Legislation – finance


According to environmental legislation, a landowner is obliged to connect to the public drainage system once the municipality has run the service pipe to the land. In existing systems it is normal for both rainwater and wastewater to be connected to the municipality's drainage system.

In new development areas it has become increasingly common that roof water must seep onto the property’s own land, while wastewater and rainwater from roads are drained into the municipality’s drainage system.

You will always need authorisation from the municipality if you want your roof water to be seeped down. The municipality can either simply give a seepage permit or they can choose to authorise the landowner to withdraw from the community sewer system and possibly receive a refund of the connection charge for rainwater.


In Executive Order No. 501 of 21 June 1999 on wastewater permits, etc., under chapters 3 and 4 of the Danish Environmental Protection Act as amended on 7 June 2000 (Executive Order No. 693), rules have been laid down for how the landowner can withdraw from the community sewer system.

The conditions for a complete or partial withdrawal from the community sewer system are:

  • In the wastewater plan, the area must be indicated as an area where the municipal council is prepared to completely or partially cancel the connection obligation.
  • The withdrawal must have been agreed between the landowner and the municipality.
  • The sewer supplier’s total finances must not be significantly adversely affected.
  • The sewer supplier must be able to carry on working technically soundly.
  • Authorisation for an alternative removal/drainage of the wastewater must be possible.

For authorisation to withdraw from the sewer supplier the municipality is not obliged to make a reimbursement, since the sewer supplier has already paid the construction costs which the connection charge is meant to cover.

The municipality can, however, choose to offer the property owner a complete or partial reimbursement of the connection charges. The standard connection charge was implemented by Act No. 325 of 14 May 1997 to amend the Danish Environmental Protection Act and the Act on payment regulations for wastewater treatment plans, etc., which entered into force on 1 July 1997. The indexation of the connection costs is thus calculated from this date.

A possible reimbursement will always be subject to an alternative system for removing wastewater being set up and the payment being made with proof that the alternative removal has been installed. It is up to the municipality which documentation must be presented. The municipality's offer of reimbursing connection charges is normally subject to a time limit.
