Environmental guidance for your business in Northern Ireland & Scotland


Making connections to sewers or surface water drains

What you must do

Make sure that you know the locations of all existing foul and surface water drains and sewers, and where they lead. If possible get a drainage plan of the site where you are working.

When connecting a discharge to a drain or sewer, always check that you are connecting to the correct system.

Never make any discharge to a drain without prior authorisation.

Materials for recycling, such as copper piping are likely to be waste and, if so, will be subject to the requirements of the waste management and duty of care regimes.
