Funds not available for major water infrastructure plans

There is not enough funding available to deliver a number of major infrastructure projects, NI Water has said.

It says the severity of wastewater and drainage development constraints will increase as a result.

The company plans to set out the implications of deferring the Living With Water Plan (LWWP) for Belfast, a £1.9bn programme, next month.

The decision means work to upgrade sewage works at Sydenham, Whitehouse and Kinnegar cannot proceed, and works planned at Glenmachan, Greenisland, Carrickfergus and on the sea outfalls will not start.

NI Water says it will begin a programme of maintenance this spring to "ensure the existing facility operates as effectively as possible".

Last year, the former Infrastructure Minister John O'Dowd said an estimated 50% increase in the cost of the plan was not affordable.

When LWWP was published in 2015, it set out three objectives:

• Protect against flooding
• Enhance the environment
• Provide the capacity to allow further development such as house building

The lack of wastewater infrastructure has been a longstanding concern of developers who said it was preventing economic growth in the city.

Drainage in Belfast was originally designed by Victorian engineers as a combined system, with both sewage and storm water flowing through the same pipes.

That was due to the shape of the city, sitting at the bottom of hills at near-sea level.

In a statement, NI Water said in late 2024, the Department for Infrastructure (DfI) had carried out a review of the LWWP and concluded the original 12-year scale is "no longer achievable".

It added that the delivery cannot be taken through a formal programme, but will instead need to be carried out by individual partners, such as NI Water, at a "scale and pace achievable within available budgets".

"The projects included within the Living With Water in Belfast Plan... are major infrastructure upgrades which require significant and sustained investment over a number of years which is currently not available to NI Water," it added.

"Therefore, the projects have been paused indefinitely."

Belfast City Councillor Anthony Flynn described Thursday's announcement as "not a shock at all".

"It's something that we've known about for decades," he told BBC Radio Ulster's Evening Extra programme.

The Green Party representative said the government has done "nothing" to address the concerns around wastewater infrastructure, which have cropped up over the years.

"That is unacceptable and right now we are seeing over 20 million tonnes of untreated sewage spilling into our waters," he added.

"Every single lake, every single river, every single coastal waterway in Northern Ireland does not meet good environmental quality standards."

Flynn said the issues surrounding water infrastructure were causing delays to new housing being built in the city.

"We have a housing waiting list across Northern Ireland, but particularly in Belfast, that is tens of thousands of households long," he said.

"This could have been dealt with many years ago. The fact is, decisions were not made 20 years ago to deal with this issue."

Alliance assembly member Peter McReynolds, who is the party's infrastructure spokesperson, said the rising cost of the project meant it was "challenging" to deliver it.

"Unfortunately in Northern Ireland people aren't willing to have those conversations about how we actually manage our water," he told Evening Extra.

"These are major, resource-heavy, capital investment-heavy projects. These things require long-term strategic and consistent investment, and strategic planning."
