DAERA Minister Andrew Muir has proposed ending a 2007 arrangement that limits enforcement against Northern Ireland Water. The plan would place the utility under the same regulatory rules as farmers and industry. The Northern Ireland Environment Agency would withdraw from the Statement of Regulatory Principles and Intent with NI Water.

The move addresses ongoing water pollution issues, including more than 20 million tonnes of untreated sewage and wastewater discharged annually into Northern Ireland waterways. Only 29 percent of surface water bodies currently meet good ecological status. Minister Muir stated the change aims for fair regulation across sectors to protect public health and the economy.

Ulster Farmers Union Deputy President John McLenaghan challenged NI Water's claim that agriculture causes 70 percent of pollution entering Lough Neagh. He described the figure as based on modelling with uncertainty and questioned data reliability. The union contacted NI Water to request a retraction and apology.

McLenaghan noted farmers have followed regulations on nutrient management and storage for 20 years while reporting suspected raw sewage discharges. The union accepts agriculture's role in water quality but calls for shared accountability.

Additional measures include a Fisheries and Water Environment Bill set for May 2026 to update enforcement powers and raise maximum pollution fines to £50,000. Belfast Lough's shellfish area faces designation as sensitive, requiring better wastewater treatment. A review of discharge consents is also underway.
