Everything Flows

Systems to supply clean drinking water to entire regions are infrastructural masterpieces, in which an extraordinary number of facilities need to work together. If the supply chain is interrupted at any point, this inconveniences the water customers at the very least; at worst, it can actually be hazardous. An intelligent power supply helps to maintain an uninterrupted water supply.

At a Glance

  • The communication capability of the Pro 2 Power Supply allows monitoring of connected loads.
  • These data can be used to detect anomalies and trigger a service call before a system failure occurs.
  • In this way, the Pro 2 Power Supply provides an important component in predictive maintenance for the Norwegian water supply.

Pump works, booster stations, valve stations, water tanks, reservoirs etc. – before this life-giving liquid reaches the consumer, it has often traveled a long way from its source. Nowadays in Europe, all of the distribution systems listed above are often at least partially automated and supplied with electricity. The water network infrastructure is often distributed across a wide geographic area, and the connection of remote stations is not always optimal in terms of the traffic. Maintenance of such facilities often takes place according to fixed schedules and can take a lot of time. Service technicians may spend many hours traveling to perform required inspections or, in the case of emergencies, to reach the location of a problem. For example, local power outages test consumers’ patience: The affected equipment first needs to be located, and then maintenance personnel have to travel there – often just to manually reset a fuse.

Beautiful Country – Long Distances

Norway has is one of the largest countries in Europe in terms of land area – but is also very sparsely populated. Water distribution networks vary greatly in length and coverage; large distances between distribution facilities are the rule in municipal water supply systems there. The operators want to gradually increase the level of automation in their systems. The potential for remote monitoring of distant pumping stations or tanks and reservoirs is the primary area where the operators hope to achieve greater operating efficiency and a massive reduction in maintenance costs. One important step in this direction consists in rethinking the power supply from the ground up.
