The polder Söllingen/Greffern was built for flood protection on the upper Rhine below Iffezheim. In order to control, monitor and document its operation with a minimum of personnel, the Greffern control centre uses the HydroDat® V8 process-control system from HST Hydro-Systemtechnik. All external constructions are connected to the control system via TeleMatic remote-control stations.

The high demands on the new system (e.g. the linking of a number of external stations) prompted the operators to choose the tried and tested PCS HydroDat V8.

Because a new neutralising unit was required, the opportunity was taken to modernise the technical equipment at the Queckborn waterworks belonging to the Stadtwerke Giessen AG (municipal works). In addition to a redundantly structured automation level with embedded control systems interlinked by Ethernet LWL, the HST process-control system HydroDat® V8 was installed.

Steinhagen/Wermelskirchen: around 37000 people live in the town of Wermelskirchen east of Cologne. Not all of these live in the town itself, but in a fairly densely populated rural area covering about 75 square kilometres. The reliable disposal of the waste water from all the households connected to the municipal sewerage system is therefore a challenge to the planners of the local sewage works. For the recent expansion of the municipal network, the town decided to install modern control technology which is compatible not only with existing systems but also with state-of-the-art communications and remote-control systems.

Today, the transmission of data from decentralised data-collecting stations generally takes place via the public telephone network (ISDN or analog) using permanent connections or radio-telephone networks. Due to the increasingly widespread network of GSM networks, this method of communication is also becoming more important in the field of remote data transmission.

As operator of one of the most extensive networks in Germany, the municipal sewerage authority in Frankfurt am Main has installed the innovative process-control system HydroDat® V8 and the web-based process-monitoring and control system HST TeleMatic as part of its modernisation program for monitoring special constructions in the sewerage system.

In Meinerzhagen, the municipal works have introduced the KANiO® Works Management System to improve their operating procedures. The system supports employees in organising and scheduling.
