Paying the sewage charge

You pay a sewage charge (rioolheffing) for your wastewater and for rainwater that ends up in the sewer. The sewage charge is part of the municipal taxes and is collected by the municipality, which uses that money to pay for maintenance and replacement of the sewers. Some municipalities also call the sewage charge sewage tax (rioolbelasting).

Each municipality has its own way of calculating the sewage charge. For example, some municipalities calculate the sewage charge based on the value of the property. Others base it on drinking-water consumption. To find out how your municipality calculates the sewage charge, contact your municipality. 

The sewage charge is included in the municipal tax bill. This is usually sent out in the first 2 weeks of February.

Paying the sewage charge

When determining the sewerage charge, the municipality distinguishes between a user and the owner of the property. The sewerage charge therefore consists of an owner's part and a user's part.

There are 2 sewerage rates. Every owner or user of a piece of land pays sewerage and water management charges each year. This ensures the construction, maintenance, and replacement of the sewer system. We also ensure the processing of wastewater, rainwater, and groundwater. Therefore, you also pay sewerage and water management charges if your piece of land is not connected to the sewer system.

You only need to pay sewerage charges if you live in the Netherlands and are registered with a municipality.

The following rates apply:
