Water utilities use District Metering Analysis (DMA) as a fundamental tool for monitoring and managing water distribution networks. DMA involves dividing the network into smaller districts or zones and installing flow meters to measure the flow of water into and out of each zone. By analysing flow data from DMA, utilities can identify leaks, assess water consumption patterns and make informed decisions about infrastructure improvements and resource allocation.
Use Cases about:
The Norwegian municipality of Lillestrøm has 87,500 residents and is located at the confluence of three rivers (Glomma, Nitelva, and Leira) creating the largest inland delta in Northern Europe, surrounded by the nature reserve Øyeren.
To the environmental engineers at Lillestrøm municipality, water presents both a wealth of recreation opportunities and a challenge to protect waterways, manage wastewater, and keep the inhabitants, human and wildlife, safe from the effects of flooding.
InfoTiles District Metering Analysis (DMA) provides monitoring of pressure zones and supply zones in the water supply grid, in real time.
If a water utility has leaking wastewater pipes, it can result in rainfall infiltrating the wastewater grid. This can overload the wastewater system during periods of heavy rain or storm events, leading to the release of untreated wastewater into the environment. It also increases the risk of cross-contamination of drinking water – though this is rare.
The collection of data across many sources gives Lillestrøm municipality unique insight into various environmental challenges. Now they are well equipped to handle rising sea levels, torrential rain and floods in a resource-efficient way.
In the last 10 years damage caused by weather and natural events has cost 27 billion kr in Norway. Some of these damages could be prevented with a warning system and swift action from the municipalities. The Norwegian Water Resources and Energy Directorate (NVE ) do have flood warnings, but only for larger rivers.
