Ecological Spanish contract for KSB

KSB Group is to supply numerous water extraction and transfer pumps for the water supply system of the city of Santander on the North Spanish coast. The order is for twenty pumps of different type series.

Four tubular casing pumps, each with a capacity of 3000 m3 of water per hour, extract the water from the reservoir fed by the river Ebro and transfer it to a storage tank situated at an altitude of thirty-eight metres. From there, four double-entry volute casing pumps type RDLO, each with a capacity of 2,940 m3 per hour, pump the water across the Cantabrian Mountains . After overcoming the geodetic altitude, the water, through force of gravity, continues its journey to Santander through a network of pipes.

The Ebro reservoir, a UNESCO-backed biosphere reserve, has a unique ecological system consisting of a great variety of plant and animal species. In order not to disturb the ecological balance of the reservoir, operators have to replenish the water taken out of the reservoir within the following three years, KSB says, and twelve additional high-performance pumps, installed in a total of four pumping stations, take care of this. They only start operating when the rivers feeding the reservoir hold so much water that there is no risk of the ecological balance being disturbed.
