Flemish Water Bills Break 500 Euros as Minister Objects

The average water bill for a Flemish household has surpassed 500 euros a year for the first time, according to the region’s utilities regulator, as a plan to push charges even higher has triggered a public split within the Flemish government.

A typical household of 2.3 people saw its annual water bill rise from 489 euros in 2025 to 507 euros this year, the Vlaamse Nutsregulator (VNR) reported. Larger families face steeper costs: an average four-person household pays 716 euros, while a five-person household pays 836 euros.

A Steep, Long-Term Climb

The increase caps years of steady rises driven largely by the cost of water purification and sewer management. As VRT NWS detailed, the average Flemish bill stood at 352 euros in 2020 and 410 euros in 2023 before climbing to 489 euros in 2025. An average household consumes roughly 70 cubic metres of water a year. The VNR, which took on its role as watchdog for the water sector on 1 January 2026, said it would rule on next year’s tariffs in the coming months.

A Budget Fight in the Open

The milestone coincides with a politically charged dispute. News leaked on Thursday that an increase in the water bill sits on the table in the Flemish budget negotiations, potentially adding 40 to 60 euros per household per year and raising 80 million euros or more for the regional treasury.

Environment Minister Jo Brouns (CD&V), whose portfolio covers the water bill, came out firmly against the idea. “People are already afraid to go to the gas station, gas prices are historically high, the shopping cart is getting more expensive,” he told VRT NWS De Ochtend. “Then taxing families with a higher water bill, which has recently already been increased, that cannot be for me.”

Brouns argued the move would breach an existing agreement. “We approved a drinking water plan with this government, which includes a tariff plan… We are not now going to commit contract breach to raise that price again. That was not agreed.” He suggested savings could instead be found by making the Flemish government itself “leaner and more efficient.”

Depraetere Leaves the Door Open

His coalition colleague Melissa Depraetere (Vooruit), the Flemish Vice-Minister-President, struck a more cautious tone. “We still have a whole weekend to make the budget proposal better and fairer,” she said before the weekly ministerial council. “There is still a lot of work. N-VA has put a proposal on the table. That will not be the proposal we end up with.”

Depraetere acknowledged the measure touches directly on purchasing power, an area her party has championed, but declined to issue a hard veto in the press. She said the government should also weigh higher registration duties for homes over 500,000 euros, cuts to business subsidies, and closing loopholes in inheritance and gift taxes.

Wider Budget Pressure

The water bill fight plays out against a broader fiscal squeeze. Flanders is seeking 1.5 to 2 billion euros to balance its budget, with an agreement needed by Monday, 28 September, when Minister-President Matthias Diependaele (N-VA) delivers his September Declaration in parliament.

At the federal level, Prime Minister Bart De Wever’s coalition is searching for roughly 10 billion euros to avoid a debt spiral, with a deadline to submit its budget to the European Commission by 15 October. The parallelism has made every potential revenue measure politically fraught.

The political sensitivity is not new. As far back as November 2024, Groen faction leader Mieke Schauvliege warned that the government “has only one solution every time: raising the bill for households. That must stop.” She called for the burden to be shared proportionally, arguing that “households cannot pay all the extra costs while industry stays out of the firing line.”

What to Watch

The immediate question is whether the water bill increase survives the weekend’s negotiations or is dropped, as CD&V successfully defended a low water bill in a similar standoff last year. The VNR is also due to rule on 2027 tariffs, which could add further pressure. For Flemish households, the direction of travel — upward — appears unlikely to reverse soon, regardless of which side prevails in the cabinet room.
