NI Water Crisis: Underinvestment Threatens Water Supply

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.
