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.

The operator of a sea angling business in Wicklow Harbour has spoken out over a faulty storm drain pipe that has been pumping raw sewage into the water next to his berth.

Kit Dunne of Wicklow Boat Charters told the Wicklow People that he has brought the problem with the South Quay outflow pipe to harbour officials and local councillors “time and again” over a number of years.

“I’m investing in a new vessel at a cost of €300,000 and I don’t see how I can develop my business if my new boat is right beside a stinking sewer,” he said.

The harbour, which is also used regularly by Wicklow Swimming Club, was recently subject to a no-swim notice due to pollution from the storm water overflow.

Meanwhile, Cllr Mary Kavanagh recently engaged with Dunne on the matter and said she is following up with the relevant officials.

“Sewage shouldn’t be mixing with surface water and coming out of a overflow storm drain,” she said. “I don’t know yet what is causing it but it is totally unsatisfactory to have sewage going into the harbour. The smells are appalling and you can only imagine the damage that is being caused to marine and sea life.”

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.

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”.

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.

Planners are from today set to review proposals for a controversial €500 million wastewater treatment scheme in North Dublin, as The Irish Times reports.

Clonshaugh near Dublin Airport was chosen in June 2013 as the site for the sewage ‘super plant’ before Irish Water took over the Greater Dublin Drainage project from Fingal County Council last year.

The new plant — second only to the Ringsend wastewater facility in scope — would be connected to a new orbital sewer to Blanchardstown, and an outfall pipe to eject treated wastewater in the sea north of Ireland’s Eye.

Plans for the new sewage processing plant have faced strong local opposition, both from residents adjacent to the Clonshaugh site and connected works and marine professionals concerned about potential environmental risks.

Last October, Howth-based ferryman Ken Doyle expressed his fears of the knock-on effect on fish stocks from any accidental contamination of the local waters from the outfall pipe.

The planning hearing began at The Gresham hotel in Dublin this morning, and The Irish Times has more on the story HERE.

#MarineWildlife - A Howth-based ferryman fears for marine wildlife on and around Ireland’s Eye when a planned sewage outfall pipe begins discharging wastewater in the area.

Ken Doyle of Ireland’s Eye Ferries tells Dublin Live that any accidental contamination of the waters from the pipeline, from Clonshaugh to a mile off the small island immediately north of Howth, could have a disastrous knock-on effect on fish stocks — an issue both for sea anglers and local bird and seal colonies.

Five years ago, Clonshaugh in North Co Dublin was chosen as the location for the capital’s wastewater treatment ‘super plant’.

The scheme will connect a 26km orbital sewer through counties Dublin, Kildare and Meath with an outfall pipeline ejecting waste off Ireland’s Eye.

Doyle noted that when the outflow of raw sewage at Howth Head was ended with the opening of the Ringsend treatment plant, improvements in water quality meant “the bird population increased hugely and it’s all positive but I wouldn’t like it to go back to like it was.”

He adds that he is not opposed to the wastewater scheme in principle — only that he and other local residents and businesses want assurances that the plant will not have any negative impact on the environment.

#Pollution - Cork Harbour, Ringsend in Dublin and more than 40 other Irish riverside or coastal towns and cities in still fail to meet EU sewage standards, according to a damning new EPA report.

RTÉ News has details of the environmental agency’s 2015 Urban Waste Water Treatment Report, which identifies 43 urban areas — 29 of them classed as large towns or cities – that continue to release raw sewage into the sea and rivers across Ireland.

A number of these locations have seen their timetable for tackling such discharges slip by almost two years due to lack of sufficient capital investment, which the EPA decries as “unacceptable”.

In locations such as Youghal and Merrion Strand, the release of untreated waste has been linked to a significant lowering of bathing water quality.

The news is little different from almost three years ago, when the EPA identified the likes of Killybegs in Co Donegal and Cork Harbour as black spots for untreated wastewater.

More recently, Housing Minister Simon Coveney promised that the problem of discharges from a number of communities around Cork Harbour would be solved within the next 18 months, as previously reported on Afloat.ie.

For all you need on the Marine Environment - covering the latest news and updates on marine science and wildlife, weather and climate, power from the sea and Ireland's coastal regions and communities - the place to be is Afloat.ie.

Coastal Notes

The Coastal Notes category covers a broad range of stories, events and developments that have an impact on Ireland's coastal regions and communities, whose lives and livelihoods are directly linked with the sea and Ireland's coastal waters.

Topics covered in Coastal Notes can be as varied as the rare finding of sea-life creatures, an historic shipwreck with secrets to tell, or even a trawler's net caught hauling much more than just fish.

Other angles focusing the attention of Coastal Notes are Ireland's maritime museums, which are of national importance to maintaining access and knowledge of our nautical heritage, and those who harvest the sea using small boats based in harbours where infrastructure and safety pose an issue, plying their trade along the rugged wild western seaboard.

Coastal Notes tells the stories that are arguably as varied as the environment they come from, and which shape people's interaction with the natural world and our relationship with the sea.

Marine Wildlife

One of the greatest memories of any day spent boating around the Irish coast is an encounter with Marine Wildlife. It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. And as boaters fortunate enough to have experienced it will testify, even spotting a distant dorsal fin can be the highlight of any day afloat. Was that a porpoise? Was it a whale? No matter how brief the glimpse, it's a privilege to share the seas with Irish marine wildlife.

Thanks to our location in the North Atlantic, there appears to be no shortage of marine life to observe. From whales to dolphins, seals, sharks and other ocean animals, the Marine Wildlife category documents the most interesting accounts around our shores. And we're keen to receive your observations, your photos, links and video clips, too!

Also valuable is the unique perspective of all those who go afloat, from coastal sailing to sea angling to inshore kayaking to offshore yacht racing, as what they encounter can be of great importance to organisations such as the Irish Whale and Dolphin Group (IWDG). Thanks to their work we now know we share the seas with dozens of species who also call Ireland home. But as impressive as the list is, the experts believe there are still gaps in our knowledge. Next time you are out on the ocean waves, keep a sharp look out!

Weather

As an island in the North Atlantic, Ireland's fate is decided by Weather more so than many other European countries. When storm-force winds race across the Irish Sea, ferry and shipping services are cut off, disrupting our economy. When swollen waves crash on our shores, communities are flooded and fishermen brace for impact - both to their vessels and to their livelihoods.

Keeping abreast of the weather, therefore, is as important to leisure cruisers and fishing crews alike - for whom a small craft warning can mean the difference between life and death - as it is to the communities lining the coast, where timely weather alerts can help protect homes and lives.

Weather affects us all, and Afloat.ie will keep you informed on the hows and the whys.

Marine Science

Perhaps it's the work of the Irish research vessels RV Celtic Explorer and RV Celtic Voyager out in the Atlantic Ocean that best highlights the essential nature of Marine Science for the future growth of Ireland's emerging 'blue economy'.

From marine research to development and sustainable management, Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. Whether it's Wavebob ocean energy technology to aquaculture to weather buoys and oil exploration, the Marine Science category documents the work of Irish marine scientists and researchers and how they have secured prominent roles in many European and international marine science bodies.

Power From The Sea

The message from the experts is clear: offshore wind and wave energy is the future. And as Ireland looks towards the potential of the renewable energy sector, generating Power From The Sea will become a greater priority in the State's 'blue growth' strategy.

Developments and activities in existing and planned projects in the pipeline from the wind and wave renewables sector, and those of the energy exploration industry, point to the future of energy requirements for the whole world, not just in Ireland. And that's not to mention the supplementary industries that sea power projects can support in coastal communities.

Irish ports are already in a good position to capitalise on investments in offshore renewable energy services. And Power From The Sea can even be good for marine wildlife if done properly.

Aside from the green sector, our coastal waters also hold a wealth of oil and gas resources that numerous prospectors are hoping to exploit, even if people in coastal and island areas are as yet unsure of the potential benefits or pitfalls for their communities.

Changing Ocean Climate

Our ocean and climate are inextricably linked - the ocean plays a crucial role in the global climate system in a number of ways. These include absorbing excess heat from the atmosphere and absorbing 30 per cent of the carbon dioxide added to the atmosphere by human activity. But our marine ecosystems are coming under increasing pressure due to climate change.

The Marine Institute, with its national and international partners, works to observe and understand how our ocean is changing and analyses, models and projects the impacts of our changing oceans. Advice and forecasting projections of our changing oceans and climate are essential to create effective policies and management decisions to safeguard our ocean.

Dr Paul Connolly, CEO of the Marine Institute, said, “Our ocean is fundamental to life on earth and affects so many facets of our everyday activities. One of the greatest challenges we face as a society is that of our changing climate. The strong international collaborations that the Marine Institute has built up over decades facilitates a shared focusing on our changing ocean climate and developing new and enhanced ways of monitoring it and tracking changes over time.

“Our knowledge and services help us to observe these patterns of change and identify the steps to safeguard our marine ecosystems for future generations.”

The Marine Institute’s annual ocean climate research survey, which has been running since 2004, facilitates long term monitoring of the deep water environment to the west of Ireland. This repeat survey, which takes place on board RV Celtic Explorer, enables scientists to establish baseline oceanic conditions in Irish waters that can be used as a benchmark for future changes.

Scientists collect data on temperature, salinity, water currents, oxygen and carbon dioxide in the Atlantic Ocean. This high quality oceanographic data contributes to the Atlantic Ocean Observing System. Physical oceanographic data from the survey is submitted to the International Council for the Exploration of the Seas (ICES) and, in addition, the survey contributes to national research such as the VOCAB ocean acidification and biogeochemistry project, the ‘Clean Atlantic’ project on marine litter and the A4 marine climate change project.

Dr Caroline Cusack, who co-ordinates scientific activities on board the RV Celtic Explorer for the annual survey, said, “The generation of long-term series to monitor ocean climate is vital to allow us understand the likely impact of future changes in ocean climate on ecosystems and other marine resources.”

Other activities during the survey in 2019 included the deployment of oceanographic gliders, two Argo floats (Ireland’s contribution to EuroArgo) and four surface drifters (Interreg Atlantic Area Clean Atlantic project). The new Argo floats have the capacity to measure dissolved ocean and biogeochemical parameters from the ocean surface down to a depth of 2,000 metres continuously for up to four years, providing important information as to the health of our oceans.

During the 2019 survey, the RV Celtic Explorer retrieved a string of oceanographic sensors from the deep ocean at an adjacent subsurface moored station and deployed a replacement M6 weather buoy, as part of the Irish Marine Data Buoy Observation Network (IMDBON).

Funded by the Department of Agriculture, Food and the Marine, the IMDBON is managed by the Marine Institute in collaboration with Met Éireann and is designed to improve weather forecasts and safety at sea around Ireland. The data buoys have instruments which collect weather and ocean data including wind speed and direction, pressure, air and sea surface temperature and wave statistics. This data provides vital information for weather forecasts, shipping bulletins, gale and swell warnings as well as data for general public information and research.

“It is only in the last 20 years, meteorologists and climatologists have really began to understood the pivotal role the ocean plays in determining our climate and weather,” said Evelyn Cusack, Head of Forecasting at Met Éireann. “The real-time information provided by the Irish data buoy network is particularly important for our mariners and rescue services. The M6 data buoy in the Atlantic provides vital information on swell waves generated by Atlantic storms. Even though the weather and winds may be calm around our shores, there could be some very high swells coming in from Atlantic storms.”
