Norway – Water meters – Water meters with remote reading and leak detection.

Background and current situation The Municipal Council of Sandefjord kommune undertited in matter 096/26 01.10.2026, amending the regulations on water and sewage fees, with the introduction of water meters to all subscribers. In connection with the approved implementation, there is a need for an agreement for water meters that covers the municipality ́s future needs. The current system has limited support for remote reading and monitoring. Therefore there is a need for a more up-to-date and operational-friendly meter system that provides better control, more stable automatic reading and a better basis for following-up subscribers. Description of need The municipality needs ultrasound meters for all subscribers, with remote reading with the use of NB-IoT as standard. The meters must be robust and suitable for use in different types of subscribers, both business and residence/holiday home. There is a central need for the meters to have functionality for leak detection before the meter, so that leaks on service pipes before the meters can be detected early. The system shall contribute to simpler operation and better control through automatic and stable collection of measurement data and alarm data. Technical and functional requirements The new system must support secure data flow and automatic transfer of measurement values and alarms. There is a need for signals for operations in the event of deviations and leaks, as well as access to history and analyses per water meter. The system ought to have a platform for reading and following-up the meters, as well as an option for integration with the municipality ́s fee system, pt Norkart. The need includes a system that, in total, provides better monitoring, early detection of leaks and a more efficient management of water meter data. Scope and phasing in The implementation shall be implemented gradually. The installation of water meters will start in buildings where alterations are made, as well as in new buildings. A new political issue shall later be presented, with a more detailed review of the execution and costs connected to the existing buildings by the end of 2026. The aim is for all households to install water meters under a four year period, but this depends on political decisions and budget.
