NI Water to commence work in Henry Street area to reduce flood risk in Ballymoney
NI Water is to begin work in the Henry Street area of Ballymoney to improve the wastewater network and reduce the risk of out-of-sewer flooding during heavy rainfall.
The work – which will see the installation of dedicated stormwater infrastructure - forms part of NI Water’s stormwater separation programme, which removes rainwater from combined sewers that carry both wastewater and surface (storm) water.
Diverting rainwater into dedicated stormwater infrastructure helps free up capacity in the local sewerage system and reduces pressure on wastewater treatment works.
Approximately 190m of new stormwater pipe and seven new manholes will be installed, with work getting underway at the junction of Union Street and Meeting House Street on Monday, October 26.


Work will progress along Ozone Avenue and Henry Street as far as No. 3 Henry Street, over a period of approximately eight weeks.
To protect the public and construction team, a one-way closure will operate in each working area as pipelaying progresses. Access to homes and businesses will be maintained via a one-way system throughout the works.
Robert McLean, NI Water Senior Project Manager said: “The work in Ballymoney forms part of a wider NI Water investment to modernise wastewater infrastructure in areas facing network constraints, creating additional capacity to support sustainable development while improving resilience for local communities during periods of heavy rainfall.
“Our contractor, Civco, will strive to minimise disruption and complete the work in the shortest possible timeframe. NI Water and our project team from AtkinsRéalis and CivCo thank residents, businesses and road users for their patience and cooperation while we complete these essential improvements.”
