Clarification of Rules for the Discharge of Domestic Wastewater
We are working on clearer and more enforceable rules for the existing ban on the discharge of domestic wastewater by businesses and group accommodations. Preparations for implementing the discharge ban have revealed that certain aspects of the current regulations are insufficiently clear and enforceable in practice. We are therefore examining how the rules can be clarified and improved without compromising the goal of protecting and improving water quality. For existing situations subject to the discharge ban, this means that HHNK will not conduct active “ supervision ” in 2027. However, HHNK will continue to conduct “ supervision ” in response to indications of acute risks to water quality.
HHNK is working to improve the rules
A discharge ban applies to businesses and group accommodations into small ditches and waterways in order to further improve and protect water quality. During preparations for implementation, it became apparent that applying the current rules in practice is more complex than previously thought. In particular, the application of the so-called pollution value of 6 population equivalents (PE) presents practical challenges. HHNK is therefore investigating how the regulations can be clarified and improved. In addition, HHNK is examining whether the rules can allow for tailored solutions in appropriate situations. The fundamental principle remains unchanged: protecting and improving water quality in small water bodies.
Implementation of the " supervision " and Enforcement in 2027
Because the current regulations are being amended, the priority for supervision and enforcement will shift to other activities in 2027. Jos Beemsterboer, portfolio holder for integrated water management:“Cleanand healthy water is what we strive for every day. The rules must be clear and enforceable. Stakeholders must be given sufficient time to take appropriate measures. That is what we will be focusing on in the coming period.”
This does not mean that enforcement will cease entirely. The current rules remain in effect, and HHNK will continue to take action in response to indications of acute risks to water quality. Each discharger is still responsible for determining which rules apply to their specific situation.
Working Together for Clean Water and a Feasible Approach
The discharge ban took effect on January 1, 2024, as part of the Water Board Regulation. The ban applies to commercial discharges of domestic wastewater and discharges from group accommodations into small ditches and waterways when the pollution level is 6 IE or higher. The purpose of the ban is to protect and improve water quality in smaller water bodies.
The ban was prompted by research showing that existing treatment facilities for larger wastewater flows often do not function adequately. As a result, contaminated wastewater can enter surface waters, leading to a deterioration in water quality and conflicting with the goals for clean and healthy water.
To achieve this objective in practice, HHNK is working with municipalities to identify which businesses and other locations may be subject to the discharge ban. This assessment is still ongoing. The most appropriate solutions are being explored on a case-by-case basis. HHNK is involving municipalities, business owners, and other stakeholders in the preparation of the amended regulations. HHNK will incorporate the results into a proposal to amend the Water Board Regulation, which is expected to take effect on January 1, 2028.
