The Autonomous Alpine Town
Transparent supply routes and autonomous, automated power and water supply – the Immenstadt public utility company in the Allgäu region relies on these and has done so with WAGO since 2009. Automation and telecontrol technology make this possible and clarify the potential for expansion and savings at the same time.
Over 14,000 residents, 30 square miles (80 km²), all at 2,400 feet (730 m) above sea level. Immenstadt in the Oberallgäu district of Swabia is a tranquil locale. But it would be a mistake to assume that time stands still in this idyllic Alpine town – the Immenstadt public utility company, a municipally owned and operated enterprise, is focusing on sustainable technology for municipal energy management and the distribution of district heating, as well as for the water supply, wastewater management and even flood control.
“The modular WAGO I/O-System simplifies plant control and system monitoring. It improves the energy management, reduces the calculation effort for the energy supply and makes it possible to integrate remote stations into the network smoothly,” says Paul Müller of ETM Elektro- und Systemtechnik in summary. His company is handling the planning on site as the system integrator.
But what specific technical products does this involve? “To be exact, since 2009 we have been using the 750-841/-881 Controllers and the PFC200, as well as the 750-652 Serial Interface,” says Paul Müller, listing the products in detail. A total of 45 systems have been equipped with this technology to date: 18 water supply stations, 13 wastewater plants, five systems belonging to the building management of the public utility company, three for flood control measures, five in district heating and one drinking water power plant.
