Information – about the parallels

The programme will give a variety of possibilities for knowledge sha­ring and interaction. The conference is organised with conference sessions, poster presentations and workshops.

Conference sessions

The main venue for presentations which will bring you up to date on the latest knowledge in the Nordic water sector.

Workshop sessions presentations and dialogue in groups:

The aim of the workshops is to address issues and topics which need to be discussed in depth, in combination with sharing knowledge and experience from the different countries.

Each workshop is 90 minutes and starts with a number of presentations. The presentations provide information addressing the topic of the workshop. Some are picked from the submitted abstracts, others are invited speaker. The length of the presentation is decided by the organizer of the workshop, but would typical be 10 minutes.

After the presentation, there will be group discussion or plenary discussions. The details of the workshop will be further elaborated by the representative from the programme committee who is organizing the workshop.

Poster sessions:

The poster sessions are organized thematically. Each poster session is 90 minutes. Three to five presenters (depending on the session) are given 10 minutes each to present their work (poster) from the podium in the poster room. For posters not selected for oral presentation title and author will be presented on a slide by the session chair in the beginning of each session. The authors of all the posters (with and without presentations) in the session will be standing by the poster ready for interested participants to elaborate further after the presentations.

13:00–14:30 Workshop 7 – When operations fail in the distribution system

This workshop will give an overview of common practice and routines in the Nordic countries following an incidence in the distribution system, planned or unplanned, which can be a threat to human health. Is boil water advisory compulsory and/or is chlorination always a part of the routine after repair? And do the consumers follow the advices given? What can we learn from each other, and should there be a common practice in the Nordic countries? This is some of the questions which will be discussed in this workshop.

The following subjects will be presented during this workshop:

  • Practice in the Nordic countries, Vidar Lund,Norwegian Institute of Public Health
  • Drinking water and risk perception – a study on boil water advisories and behaviour in the municipality of Bærum, Susanne Hyllestad, Norwegian Institute of Public Health

15:00–16:30 Event – Young Water Professionals

There are different degrees of organization of young water professionals in the Nordic countries. Some countries have come a long way in organizing young water professionals in their country and are very active, while others have just begun. At the same time, we know that the young people’s voice in the international water sector is crucial to address the challenges facing the international water sector. Therefore, it is important for young people in the water sector to learn from each other across borders and collaborate on matters that are natural to solve jointly.

On June 12, we gather all the young participants at NDWC to talk about the challenges young people see in the water sector in their country, and to discuss how we can strengthen the international cooperation among young water professionals between the Nordic countries.

We will also try to come up with some specific issues on which we can cooperate in the years to come. Maybe it is possible to collaborate on a joint event at the IWA World Water Congress & Exhibition in Copenhagen 2020? We will see!

Omar Samy Gamal from Norwegian Water, and Marie Rødsten from Young water Professionals in Norway (VA-yngre) will guide us through the workshop.

This event will be administrated by Omar Samy Gamal from Norwegian Water

08:30–10:00 Workshop 9 – Materials in contact with drinking water

Materials in contact with drinking water is increasingly important, as it is clear that contamination of the water system doesn’t have to be outside treats. It is also important what products and materials you use. It is becoming a bigger issue by the minute, in all countries where the regulation is formulated on the basis of the EU drinking water directive. The ongoing revision of the DWD has changes in the setup that makes it even more important to have insight in this very complex matter.

How do we ensure that the products and materials on the market is safe ?

There is a lot of components to choose from, but what are reasonable claims towards the producers?

How do we ensure an efficient scheme that keeps the water wholesome, clean and safe for the consumers without the product price escalates ?

There are different approaches across the Nordic countries, and also different roles and responsibilities for the utilities. At the workshop you will get an introduction to the different approaches, and have the opportunity to discuss pros and cons with other water professionals from the Nordic countries.

The main topic of this session is  the Implementation of the renewed annex II (commission directive (EU) 2015/1787) of the Drinking Water Directive in the Nordic countries, focusing on the requirements and experiences on the risk assessment based compliance monitoring (Annex II, Part C) and  sampling without prior flushing (Annex II, Part D).

Authorities from the Nordic countries will attend the workshop. From The Norwegian Food safety authority, Line Ruden, Finnish National Supervisory Authority for Welfare and Health, Jaana Kilponen, Icelandic Food And Veterinary Authority, Sigrún Ólafsdóttir and the Swedish National Food Agency, Department of Control Support Agneta Tollin.

Questions that will be presented and discussed in the workshop:

  • How is risk assessment based compliance monitoring adapted? Possible or compulsory? What requirements are set for the risk assessment? What is the approval process for the risk assessment? How are the results of the risk assessment informed? How is the monitoring based on the Water Framework Directive taken into consideration?
  • How were the compliance monitoring samples taken for different parameters before? How are the compliance monitoring samples taken now? What is the reasoning for the present sampling method? Has the new method affected the number of non-compliances?
  • How are water users advised to use tap water for drinking and food?
