NIVUS RAIN is a digital information service operated by NIVUS GmbH for local authorities. The operation includes the measuring network of heavy rain sensors for generating the heavy rain early warning, the water level and sewer sensors for monitoring, as well as special cloud systems that process the data in real time, generate information and make it available to users. The advantage is that measurement data can be used and offered across local authorities, maximising the benefits for everyone involved. At the same time, this allows a reduction in costs for all customers, as they do not have to set up the experts themselves.
