The Water Police Service is part of the National Unit of the Dutch police.

It stems from the former State Police in Water. The service was covered by the KLPD from 1993 to 2013.

In 2013, the Water Police Service, together with the Railway Police Service (DSP), the Traffic Police Service (DVP) and the Aviation Police Service (DLVP), became part of the Infrastructure Service (DINFRA) of the National Unit of the Dutch police. [1]

The Water Police Service is responsible for the detection, supervision and enforcement of the main transport axes, main waterways and large water surfaces in the Netherlands. [2]

In the port of Rotterdam, the same duties are performed by the Seaport Police, part of the Rotterdam Regional Unit.

Part of the water surveillance is carried out by personnel from the regional units.
This also happened before the introduction of the National Police. As a result, the purchase of boats was very fragmented and there was a wide variety of small boats for inland waterway surveillance. The fleet has been standardized since the arrival of the National Police.
