Belfast Lough’s Dirty Secret: How Planning Failures Are Flushing Our Future Away
Northern Ireland’s waterways are drowning in a crisis. From the River Lagan to Belfast Lough, raw sewage and toxic pollution are choking ecosystems once celebrated for their natural beauty. The culprits? Overburdened sewage systems, relentless housing developments, and a government asleep at the wheel.
Across the system untreated sewage is routinely pumped into waterways like the River Lagan, flowing straight into Belfast Lough—a site of global importance for biodiversity.
Despite this, despite our highlighting to planners and showing papers from NI Water itself, as a microcosm of this scandal, is the Drumbeg Wastewater Treatment Works (WwTW).
In October 2024 officials approved yet another planning application—LA05/2022/0033/F—without fully disclosing the catastrophic environmental impact it could have.
The Truth They Didn’t Tell You
During a planning meeting on 18 September 2024, an official calmly stated:
“No European or Ramsar site of international importance are identified within the application site.”
While technically true, this carefully worded statement ignored the bigger picture. Wastewater from the proposed development will be funneled into the overworked Drumbeg WwTW, already struggling to handle the load. From there, the pollution flows into Belfast Lough, a Special Protection Area (SPA), Area of Special Scientific Interest (ASSI), and Ramsar Site of international importance.
It’s a scandal hiding in plain sight, and our rivers and seas are paying the price. This same scenario is happening across the Lagan Valley and the country.
Overflowing with Neglect
The sewage system isn’t just broken—it’s a public health and environmental disaster. According to the Office of Environmental Protection (OEP), 69% of Northern Ireland’s waterways fail to meet basic ecological standards.1 A report by the Living With Water Programme revealed that untreated sewage regularly spills into Belfast Lough due to overflows during even light rainfall.2
It gets worse. The BBC’s hard-hitting Spotlight investigation, “The Sewage Scandal”, aired on 3 December 2024, exposed NI Water as “Northern Ireland’s biggest polluter.” The show revealed that 30% of wastewater never even reaches treatment plants. Instead, raw sewage—yes, largely human waste— is dumped unaltered straight into our rivers and the sea.3
Paddy Brow from NI Water admitted on the programme that the system is so overwhelmed they have “no choice” but to release untreated waste into Belfast Lough. This isn’t just a failing system—it’s a ticking time bomb.
The Price of Inaction
The Northern Ireland Audit Office’s report, Water Quality in Northern Ireland’s Lakes and Rivers, issued a grim warning:
“European targets for improving water quality in Northern Ireland’s rivers and lakes by 2027 will not be met. As of 2021, less than one-third of rivers had good ecological status. For lakes, the figure was just 14%.”4
Yet, planning officials continue approving new housing developments, pushing already failing sewage systems to the brink. The cumulative impact of these decisions? Polluted waterways, collapsing ecosystems, and a bleak future for Belfast Lough.
Belfast Lough: From Sanctuary to Sewer
Belfast Lough is an ecological treasure under siege. Its designation as a Ramsar site should have guaranteed its protection. Instead, it’s being sacrificed for short-term gains. Pollution from homes, streets, and farms all end up here, and with untreated sewage added to the mix, the situation has become a full-blown crisis.
The River Lagan—once a lifeline for wildlife—has become a conveyor belt for pollution, carrying waste from our homes directly into this fragile marine habitat.
The Fight for Clean Water Starts Now
Belfast Lough’s story is a wake-up call. It’s time to take action:
- Stop approving new developments until the sewage system can handle the load.
- Force NI Water to fix its crumbling infrastructure. No more excuses, no more pollution start with real honest measurement of output.
- Demand accountability from planners who downplay environmental risks.
This crisis isn’t going away on its own. Every time we flush the toilet or let the rain wash pollutants into the drains, we’re adding to a problem that’s drowning our future. It’s time to clean up our act before Belfast Lough — and everything it sustains including some of us — are lost forever.
