We are used to thinking that tap water in Norway is safe, but experts in the field are concerned and there have been several outbreaks of harmful bacteria. The challenges are first and foremost old and poor wiring, which entails the risk of large leaks and intake of foreign elements. Today’s poor water supply network also entails an increased risk of unhealthy bakeries in the water, something i.a. Anders Bekkelund, senior adviser at the Norwegian Food Safety Authority, points out in the online newspaper of Teknisk Ukeblad (TU) https://www.xn--nringslivnorge-0ib.no/vart-vann/betydelige-utfordringer-for-leveranser-av-drikkevann/#

Rådgivende Ingeniørers Forening (RIF) writes in the report «Norway’s condition 2019 water supply and drainage system» https://www.rif.no/wp-content/uploads/2019/08/Vann-Avl %C3% B8psanlegg.pdf that with the current replacement rate, it can take 150 years before water supply lines in Norway are properly replaced.

In recent years, there has been an increasing amount of organic material (humus) in drinking water. This is observed i.a. through an increase in so-called color numbers. Pure water is colorless, while humus gives a yellow-brown hue. In addition to the fact that an increased amount of humus in the water is undesirable in itself, an increased amount of humus also entails an increased risk of harmful bacteria in the water to households because the purification technology used in the waterworks (UV filter) does not work properly at high color levels. It is shown in the attached report. https://detallerbestevann.com/forskning/

DabV is a revolutionary technology based on galvanic elements that has been shown to eliminate harmful bacteria even at high color levels on the water. https://detallerbestevann.com/forskning/ DabV can be easily mounted by placing the unit next to the pipeline that enters the household. In this way, the individual can prevent unwanted bacteria in all the water used in the household.

In recent years, water sources have shown an increased degree of NOM (color number).

At the same time, there is an increasing focus on micro-contamination (including drug residues / small bacteria) that can pass purification steps. These conditions trigger a great need for upgrading the waterworks.

  • Clean water is essential for people’s health. We must therefore ensure that we have good alternatives if a situation arises so that it is necessary to supply water from alternative sources.
  • More research should be done on the extent of waterborne infection to people’s health and the risk that infection may occur. Other risks must also be focused on when the management and monitoring of the facilities is increasingly digitized.
