RWW Rheinisch-Westfälische Wasserwerksgesellschaft mbH - part of Westenergie was awarded as the 2023 TOP local supplier in the water segment for quality, transparency and sustainability by the "energieverbraucherportal". A quality seal that documents the conscious use of water as a resource and is assigned to local suppliers that are particularly consumer-friendly, service-oriented and innovative.

RWW's "Wasserheld" is also service-oriented and innovative, a project that has now gone "live" with a roll-out. The aim of the project is to provide industrial customers (and in the future also private customers) with information on water consumption via an app and to alert them to possible leaks. Of course, this is also linked to the goal of motivating consumers to make conscious and sustainable use of the valuable resource "drinking water".

According to statistics, a water pipe bursts every 30 seconds in Germany because of aging, frost damage, etc. Water pipe damage often goes unnoticed for a long time. In order to be able to detect leaks at an early stage and minimize the damage, "Wasserheld" was created. This cloud solution works very simply. Customers can monitor their water consumption via app or web interface. In the event of major deviations in consumption, the app generates an automatic warning message.

To makes this work technically, the data of the respective water meter must be transferred to the RWW cloud, this means the water meters must first be upgraded to remote readability. The customers themselves without much effort can do this quickly and easily. All they need to do is plug a radio adapter onto the water meter, which sends the meter values to WEPTECH's SWAN NB-IoT gateway using the standardized wM-Bus protocol (EN 13757-4).

The SWAN is a powerful, battery-powered gateway that transmits the received meter data at defined intervals secured via LTE Cat. NB1 (Narrow Band IOT) to the RWW cloud platform. Using the Wasserheld app (or via web interface), customers can monitor their consumption on a daily basis. The ability to read meters remotely means that complicated manual meter reading by the supplier will no longer be necessary in the future. In addition, a corresponding alarm message is automatically generated in case of strongly deviating values, which indicates a possible leakage. Overall, the "Wasserheld" offers a valuable benefit to all those involved and thus represents an innovative solution for the sustainable use of drinking water as a resource, according to Product Manager Michael Fech from RWW.
