water extraction

Water is precious. To enable us to access it, high-performance submersible borehole pumps are deployed in wells and waterworks. They also play an important role in the refurbishment of municipal piping systems in cities around the globe.

New York

Outstanding performance in the mega-city

More than half of New York’s drinking water is conveyed to the city via the Rondout-West Branch Tunnel. Measuring 71 kilometres in length, it supplies up to 37 cubic metres of drinking water per second from Ulster County via a natural incline. As a result of geological conditions, the tunnel was losing up to 130 million litres of drinking water a day through leaks under the Hudson River. To enable the tunnel to be pumped empty for repairs in as short a time as possible, KSB supplied the most powerful single-entry submersible borehole pumps that our company has ever produced. The pumps are made from corrosion-resistant stainless steel. Each of the five pump sets is equipped with a 2,000-kilowatt electric motor and handles around 2,000 cubic metres per hour.
