EU SWIM Project launches during the 2019 Bathing Water Season

Debra Castles tells us about the EU SWIM Project – an innovative cross-border project that wants to change how bathing water quality is monitored, by using predictive models to give near real-time results.

During the bathing water season from 1 June 2019 the EU SWIM project will provide invaluable, real-time information on water quality for the public on both sides of the border. There are currently nine SWIM beaches. Three are in the Republic: Enniscrone (Co Sligo), Lady’s Bay (Co Donegal), and Clogherhead (Co Louth); six are in Northern Ireland; Castlerock (Co Antrim), Portrush – Curran (Co Antrim), Waterfoot (Co Antrim), Ballyholme (Co Down), Ballywalter (Co Down), Newcastle (Co Down). Some of these beaches have Blue Flag status, and this project will complement and reinforce the standards that users expect when they visit these beaches to enjoy all they have to offer.

The project is funded by the INTERREG VA Programme which focuses on overcoming the issues that arise from the existence of a border, including environmental issues. The EU SWIM Project will make a significant contribution towards meeting the EU’s Bathing Water Directive, and therefore contribute towards our shared seas being safer places to swim and enjoy.

The EU SWIM Project combines the expertise of lead partner University College Dublin, and Northern Irish project partners Agri- Food Biosciences Institute and Keep Northern Ireland Beautiful. The project aims to develop a system that will allow bathers to check the water quality of their chosen bathing spots live before taking a dip. Developing a bathing water quality prediction model will directly tie into software to support the collection of data and delivery of information to the public.

Professor Gregory O’Hare of University College Dublin explains

“The EU SWIM Project is not only developing a bathing water prediction model and enabling water sampling and microbial tracking, it will also result in the creation of an app and with real-life updates on the new website; which crucially promotes good management, environmental standards and sustainability for beaches on the island of Ireland.”

Cross Border School Collaboration

As part of the project two weather stations have been deployed close to 2 of the EU SWIM beaches at Scoil Chríost Rí, Enniscrone, County Sligo and St Patrick’s Primary School near Waterfoot beach in Glenariff, County Antrim. This approach has facilitated an exciting cross border aspect, as both schools can link up and share data coming from their SWIM weather stations and compare their results. During beach visits in October 2018 the EU SWIM team had the opportunity to spend time looking at the instalment at St Patrick’s and talking to the children about how the data works.

The principal of St Patrick’s Primary School, Roisin McCarry, kindly facilitated a demonstration of the weather station data to the pupils and she commented “at the minute, St. Patrick’s Primary School is the only school in this area to have a weather station. The information is very detailed for primary school use, but we hope that by working with UCD, AFBI and Keep Northern Ireland Beautiful, we will be able to come up with ways to use the data in our projects on weather, the environment as well as linking with other schools to work on joint projects”.

Weather Stations and River Sensors

A major element of the programme roll out has been the deployment of the weather stations to assist with the predictive element in conjunction with the river sensors and gauges. There has also been a wide collaboration with other partners to gather as much predictive data as possible, for example. Northern Ireland Water, EPA, OPW, Met Eireann and Acclimatize, another INTERREG-funded project at UCD.

The water quality updates will be going live for the bathing water season between June and September 2019.

Project Funding: this research takes place across sites in Northern Ireland and the Republic of Ireland – a cross-border initiative supported by the EU’s INTERREG VA funding scheme. The project is match-funded by the Department for Agriculture, Environment and Rural Affairs (DAERA) in Northern Ireland and the Department of Housing, Planning and Local Government in Ireland.

Who is involved?

Quite simply, everyone in Ireland has a role to play. This can be from something as simple as making sure you don’t pollute your local stream, or a local community working together to establish a Rivers Trust to enhance the rivers and lakes in their area, to a Government Department or Agency helping a Minister implement a new policy to help protect and enhance all our water bodies.

This website has been developed and is maintained by the Environmental Protection Agency, and is a collaboration between the Department of Housing, Planning and Local Government, the Environmental Protection Agency, and the Local Authority Waters Programme.


Local Authority Waters Programme

The Local Authority Waters Programme coordinates the efforts of local authorities and other public bodies in the implementation of the River Basin Management Plan, and supports local community and stakeholder involvement in managing our natural waters, for everyone’s benefit.


Environmental Protection Agency

The EPA is responsible for coordinating the monitoring, assessment and reporting on the status of our 4,829 water bodies, looking at trends and changes, determining which waterbodies are at risk and what could be causing this, and drafting environmental objectives and measures for each.


Department of Housing, Local Government and Heritage

The Department is responsible for making sure that the right policies, regulations and resources are in place to implement the Water Framework Directive, and developing a River Basin Management Plan and Programme of Measures that will be implemented after public consultation and sign off by the Minister.
