Hamar and Ringsaker digitalise water metering on Divako.

One platform, two municipalities

Hamar and Ringsaker have chosen to digitalise water metering together, on a single technical platform built on Divako. Rather than run two separate projects, the neighbouring municipalities share one network, one data pipeline and one operational view – one of the more ambitious municipal IoT rollouts in Norway, and a template for how regions can pool infrastructure instead of duplicating it.

The first phase replaces roughly 25,000 analogue and mechanical meters with digital ultrasonic units. The agreement does not stop there: it is structured to extend to almost every residence and commercial building across both municipalities, growing into a single IoT network of thousands of measurement points.

Meters built for the long run

The new units are Apator Ultrimis and NEO ultrasonic meters. Ultrasonic measurement has no moving parts to wear out, so accuracy holds across a service life of up to sixteen years – and each meter carries both LoRaWAN and wM-Bus on board, leaving the choice of transport open building by building. Only a handful of hard-to-reach points need anything else.

100% coverage, by design

The tender set complete coverage as the baseline, not the aspiration. Divako designs, builds and operates the wireless network that ties the region together – LoRaWAN as the backbone, wM-Bus where it fits, and drive-by only for the rare location that still needs it. The point is an always-on connection that reaches deep basements and dispersed rural buildings alike.

That continuous link removes most of the need for manual or drive-by reading. For the municipalities it frees thousands of staff hours a year, and replaces a once-a-year snapshot with a live picture of the whole supply network.

One platform, any meter

Divako’s strength here is that it is meter-agnostic: it collects, decodes and harmonises readings regardless of the manufacturer underneath. That keeps both municipalities free of vendor lock-in and free to scale on their own terms in the years ahead. On top of the data sits alarm management – alerts for leaks and pipe bursts, backflow, dry or tampered meters, and frost risk – so problems surface the day they start, not at the next billing cycle.

Straight through to billing

Readings flow automatically from Divako into the municipalities’ own systems – Gemini and Komtek – for fully automated billing and analysis. Administration works from real-time data instead of estimates, residents pay for what they actually use, and abnormally high consumption that hints at a hidden leak gets flagged early rather than discovered on an invoice months later.

The bigger picture

Hamar and Ringsaker join a growing list of Norwegian municipalities reading their water networks remotely on Divako, alongside Oslo VAV and Asker Kommune. The pattern repeats: pick a multi-protocol, vendor-neutral platform, bring in whatever meter the procurement delivers, and turn raw sensor data into something the water utility can actually act on.
