Roundtable discussions: Table 3. The importance of a transcending plan (Delta plan) for water quality and availability in The Netherlands
Roundtable discussions: Table 3. The importance of a transcending plan (Delta plan) for water quality and availability in The Netherlands
Background
Both the availability and quality of water are increasingly under pressure in The Netherlands. The need to develop solutions is becoming apparent across all sectors of society, affecting both individuals, businesses, agriculture and nature. This raises questions about the long-term sustainability of the current water system and how we can achieve lasting, sustainable solutions. Especially since different aspects of water are governed by different bodies such as water boards, drinking water companies, and local-, regional-, and national governments.
Key take aways
• Control over water availability and the guarantee of water quality are not a given.
• Local initiatives and strategies need to be unified.
• Knowledge of technological solutions should be widely available and common practice.
• Water has evolved from being nearly free to a valuable resource.
• Education is essential in raising awareness about the need to secure water quality and availability.
• The current level of cooperation between water boards, governments, water companies, research institutions, and advocacy groups should be taken to a next level in order to increase the success rate of collective water management efforts.
• Long-term strategies should emphasize sustainable water use, proactive climate adaptation measures, and the protection of natural water resources.
• Public education, innovation in water management, and continuous stakeholder engagement will also play a crucial role in addressing future water challenges.
• It is not only the availability of water that raises concerns; the declining quality of water is equally alarming.
• stakeholders in the water sector should be advancing and promoting technological innovations, such as advanced water purification technologies. Sharing best practices and building collaborations across sectors is crucial for scaling up these technologies.
• More emphasis should be placed on creating systems that not only manage excess water but also store and repurpose it to combat droughts and water shortages.
Full story
The current water system is under increasing stress due to changing weather patterns, urbanization, and pollution. While there are established drainage infrastructures, the focus must shift to water retention and reuse. More emphasis should be placed on creating systems that not only manage excess water but also store and repurpose it to combat droughts and water shortages. A thorough evaluation of existing systems' adaptability to future conditions is needed. The impact has become particularly evident in recent years, as water companies have faced limitations in their primary supply, leading to reduced service levels. In some cases, water companies have even been unable to supply newly established businesses, such as NX Filtration.
It is not only the availability of water that raises concerns; the declining quality of water is equally alarming. While natural solutions and source-based pollution control should be prioritized wherever possible, purification technology will also play a critical role. Admittedly, this requires additional investment; however, failing to integrate advanced technology into our water management systems will not drive sustainability and will incur hidden costs, such as long-term health impacts. Accelerating progress will depend on faster technology adoption and the exchange of knowledge on these innovations. As contaminants increase, the resources and technologies required to ensure safe and clean water become more complex and costly, further complicating the ability to meet both environmental and public health standards. The costs involved to upgrade our water treatment facilities should not solely fall on general consumers but must be distributed more equitably. Heavy water users and significant polluters, particularly in industries, should bear a larger share of these costs through progressive pricing structures. This approach ensures that essential water consumption for individual households remains affordable, while those contributing most to water depletion or pollution are held accountable. By aligning pricing with environmental impact, we can drive more responsible usage and investment in sustainable practices without placing undue financial pressure on regular consumers.
To safeguard water quality and availability, a combination of regulatory frameworks, investments in infrastructure, and sustainable practices must be implemented. This includes improving water treatment facilities, promoting water-efficient technologies, enhancing groundwater management, and raising awareness about water conservation. Additionally, policies to reduce pollution and control industrial water use should be prioritized.
But the world of water is complex, and there are many different stakeholders responsible for drinking water, for waste water treatment, groundwater, surface water, nature, agriculture, city planning, or industry. The current level of cooperation between water boards, governments, water companies, research institutions, and advocacy groups should be taken to a next level in order to increase the success rate of collective water management efforts.
While there has been progress, obstacles include fragmented responsibilities, conflicting regulatory frameworks, and limited data sharing. Addressing these issues requires creating clear channels for collaboration, aligning goals across stakeholders, and fostering transparency and trust.
One of the key priorities for stakeholders in the water sector should be advancing and promoting technological innovations, such as advanced water purification technologies. These innovations must be made more accessible and seamlessly integrated into broader water management strategies.
Public-private partnerships and incentives for businesses to adopt water-saving technologies can accelerate the adoption of these solutions. Sharing best practices and building collaborations across sectors is crucial for scaling up these technologies.
Achieving a balance with water will require a cultural shift towards water stewardship, significant investments in water infrastructure, and stronger policy enforcement. Long-term strategies should emphasize sustainable water use, proactive climate adaptation measures, and the protection of natural water resources. Public education, innovation in water management, and continuous stakeholder engagement will also play a crucial role in addressing future water challenges.

Negative advice against eating fish from the Twente Canal, as advised by Rijkswaterstaat and the municipality of Hengelo
Rijkswaterstaat and the municipality of Hengelo advise, as a precaution, not to eat fish from the Twente Canal until further notice. This advice is due to the detection of elevated concentrations of HCH (Hexachlorocyclohexane) in the Twente Canal between Delden lock and Hengelo lock
Concentrations of HCH in the Twente Canal
Rijkswaterstaat and the municipality of Hengelo advise, as a precaution, not to eat fish from the Twente Canal. Elevated concentrations of HCH have been measured in the Twente Canal between Delden lock and Hengelo lock. HCH has been present in lower concentrations in the Twente Canal for some time due to known soil contamination. However, there is now a heightened concentration.
The contamination reaches the Twente Canal through groundwater. One of the known sources of contamination is the former AkzoNobel site in the municipality of Hengelo. HCH was produced during the manufacturing of Lindane, a pesticide produced between 1948 and 1952 in a former Stork factory. The Stork industrial site was taken over by AkzoNobel in 1954.
Water-related activities in the Twente Canal
Vitens, the regional drinking water company, does not extract surface water from the Twente Canal for drinking water purposes. Therefore, everyone in the region can continue to use clean and healthy drinking water. To maintain the water system during dry periods, the water boards Rijn and IJssel and Vechtstromen may draw water from the Twente Canal at certain locations.
Given recent rainfall and weather forecasts, it is expected that no water needs to be drawn in the coming weeks. Recreational water activities, such as rowing, can continue as usual. Swimming was and remains prohibited at the site.
Research and monitoring
HCH is relatively easily absorbed by fish and stored primarily in fish fat. Therefore, the concentration of HCH in fish is being investigated to determine when the negative advisory can be lifted.
Rijkswaterstaat and the municipality of Hengelo are investigating the cause of the increase and determining what measures can be taken to reduce the elevated concentrations.
Rijkswaterstaat and the municipality of Hengelo, along with the water boards Vechtstromen, Rijn and IJssel, and Vitens, are monitoring the concentration of HCH in the water and nearby streams. To monitor the level of contamination, Rijkswaterstaat has placed additional monitoring points in the Twente Canal and is now measuring the HCH concentration bi-weekly instead of monthly.
