The municipality of Schwoich operated a water supply system without remote monitoring but that was about to change. Their requirements for the future were the following:

• digital monitoring of elevated tanks, springs and water meters,
• continuous network monitoring for leak detection and
• partial monitoring of the existing hydrants.

In order to avoid costly and time-consuming electrical installation and excavation operations, a data logger system without an external power supply was to be set up for this project. In addition, an interface had to be created for data exchange with an existing system provider.

The customer decided to use the Hawle.live BOX to digitally monitor the elevated tanks. This enables them to call up the fill level and the water meters digitally at any time. They also employed the i::scan product for turbidity. For this, a battery pack with a photovoltaic module was also installed to create greater independence in terms of power consumption.

Ten state-of-the-art NB-IoT correlation loggers have now been installed to monitor the network permanently. These are equipped with a SIM card and enable leaks to be located conveniently from the office. For this purpose, technicians laid out the terminal devices in a defined zone. During the night, these devices receive potential leak sounds and locate them by means of correlation. Any potential leaks are displayed visually and geographically on a platform (integration into the Hawle.live APP is planned). In order to have an optimum overview of the hydrants as well, they are now fitted with the Hawle.live CAP. This means that it is possible to monitor the hydrants remotely at any time and from any location.
