Minimizing Non-Revenue Water With MJK
Danish water supplier Birkerød Vandforsyning have since year 2000 been sectioning their grid. The sectioning have several purposes; lower the risk of spreading a pollution of the drinking water, get a better and more detailed overview of the consumption in the individual sections, and very important – to monitor the consumption, 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 week days actually are pretty comparable, Mondays look like Mondays and Saturdays looks like Saturdays on the level of consumption. If we get a leak in a section, we can see an overall increase in the section.”
Today the grid is divided into 14 sections that make the sections of such size that even a small leak is viewable on the graph.
MJK delivered MagFlux and Mµ Connect for measurement, data logging and transfer, but also the fully mounted panels, and water detecting electrodes to secure the electronic parts in the well are delivered by MJK.
