NI Water Crisis: Underinvestment Threatens Water Supply
26 Nov, 2025
Summary
- Northern Ireland risks insufficient drinking water during hot weather.
- Wastewater pollution risks turning Belfast Lough into the 'next Lough Neagh'.
- NI Water needs almost double current investment to reverse underfunding.
Northern Ireland is at risk of insufficient drinking water during periods of hot weather due to chronic underinvestment in its water infrastructure. NI Water's chief executive stated that the company requires nearly double its current capital investment to begin rectifying years of neglect. This shortfall also impacts housing and economic development, with applications for wastewater connections currently halted.
The strained wastewater system is a major concern, with pollution incidents becoming inevitable as existing connections exceed network capacity. This situation poses a significant environmental threat, with Belfast Lough potentially becoming "the next Lough Neagh" due to sewage pollution. Past reports have highlighted how insufficient water infrastructure hinders development.
Urgent action and substantial investment are deemed critical to avert these crises. NI Water aims for a future free from prosecution for pollution, but this aspiration requires not only financial input but also collective action. Regulatory bodies are now investigating the management of sewage discharges into Belfast Lough.
