The pumping station in Uetendorf near Thun, Switzerland, went into operation in March 2014, and pumps 25,000 l/min of water from a depth of 19 m.
40% of the drinking water in Switzerland is pumped out of groundwater streams. To guarantee an adequate long-term supply of drinking water in the greater region around the city of Thun, the public company WARET (Wasserversorgung Region Thun AG) was established.
The water catchments in the gravel layer near Uetendorf consists of a so-called horizontal filter well with a central well shaft of 5.0 m inner diameter. The pumped groundwater is supplied to around 100,000 people in five communities in the region, and is also partly supplied to the city of Bern.
ROMAG provided special constructions in stainless steel for this large well. The scope of supply was glazed and walkable covers (Ø 5 m), large doors, glazed guardrails and windows.
