Super Quality Measuring Sites

This project is a continuation on the work already done on the topic of “Super quality measuring sites” during the past years.

The work with testing new technology and bringing forth concepts for online monitoring of drinking water quality has now been taken one step further. This project seeks to, in time, be able to replace time-demanding analytical methods for microbiological quality monitoring with faster methods. Today it can take up to a week before quality can be determined.

In this project, VA SYD, Sydvatten, SWR, and NSVA collaborate to measure water quality with the help of online flow cytometry. During one year, summer 2022 to summer 2023, flow cytometrical data will be collected. This data will be correlated to other information collected from our utilities, such as hydraulic parameters, ordinary laboratory test data, as well as known events in the distribution network. This information is required to further approach an understanding for a concept for the solutions for online water quality monitoring of the future.

Several online flow cytometry devices are used to monitor bacterial concentrations in multiple sites in the drinking water distribution network. These sites will be evaluated to be able to answer the question where one should establish super quality measuring sites in the future. The expectation is that this data collection project will be yet another important piece of the puzzle in the process of establishing online monitoring of drinking water quality in a larger scale.

  • Understand how the quality of the drinking water varies over the year and seasons
  • Understand how online flow cytometry can help us monitor the quality of drinking water in near real-time
  • Develop further the concept for online monitoring of drinking water quality
