The Dublin Urban Rivers LIFE (DURL) project, a joint venture between South Dublin and Dún Laoghaire-Rathdown County Councils, has prevented roughly 13 million litres of polluted wastewater from entering Dublin rivers annually by using Esri Ireland’s digital mapping system. The project aims to improve water quality by finding and removing household appliances that are expelling polluted water into rivers in two catchment areas. Esri’s ArcGIS system has assessed over 8,300 homes to date and identified over 1,000 misconnected appliances. 

Misconnections tend to occur when homes are renovated or extended, and new appliances are installed. Some washing machines, dishwashers, sinks, and toilets can be mistakenly connected to the rainwater or stormwater drainage pipe instead of the sewage pipe, resulting in polluted water being discharged into local rivers and streams. 

DURL’s field-based teams use ArcGIS Field Maps to view maps of the surface water drainage network on their mobile devices. Using this app, they lift manholes in residential areas, record signs of pollution in stormwater drains, and upload their findings directly to a central dashboard.

The project team has also developed a “Lite” version of the ArcGIS solution that can be used by other urban councils across Ireland and Europe as the basis for their own water quality improvement processes. 

Dermot O’Kane, Head of Sales, Esri Ireland, said: “This project is making a huge difference to the water quality and aquatic biodiversity in our Dublin rivers, making it an incredibly important project to work on. This technology is an efficient, digital process for inspecting suspected pollution which is easy to use and resulting in both cost and time savings for these county councils. We designed this solution with the future in mind, and we’re excited to see the technology being used elsewhere to improve the water quality for more rivers and waterways across Ireland and Europe.”

Briana Shiels, Project GIS Officer, Dublin Urban Rivers LIFE, said: “The driver for the project is always the quality of the rivers. ArcGIS enables us to find as many houses as possible with misconnected appliances, as efficiently as possible, to help Dublin’s rivers reach a good standard of water quality. Project information is transparent to everyone working on the project, whether in the field or in the office.”

Lorraine Beirne, Project Co-ordinator, Dublin Urban Rivers LIFE, said: “On average, 8% of domestic properties in Dublin have a misconnection and the DURL Project has identified a misconnection rate of greater than 30% in some housing estates as we now have a better system to pinpoint these properties and take action far more efficiently. With ArcGIS, we have built a replicable, standard solution with products that most local authorities in Ireland know and use already.”

Minister for Agriculture, Food and the Marine, Charlie McConalogue was joined by Ministers of State Pippa Hackett and Malcolm Noonan on the shores of Lough Ennell on Thursday (7 March) to officially launch the €60 million Water EIP ‘Farming for Water’ project aimed at improving water quality at local, catchment and national levels.

The project is a collaborative approach between the Department of Agriculture, Food and the Marine and the Department of Housing, Local Government and Heritage, working in partnership with the agri-food industry to improve water quality.

The Department of Agriculture, Food and the Marine will support the project through the provision of funding of €50 million for participating farmers, co-funded by the National Exchequer and the EU, with the objective of involving 15,000 farmers in priority areas nationally. The Department of Housing, Local Government and Heritage will provide the administrative support for the project to the value of €10 million.

Through this European Innovation Partnership (EIP-AGRI) project, an operational group has been established by the Local Authority Waters Programme (LAWPRO), in partnership with Teagasc, Dairy Industry Ireland (DII) and Bord Bia, and with the support of other stakeholders, to work in partnership with farmers in the implementation of a number of targeted actions at farm level to improve water quality.

Minister McConalogue said: “This government wants to improve water quality and also wants to ensure Ireland and Irish farmers secure a nitrates derogation from 2026. Today’s investment of €60 million is proof of the Government’s commitment to support farmers in their efforts to achieve those dual aims.

“The future of our farms, and the families on those farms, are largely dependent on successful water quality outcomes and I am absolutely confident farmers will not be found wanting in delivering those outcomes. The success of this EIP will be a source of inspiration, encouraging more leadership, more action and more engagement with water initiatives across all farm types and farm sizes.

“This project is a key component in our ongoing efforts to improve water quality and the sustainability of our agricultural practices at a national level, but it is just one element. It is part of a suite of measures to bolster those efforts. This includes a national multi-actor Water Quality Advisory Campaign, led by Teagasc as well as increased compliance and enforcement activity across my own Department and the Local Authorities.

Minister for Land Use and Biodiversity, Senator Pippa Hackett said: “As minister with responsibility for both EIPs and biodiversity, I am delighted to support this flagship EIP, which demonstrates this Government’s commitment to maintaining and improving water quality in Ireland.

“This is our largest EIP to date, both in terms of funding and in its ambition in relation to the role that agriculture can play in improving water quality and, by extension, the benefits for nature and biodiversity that will accrue as a result.”

Minister of State for Nature, Heritage and Electoral Reform, Malcolm Noonan said: “Our rivers, lakes, estuaries and bays are at the heart of what we value about Ireland’s environment. Improving the quality of their waters is vital — not just for nature and wildlife, but also for public health and wellbeing — and it’s by working together that we will yield the greatest results.

“This unique and innovative collaboration brings the farming community, the food processing industries, LAWPRO, ASSAP and the two government departments together with a single aim. It is testament to the commitment of Government departments and the agricultural sector in taking ownership of their role in improving water quality.”

Anthony Coleman, director of LAWPRO, representing the Operational Group said: “This Water EIP represents a significant opportunity for us to engage and collaborate with the agricultural sector to deliver improvements in water quality throughout the country. We will be working hand-in-hand with farmers to introduce more nature-based solutions as well as supporting community organisations to work on delivery of water quality measures that will benefit our environment, economy and society.

“This water stewardship initiative follows catchment science principles and focuses on multiple benefits, including climate and biodiversity. I am delighted that this project is now underway and we have a team in place who will work in conjunction with our partners Teagasc, ASSAP, Dairy Industry Ireland and other stakeholders.”

Three Sinn Féin MLAs have brought a motion to the newly restored Stormont Assembly for action to save Lough Neagh from its pollution crisis, as The Irish Times reports.

MLA for North Antrim, Philip McGuigan described the situation on the lough as an “ecological catastrophe”.

“The work of saving Lough Neagh and repairing the damage to its ecology and environment and that of its tributaries and surrounding land must be a top priority for the Executive in the time ahead,” he told the Assembly on Tuesday (13 February).

The motion comes on the heels of last summer’s spate of toxic blue-green algae blooms, which caused the deaths of numerous pets and was blamed for the collapse of the lough’s renowned native eel fishery.

Untreated wastewater and agricultural run-off — not to mention climate change, invasive species such as the zebra mussel, and political inaction due to the collapse of the Northern Ireland Executive — have been singled out as reasons behind the current crisis.

The Irish Times has more on the story HERE.

Inland Fisheries Ireland (IFI) has welcomed the outcome of a case it brought against Uisce Éireann involving sewage pollution of the Cavan town river.

A fine of €2,000, plus costs and expenses of €3,197, were imposed at a hearing on the matter at Cavan District Court on Friday 1 December.

It comes after IFI had previously secured prosecution in October against the State water utility for pollution of the Ballinagh River in Co Cavan which killed 160 fish.

The court heard that in the wake of ongoing issues at the Uisce Éireann wastewater treatment plant at Ballinagh, senior IFI fisheries environmental officer Ailish Keane had taken samples for analysis following the pollution event in Cavan town on 3 February this year.

These test samples, taken downstream from the plant, showed high levels of pollutants, with large amounts of sewage fungus — bacteria, fungus and algae that reduce oxygen levels — visible on the bed of the river.

Commenting on the verdict, Dr Milton Matthews, director of IFI’s North-Western River Basin District said: “We welcome the outcome in this case. The presence of sewage fungus in the river is indicative of chronic organic pollution of the Cavan town river at this location, rather than an isolated incident — with significant impact on fish, invertebrates and all aquatic life in the river.

“There were significant breaches of the licence emission limits for biochemical oxygen demand (BOD) — oxygen required to break down organic matter in the water — and high ammonia levels.

“Sample results taken at the location indicated that ammonia levels were over 115 times higher than permitted discharge limits, and eight times higher than permissible for BOD limits as stipulated for this treatment plant.”

The conviction was secured under Section 171 of the Fisheries (Consolidation) Act 1959 — legislation regarding protection of fishing waters from harmful pollutants.

Members of the public are encouraged to report instances of water pollution, illegal fishing, habitat destruction or fish kills to IFI’s confidential number at 0818 34 74 24.

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.

Warning signage is being removed from locations around Lough Neagh following this past summer’s blooms of toxic blue-green algae.

But as BBC News reports, it could be years before the ecological impact on the lough is fully understood.

Ulster Angling Federation chair Gary Houston claimed that the collapse of the Lough Neagh fly, attributed to the cyanobacteria blooms, has had a knock-on effect on all other species in the area — most notably its native trout and eels.

A spokesperson for the Northern Ireland Environment Agency (NIEA) said the fly species was not previously monitored as it was “commonplace and not a protected feature” but confirmed they are “a key trophic (food) component of the Lough Neagh ecosystem”.

“We’ve been damaging the ecosystem in Lough Neagh now for 60 years or so and we’ve been doing it knowingly for 50 years, but we’ve got away without the acute impacts [until now],” said Dr Adam Mellor of the Agri-Food and Biosciences Institution (AFBI).

All parties acknowledge that the current crisis is the result of multiple factors over decades — including climate change, changes in agriculture and the presence of invasive species — and some believe it could take just as long to turn it around.

New predictive technology being developed in Estonia could help prevent the spread of pollution from shipwrecks.

Estonia’s public broadcaster ERR News reports on the monitoring system created by marine scientists at Tallinn University of Technology (TalTech) that may forecast where fuel will spread in the water from a hazardous wreck site.

Estonia’s coastline on the Gulf of Finland, Gulf of Riga and Baltic Sea has a large number of decades-old shipwrecks which are increasingly prone to fuel leaks as they age.

So far the results are promising, with TalTech’s predictive computer models — using current and wave data from Estonian waters — matching real-world data collected from smart buoys placed at a number of coastal sites.

More than half of Ireland’s bathing waters were affected by swimming bans this past summer, an investigation by Noteworthy has revealed.

While four in five coastal and inland bathing spots were classed as excellent in 2022, that statistic runs counter to a wave of swimming prohibitions at beaches and other areas around Ireland in recent years.

This is due to various problems with pollution caused by wastewater release and other factors, the report indicates.

And the issue is being exacerbated by climate change, as wetter conditions lead to overflow from treatment plants operating below EU standards, not to mention runoff from farmland and other surface waters.

Lough Neagh “isn’t just dying, it’s been killed” by a combination of human-made factors, one conservationist has declared as the crisis around toxic blooms of blue-green algae continues.

Speaking to The Irish Times, Friends of the Earth NI director James Orr says the situation “has literally blown people’s trust in the health of the lough out of the water”.

As previously reported on Afloat.ie, the lough — which is the source of nearly half of Northern Ireland’s drinking water — is in crisis due at least in part to the affects of pollution from untreated wastewater and agricultural run-off, as anglers and other groups have claimed.

Similar blooms of cyanobacteria have been recorded across the region, such as on the Lower Bann — which has lost at least one long-standing watersport business to the “unsustainable” situation — and with the latest confirmed at Lough Ross in Crossmaglen.

The issue prompted protestors to hold a ‘wake’ for Lough Neagh last weekend, as others lamented the collapse of the lough’s renowned eel fishery and even the Catholic and Anglican archbishops of Armagh were moved to call for immediate government intervention to help reverse “an environmental disaster”.

In recent days the SDLP has made a renewed bid to recall the Stormont assembly to address the crisis — the lack of a functioning devolved government in Northern Ireland since February 2022 being cited as one of a combination of factors that’s led to the current state of affairs.

Peter Harper of the Lough Neagh Partnership tells The Irish Times that other salient factors include the impact of the invasive Zebra mussel as well as climate change, which has raised the temperature at the bottom of the lough by one degree, in turn contributing to wetter weather that feeds the cycle of pollution from farmland and an overwhelmed sewage system.

“The lough’s in crisis,” says Ciara Laverty of the Lough Neagh Partnership. “The ecology’s changing, unless we do something drastic about it now. Decades of neglect have led us to this point.”

The Irish Times has more on the story HERE.

Causeway Coast and Glens councillors have echoed growing concerns over the state of the aquatic environment following recent blooms of toxic blue-green algae, as the Belfast Telegraph reports.

Alliance Councillor Peter McCully tabled a motion at last week’s Environmental Services Committee Meeting that emphasised the “detrimental impact these blooms have had on local businesses”.

As previously reported on Afloat.ie, at least one long-standing business on the Lower Bann has announced its closure, claiming its future is “unsustainable” given the likelihood of dangerous cyanobacteria blooms happening “on a yearly basis”.

Cllr MuCully said the response from Northern Ireland’s Department for Agriculture, Environment and Rural Affairs (DAERA) to this summer’s incidents is “not sufficient” and his motion calls for DAERA to convene cross-party talks across all affected council areas to develop and action plan.

Lough Neagh has also been affected by toxic blue-green algae blooms in recent months, with angling groups claiming that the lough is “dying” due to the affects of pollution from untreated wastewater and agricultural run-off.

The lough’s eel fishermen have added their voices to the call for action, saying their industry has collapsed this season.

"Never have I seen so many eel fisherman resorting to scale fishing in order to make some form of income,” one co-op member told the Irish News, which has more on the story HERE.

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.
