Flood warning during construction

Construction work to sewage systems in dense urban areas is complicated.


During a renovation work in Dortmund there was a risk of larger amounts of water from the further on upstream drains entering the location where the maintenance operations took place. A temporary bypass was far too costly.


In order to prevent risks to persons working in the drains, sensors have been placed in the upstream drains. TeleControlNet alarmed the maintenance workers for upcoming water. The data transfer was performed by GPRS with a live heartbeat to secure the connection.
