Faster methods of analysing microbiological quality of drinking water after pipe breaks or new pipe installations could have beneficial implications. In this article, a summary is presented of the findings in a recent master thesis about how flow cytometry and cultivation-based techniques can be used to monitor water quality in connection to maintenance works, and […]

Using open-access data sets on water and soil from Swedish authorities and compiling them in a QGIS-programme made it possible to present and visualise the water budget of the Lagan River Catchment. Based on the estimations of the water volume in groundwater reservoirs and lakes the total maximum available volume in the Lagan River Catchment […]

The article analyzes the observations of the impact of preserved landfills on the hydrosphere (ground-, surface water, and filtrate) of adjacent territories in the countries of Northern Europe and the Russian Federation. The behaviour of more than 80 components over a long time was analyzed. Graphs of changes in the most representative of them are […]

UV-LED technology is a modern method to safeguard drinking water by disinfecting water with UV-pho-tons generated in a light emitting diode (LED). The technology has received increasingly higher attention due to its capacity to generate UV-light without use of mercury with a number of additional benefits compared to traditional UV-lamps. UV-LED’s are fast, operated digitally, […]

This work kick-starts AI (artificial intelligence) for pipe management among Swedish water utilities. The current work with pipe management is mainly reactive; leaks are repaired after they are detected, sometimes with large costs if the leakage is extensive and critical. With this article, we want to focus on proactive pipe network management and discuss risk […]
