The Rivers Trust supports the findings of new report that rings alarm bells about the critical state of water quality management in Northern Ireland and Great Britain.

The Surfers Against Sewage Water Quality Report for 2023 says that in Northern Ireland, there is a lack of the discharge of raw sewage into waters at popular beaches and inland waterways bathing sites — and both anecdotal reports and water quality data suggest the problem is significant.

Mark Horton, all-Ireland director of The Rivers Trust said the report “underscores longstanding environmental concerns we continually raise. The evidence of the effects of sewage and pollution is there and clear.

“The severe algal bloom in Lough Neagh is a stark illustration of the consequences of poor environmental stewardship in Northern Ireland.”

NI’s 2,398 operational sewage overflows — and the sparse data on their performance — emphasise an urgent need for investment in increased monitoring and more transparency so the public can make informed decisions and remedial actions can be taken, The Rivers Trust says.

Horton added: “The management of sewage in Northern Ireland shows a critical need for investment and modernisation. With the absence of a functioning Stormont Executive and no independent environment agency, decisive actions to protect and restore water quality are practically impossible.

“This inaction is unacceptable. Water users in Northern Ireland deserve the same level of safety and information as those elsewhere. Ultimately, we need proper resourcing of Northern Ireland Water to enable it to put in place real-time sewage alerts, so swimmers, surfers and anglers can protect themselves from direct discharges of untreated sewage.”

Horton acknowledged NI water’s plans to deploy monitoring systems by 2024 as “a positive step”, but cautioned that “the lack of clarity on how data will be dissemination and public accessibility to the data remains a concern”.

“Real-time, accessible water quality information isn’t just a nice-to-have; it’s a necessity for the health and safety of our communities and ecosystems,” he said.

Europe’s largest phosphorus extraction reactor has been installed at the Ringsend wastewater treatment plant in Dublin, as RTÉ News reports.

Úisce Éireann (formerly Irish Water) says the reactor — which is extracting phosphorous to be turned into agricultural fertiliser — will help protect water quality in the lower River Liffey and Dublin Bay which have experienced potentially harmful algal blooms in recent years.

The new addition is part of a €500 million upgrade works at the Ringsend facility, which treats 40% of all sewage generated in Ireland — well beyond its capacity.

The Environmental Protection Agency (EPA) says as much as 500 million litres of potentially untreated wastewater is being released into Ireland’s rivers and coastal waters every day.

As the Irish Independent reports, the agency warns that it will take decades, and billions of euro, to correct the problem — but as yet Irish Water has “no clear action plan or time frame” for remedial works at many of what the EPA identifies as priority areas.

As of the middle of 2022, as many as 32 small towns and villages were discharging raw sewage as they have no wastewater treatment infrastructure.

Overall, the EPA claims that 49% of Ireland’s sewage — far above the EU average of 10% — is “still not treated to the standards set to protect the environment”, according to the agency’s programme manager Noel Byrne.

Water quality may benefit from a new 50 million euro funding scheme to provide treatment in small communities without access to public wastewater infrastructure.

Some 547 villages and settlements may be eligible for the scheme which aims to reduce risks to public health and prevent pollution.

It will be funded from the National Development Plan, and will run until 2025, according to Minister for Housing and Local Government Darragh O’Brien.

A baseline survey in 2021 quantified that a total of 547 communities did not have access to the collection and treatment infrastructure provided by Irish Water.

“The improved wastewater services will enable local authorities to work in partnership with the community to enable villages and settlements to be better places to live, work and visit, to support overall Government objectives under “Housing for All”, and give practical effect to our vision for a vibrant rural Ireland,” he said.

The new measure will provide 85% of Exchequer funding through the Department of Housing, Local Government and Heritage, with the remaining 15% in funding coming from the relevant local authority.

The first phase of funding announced this week will focus on areas of “most need”, based on housing and environmental criteria.

The Government’s “Our Rural Future” policy includes measures to address the water and wastewater infrastructural deficits and to support the revitalisation of rural towns and villages.

The baseline review conducted in 2021 recommended that, to ensure all public investment for this measure was sustainable, environmentally and economically justified, the initial investment needed to be directed at carefully selected demonstration projects.

Water treatment in the capital is not fit for purpose, says the Green Party as it calls for action to improve water quality in Dublin Bay.

The party’s Dun Laoghaire General Election candidate Ossian Smyth told RTÉ News that existing development levies should fund badly needed improvements to the city’s water infrastructure.

Green Party MEP Ciarán Cuffe added that was not acceptable for large parts of Dublin Bay to be unavailable to bathers in the summer months.

It comes after a series of bathing spot closures around the bay last summer — though some of these were prompted by algal blooms not directly related to the release of wastewater.

The Irish National Sailing & Powerboat School (INSS) has expressed its frustration over the second discharge this month of wastewater into Dublin Bay, which has seen new bathing bans issued at several popular swimming spots in the capital.

While the latest notice does not apply to the waters inside Dun Laoghaire Harbour, the INSS says it has still had to activate its ‘unclean water procedure’ as Salthill beach, from where it usually operates, and other locations woke up to an ‘orange slick’ on the shoreline this morning (Tuesday 25 June). This slick has since been confirmed by the local authority as an algal bloom "not directly associated" with the wastewater overflow.

The procedure involves alterations to activities, use of small keelboats instead of dinghies if appropriate, and stringent instructor supervision to ensure people are on rather than in the water.

While afloat, all safety boats must carry hand-sanitising wipes, and children must regularly wash their hands. Shore side, extensive hand-washing, sanitising gels and a focus on good hygiene practises minimises the risk as much as possible.

“On this occasion, we have been relatively lucky to still be able to operate within the harbour,” said Glyn Williams, the school’s communications and marketing manager.

“However, it’s not good enough that we find out about this later in the day,” he added, referring to the initial reports of the latest bathing ban last night. “The treatment plant operator knew they were discharging. Why not tell everyone straight away?”

Chief instructor Kenneth Rumball also noted that the summer sailing season for children is only 12 weeks long, and with the current water notices lasting until at least this Thursday “we now have six days of a short summer lost to this”.

Responding to Irish Water’s claim that the latest overflow ‘happened as it should have happened’, the school said this cuts little ice with the parents of children attending the its courses.

“Parents are equally as exasperated as we are. While all those we spoke with earlier this morning are understanding, they equally feel that Irish Water/the treatment plant operator should get this solved more quickly than they are currently doing.”

Following similar calls by the likes of Green Party Councillor Ossian Smyth, the INSS is urging those with responsibility to immediately progress upgrades for the sewage system at Ringsend Treatment Plant to cope with heavy rainfall — something Irish Water says would require a “huge amount” of investment.

The school also calls for more transparent communication, in real time, if and when discharges are occurring, coupled with pre-emptive warnings and same-day water sampling results.

Commenting on how these water quality issues affect the development of Dun Laoghaire Harbour as a marine leisure destination, Glyn Williams said: “We have to make sure that we get the basics in place before we undertake large scale plans.

“There’s no point in expending time and money when the most basic requirement for water sports is not in place: safe water to operate in.”

Heavy rains in recent days have led to another wastewater overflow at the Ringsend treatment plant, as well as other pumping stations, that has prompted a new swimming ban at several Dublin Bay beaches.

It marks the second time this month that bathing has been prohibited at Dollymount Strand, Seapoint, Sandycove and the Forty Foot at Sandycove.

Both Dublin City and Dun Laoghaire-Rathdown councils say their bans will remain in place pending test for water quality, the first results of which are due on Thursday — in a week where Met Éireann forecasts higher temperatures.

While the bans do not affect Dun Laoghaire Harbour or other beaches in either council area, organisers of water-based sporting events have been advised to take note, as The Irish Times reports.

Notices will be put up on beaches today, Tuesday 25 June, according to RTÉ News.

Update 4.30pm: Dun Laoghaire-Rathdown County Council says tests on an ‘orange slick’ at Sandycove Beach confirm the presence of Noctiluca scintillans, a form of algae, and not raw sewage.

In a statement, the council said the non-toxic species is “a natural summer phenomenon in response to long day length, high nutrients and warm water” and is “not directly associated with the waste water overflows associated with the temporary bathing prohibition”.

Inland Fisheries Ireland (IFI) has prosecuted Irish Water for two separate pollution incidents which occurred in Cavan last summer.

On Thursday 6 June, Judge McLoughlin twice convicted Irish Water at Cavan District Court under the Fisheries (Consolidation) Act 1959 for allowing harmful substances to enter the water on two occasions in June last year.

Over 600 fish were killed as a result of one pollution incident while an important habitat for spawning and young fish was damaged as a result of the other.

The court heard evidence from fisheries inspector Cormac Goulding that on 19 June 2018, staff from IFI noticed that the river downstream of the Ballinagh Treatment Plant in Cavan was in very poor condition.

The water was cloudy and the river was covered in sewage fungus and algal growth.

Following an investigation, it was discovered that untreated sewage was being discharged from the water treatment plant and at the pumping station further downstream.

Irish Water issued a report to IFI in response to the prosecution which revealed that their computerised monitoring system had been offline for six days, which meant that no alerts had been received about the problem.

The effluent was being discharged into aquatic habitat suitable for spawning or young trout.

Judge McLoughlin fined Irish Water €3,000 and total costs of €4,679 were awarded to IFI.

A separate pollution incident occurred a few days later on 25 June 2018 in Cavan Town River.

Judge McLoughlin heard evidence from Ailish Keane, senior environmental fisheries officer at IFI, about how the pollution incident resulted in the death of hundreds of fish including 687 native brown trout.

An investigation found that the fish kill was caused by the release of sewage effluent into the river from an overflow culvert located under Farnham Street Bridge.

Irish Water were again convicted and fined €4,000 plus costs of €4,346.

Milton Matthews, director of the North Western River Basin District at IFI, said: “In both cases in Cavan, harmful material was discharged into local rivers and in Cavan town this resulted in a large kill of over 600 native brown trout, of all age classes.

“As it can take years for a waterbody to recover to its former condition following pollution incidents, it is crucial that robust management systems are in place to prevent avoidable incidents which can have a serious impact on our wild fish and their natural habitat.

“The restoration of the aquatic habitat and the maintenance of water quality is vital if we are to enable wild fish populations to recover naturally.

“We are working to protect, conserve and develop our natural fisheries resource which is of significant recreational and economic value to communities in Cavan and across the country.”

Dublin local authorities have issued bathing ban notices for a number of popular swimming spots after a sewage leak at the Ringsend wastewater treatment plant, as RTÉ News reports.

Swimming is currently prohibited along the coast between Dollymount in North Dublin and White Rock Beach in Killiney on the Southside, just beyond Dublin Bay.

The string of bathing spots includes the enduringly popular Forty Foot in Sandycove.

Moreover, Sandymount and Merrion just south of Ringsend — where the wastewater plant was in the news earlier this year over a discharge in the Liffey — have been landed with a swimming ban for the entire 2019 bathing season due to their overall poor water quality.

Almost 30 sewage schemes across Ireland fall short of EU directives on wastewater treatment, as The Green News reports.

The European Court of Justice ruling from this past Thursday 28 March now means Ireland could be liable to significant fines if the problem schemes are not addressed.

Among the court’s findings were that Cork city’s strained wastewater treatment scheme was subject to more than 800 spillages of untreated sewage in 2015 alone.

Sensitive areas in Killarney, Longford, Dundalk and Tralee, among others, were also affected by untreated wastewater discharges for which the State has been reprimanded by European judges.

In addition, the State as found guilty of failing to provide for secondary treatment at a number of problem sites including Cobh in Cork Harbour, the fishing harbours of Arklow and Killybegs, and Ringsend in Dublin — the latter of which was the scene of a discharge of ‘activated sludge’ only a month ago.

The Department of Housing and Local Government says it has provided Irish Water “with the necessary resources to both tackle the deficiencies identified by the [ECJ] as well as providing the infrastructure which will underpin the future sustainable development of our country.”

Part of the State’s defence in this case were occasions of ‘unusually heavy rainfall’ that overwhelmed the country’s wastewater management systems.

Such conditions are also linked to the leeching of nitrates and phosphates from agricultural sites causing seaweed blooms in coastal areas, as highlighted by a recent academic report.

The news also comes after oral hearings began into a long-planned €500 million wastewater treatment scheme for North Dublin that faces strong local oppositions.

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
