Minimizing Non-Revenue Water With MJK
Danish water supplier Birkerød Vandforsyning has since year 2000 been sectioning their grid. The sectioning has several purposes; to lower the risk of spreading pollution of the drinking water, to get a better and more detailed overview of consumption in the individual sections, and very importantly – to monitor the consumption - especially the night flow between 3-5 A.M.
By storing the data showing consumption in a section, you can map a graph for a given weekday. Jens-Ejnar Kristensen, Operating Manager in Birkerød Vandforsyning explains, ”The consumption varies from day to day, but over time, the individual weekdays are actually pretty comparable. Regarding level of consumption, Mondays look like Mondays and Saturdays look like Saturdays. If we have a leak in a section, we can see an overall increase in the section.”
Today, the grid is divided into 14 sections making the sections of such size that even a small leak is view-able on the graph.
For measurement, data logging and transfer, MJK delivered MagFlux and Mµ Connect. But also the fully mounted panels, and water detecting electrodes to secure the electronic parts in the well are delivered by MJK.
