Substantial savings
实实在在的节省
Wells, waterworks and pumping stations are controlled by remote from a central control room to eliminate the need for onsite manning. This has had a significant impact on operating costs, reducing staff from about 160 to 100 and enabling the customer to make substantial savings in annual expenditure.

The quality of the drinking water has also been secured by greater process transparency, made possible by the real-time exchange of data between waterworks.

“We set the target of cutting overheads and creating a water management system that would enable us to predict demand at all plants 24 hours in advance,” says Jens-Uwe Klinger, engineer at Berliner Wasserbetriebe.
