The Association for Sewers and Waste Water (VKA) in Nidau is responsible for the waste water treatment plants from Port to Moeringen on the southern banks of Lake Bielersee. The Association manages several rainwater basins and pumping station. The Ipsach rainwater basin was built in the early 1990s. The unique feature is that this is a rainwater basin in a connected system. The receiving water cannot enter the lake by gravity but must be pumped into Lake Bielersee by four pumps of a combined discharge of 840 liters per second. The pumping station was repaired in the winter of 2011/2012.
Robust, transparent, accurate, fast, low maintenance and reliable for wastewater, raw wastewater and rainwater.
Precise drain throttle for heavily polluted waste water. The IDM flow measurement for full filling is the central element of the almost self-cleaning, remotely operated and highly precise pneumatic discharge control PNA. The reliable and never-tiring flap with pneumatic drive and the pinch valve react quickly to changing flows and conditions.
