow monitoring solution was required that meets UMON4 Environmental Agency compliance, carries MCERTS approval and connects to the local SCADA system, all without interrupting ongoing operations.

This reference case demonstrates how GWF implemented a precise and compliant measurement solution using KANALIS in multi-path mode and a customized Q-Eye PSC plug-in solution, monitored via connection to the local SCADA system. The focus is on the innovative sensor frame design for the distribution tower, the installation without operational interruption or rerouting, and the early detection of capacity limits to prevent emergency relief in the flow.
