Security for Water Supply

SPANGLER – the Plus in Supply Security.

When techniques from other fields are used in technical revolutions, it is called technology transfer. Together with our customers, we were able to achieve such a technology transfer at the waterworks of the municipality of Mühlhausen. The starting situation was the municipality’s requirement to secure the waterworks against the failure of the public power grid.

Initial Situation and Challenge

The first construction phase of the Mühlhausen waterworks was implemented many years ago with a forward-thinking approach. With the facilities available at that time, in the event of a power failure, the population had access to the water stored in the elevated tanks. A technician then had to be on-site to manually start the emergency generator and ensure the water supply. To simplify this laborious procedure and increase supply security, a stationary emergency generator has now been integrated into the waterworks.

Innovative Solution

The stationary emergency generator, with a capacity of 250 kVA, automatically detects a grid failure and starts independently. The pumping station is supplied with energy with minimal delay, and the water supply automatically resumes. Our contribution is thus a significant advantage of this system, as we were able to fully integrate the factory-prepared components of the aggregate into the existing control cabinet system.

Technical Modernization

Another step in this project was the conversion of the network form to TN. This modernization was necessary to bring the feed-in up to date. This measure not only increases the safety and reliability of the facilities but also ensures that the waterworks are prepared for future challenges.

Future Outlook

Uninterruptible power supplies are widespread in other critical areas. Hospitals, civil protection buildings, and other critical infrastructures already rely on secure supplies. Waterworks as well are increasingly included in the circle of critical infrastructures, and the issue of supply security is gaining more and more importance. At Spangler, it is therefore assumed that this implemented solution will become the standard in the future.
