Northern Ireland's Massive Illegal Dump Could Finally See Clean-Up Begin in 2028

One of Europe's Biggest Illegal Landfills Inches Toward a Long-Awaited Clean-Up

Northern Ireland's Environment Minister Andrew Muir has confirmed that remediation work at the notorious Mobuoy illegal dump site could get underway in 2028, with the full clean-up potentially taking as long as five years to finish. The announcement marks a significant — if slow-moving — step toward resolving one of the most serious environmental scandals in the region's history.

What Is the Mobuoy Site?

Located at Campsie in County Londonderry, the Mobuoy dump was uncovered in 2013 and quickly gained notoriety as one of the largest illegal landfill sites anywhere in Europe. Spanning more than 100 acres — roughly equivalent to 65 to 70 football pitches — the site holds an estimated 1.6 million tonnes of waste in total, of which approximately 627,000 tonnes are believed to have been disposed of illegally.

While some of the buried rubbish dates as far back as the 1960s, the illegal dumping activity was directly tied to two businessmen who were sentenced to prison in June of last year. Paul Doherty, from Culmore Road, admitted seven charges related to illegal waste disposal carried out between 2007 and 2013, receiving a one-year custodial sentence. His co-defendant Gerard Farmer, from Westlake in Derry, pleaded guilty to three charges spanning 2011 to 2013 and was handed a 21-month prison term. The presiding judge at Londonderry Crown Court noted that both men had acted with clear intent and were driven entirely by financial profit.

The Road to Remediation

Speaking on BBC Radio Foyle's North West Today programme, Minister Muir described the clean-up as "non-negotiable," emphasising that the people living in the surrounding area "deserve" to see the site properly restored.

His department is currently working toward finalising a cost estimate for the remediation — a process he expects to take up to three months. Once that figure is established, the next steps will include adopting a formal remediation strategy, preparing a business case, and securing the necessary funding, which could take a further five months. Contractor procurement is anticipated to begin around April 2027, a stage that itself may require nine to twelve months to complete.

Given the scale and complexity of the contamination, Muir acknowledged that the large-scale clean-up works will require financial backing from the UK government.

How Much Will It Cost?

The financial scope of the project is substantial. Figures published in February 2024, drawn from the 2022/23 accounts of the Department of Agriculture, Environment and Rural Affairs (Daera), initially placed the cost anywhere between £17 million and £700 million. However, the upper end of that range would only apply if all waste were physically excavated and transported off-site — an approach that is not currently being pursued.

The most up-to-date working estimate stands at approximately £107 million, based on implementing a range of targeted pollution prevention and containment measures. Importantly, this figure is considered a snapshot in time and is expected to increase the longer it takes to finalise and act on the remediation plan.

Local Politicians Express Frustration

Not everyone is satisfied with the pace of progress. SDLP Member of the Legislative Assembly Mark H Durkan, who previously served as environment minister, described the timeline as deeply disappointing. Speaking on BBC Radio Foyle, Durkan said the prospect of work not beginning until 2028 at the earliest was "indicative of a lack of urgency."

"People here have been waiting far too long already for this issue to be resolved," he said, adding that he lacked confidence the executive would treat the matter as a financial priority given the ongoing pressures on public spending.

Durkan had attended a briefing with the minister the previous week but said he came away without any meaningful new information to offer his constituents.

A Community Still Waiting

For those living near the Mobuoy site, the announcement offers cautious hope but little immediate relief. With a clean-up timeline potentially stretching into the early 2030s and a cost estimate likely to climb, the full resolution of this environmental crisis remains a distant prospect. What is clear, however, is that after more than a decade of delays, the wheels of remediation are — however slowly — beginning to turn.
