NI Water will continue our wastewater network improvements in Castlewellan, County Down in the new year.

Pipelaying is due to commence on Mill Hill, Castlewellan on Monday 5th January 2026 opposite St. Paul's Church.

A lane closure with traffic lights will be in place on the Castlewellan-bound lane around the working area.

Pipelaying will continue up Mill Hill as far as Clarmont Avenue and motorists may need to allow extra time for their journeys while this work is ongoing.

NI Water and our contractor BSG Civil Engineering thank the public for their ongoing patience and cooperation as we upgrade the wastewater network in Castlewellan. Signage will be in place and every effort will be made to minimise disruption and complete each section of work as quickly as possible.
