Mining levy areas located in the Boom aquitard (code 0300), the Bartoon aquitard (code 0500), the Paniselian aquitard (0700) and the Ieperian aquitard system (code 0900) (tax year 2009-2017)

The levy should encourage groundwater consumers to use groundwater sparingly. It also wants to encourage the use of more sustainable alternatives, such as the use of rainwater. The amounts received will be transferred in full to the MINA Fund. The charging policy is based on the principle of the low and territorial factors. These factors are incorporated into the charging formula. The low factor relates to a main hydrogeological unit (HCOV code) and is used for layers that require a tightened charging policy as a whole. With the area factor, a layer locally can be applied a differentiation in the levy.
