Sewer Connection Permit

A sewer connection permit (rioolaansluitingsvergunning) is required when you want to connect a building to the municipal sewer system or modify an existing sewer connection. This applies to new construction, renovations that change drainage layouts, and temporary connections for construction sites or events.

You apply for this permit at the municipality where the property is located, usually through an online portal. The municipality assesses whether the connection meets technical standards and fits within the local sewer plan. Conditions may cover pipe diameter, connection point location, and separation of rainwater and wastewater. A licensed contractor must carry out the physical connection work.
