Current legislation

The Water and Sewerage Services Act (Northern Ireland) 2016 

The Water and Sewerage Services Act (Northern Ireland) 2016 received Royal Assent and came into operation on 23 March 2016. Sections 4, 5 and 6 of the Act relating to Sustainable Drainage Systems, Refusal of Surface Water Connections and Adoption Agreements will come into operation two months after the Act received Royal Assent, on 23 May 2016.  The purpose of the two month delay is to facilitate the issue of information and guidance to stakeholders, in particular, developers.

NI Water officials have been working closely with DfI regarding advice and guidance on the changes effected by the Act and will continue to work with stakeholders over the coming months.
