NI Water aims to upgrade the ageing water mains system by renewing pipes and addressing problems such as bursts, poor pressure and leaks. Work is also necessary to improve water quality, to ensure sufficient capacity to meet future demands and to comply with all current National and European environmental regulations.

The current phase of the Water Mains Project will cost approximately £114million, which will be invested in laying approximately 905km of water mains right across Northern Ireland. Customers may experience a reduction in water pressure or an interruption to supply whilst work is being carried out. NI Water apologises for any inconvenience. Customers can call NI Water on 03457 44 00 88 for further updates.

Discoloured water can occur when the mains are disturbed. This can happen when there has been an interruption to supply following a burst main and the operational activity associated with the repair. The discolouration will be short-lived, and running the tap for a while should help clear it from the system.

All water is disinfected to ensure it is safe to drink. Following operational activity, the level of chlorine in the water supply may be boosted temporarily. The amount of chlorine is carefully controlled and monitored at our treatment works and strategic points in the distribution system.

Water quality samples are taken following burst mains repairs to ensure that a satisfactory water supply is restored to customers.
