With the successful go‑live of the HR processes earlier this year, we have now fully transitioned to SAP S/4HANA. This is SAP’s latest ERP software, and it supports us in further developing our digital environment.

An action programme was launched by the Interprovincial Consultation (IPO), Vewin and the Ministry of Infrastructure and Water Management (IenW) in 2025. The report sets out the actions being taken at both local and national level to ensure the availability and usability of drinking‑water sources through to 2030.

Large groups of girls from two different secondary schools visited Vitens to learn about the technical sector. They were given a glimpse into how varied and important the field is, with a particular focus on the world of drinking water. It was a day full of discoveries, inspiration and practical experience.

A couple from Burgum received an exceptionally high annual bill from Vitens. They involved the TV programme Radar because there was a dispute over whether the drinking water had actually been consumed by the customer. Independent investigation did not identify a clear cause. Vitens engaged with the customer and resolved the issue to the couple's satisfaction.

Vitens' production site in Doorn closed because the facility was outdated and the source had become increasingly vulnerable to contamination. Residents who previously received their drinking water from this site have, since May 2025, been supplied from the Cothen production facility.

Vitens received several damage reports as a result of the storm. There were many fallen trees and around ten leaks in the Achterhoek. A great deal of effort went into repairing the damage as quickly as possible.

The Ministry of Infrastructure and Water Management launched a campaign calling on people to stop taking drinking water for granted and to recognise it as something we must look after together. Vitens played an active role in this campaign. There were four water challenges: preventing water shortages, reducing flooding, preparing for extreme weather events, and improving water quality.

This is a day dedicated to tap water as a healthy thirst quencher and to increasing water awareness. Some 230,000 children participated nationwide. National Tap Water Day 2025 was launched in Leeuwarden. Mayor Buma, research institute Wetsus and Vitens CEO Tjeerd Roozendaal were also present.

The agricultural consortium ReGeNL and Vitens are joining forces to promote future-proof farming and clean drinking water. This collaboration encourages farming practices that promote healthy soil, adequate water supplies and clean groundwater, without prescribing how these goals should be achieved.

An Enterococcus bacterium was detected in the drinking water, prompting Vitens to issue a boil water advisory for around 125,000 households in parts of Utrecht and surrounding areas. This had an impact on residents, led to a rush for bottled water and attracted significant media attention. Following two clean tests, the boil water advisory was lifted on 4 November.

In 2025, Vitens organised the annual European Benchmark Cooperation (EBC). EBC offers benchmarking and improvement programmes for water and wastewater companies. It helps companies improve their (drinking) water services. There were over 90 participants from 16 countries. The meeting focused on sharing knowledge, strengthening collaboration, and discussing new insights on investing in resilience.

Completion of the expansion of water abstraction capacity at Boerhaar/Diepenveen. Overijssel has almost no remaining reserve capacity for drinking water. To increase reserve capacity, we upgraded the production site in Diepenveen and installed new abstraction wells in Boerhaar. As a result of this investment, we have 1.15 million cubic metres per year of additional production capacity. We also made the treatment process more sustainable. In early 2026, the final steps will be taken to enable actual supply to the distribution network.

On Boxing Day, a water‑main break occurred near the De Folgeren water tower in Drachten As a result, a large part of Drachten and the surrounding villages experienced water outages or reduced pressure (around 50,000 household connections). Our colleagues were quickly on site and worked with the parties involved to ensure a safe and swift resolution. Because it involved a main line, the repair required additional time and caution, but fortunately the disruption was resolved the same day. The water supply disruption led to a surge in demand for bottled water.
