Uisce Éireann urges Galway households to cut water usage as heatwave puts supplies at risk

In response to a prolonged heatwave that has intensified over the past few weeks, Uisce Éireann, the national water utility, has launched a nationwide appeal for residents to adopt more sustainable water habits. The call comes after a series of extreme weather conditions led to unprecedented levels of water consumption, particularly in the Greater Dublin Area, where daily usage hit a record high of 685 million litres—marking a 6.7% increase compared to the year-to-date average. This surge in demand has raised concerns about long-term water security, prompting the utility to issue urgent warnings and practical advice aimed at reducing unnecessary consumption.

The heatwave, which began in late May and continued into early June, brought unseasonably high temperatures across much of the country. As a result, residential and commercial users alike experienced a sharp uptick in water usage, driven largely by increased outdoor activities such as gardening, swimming, and cleaning. According to Uisce Éireann, these spikes in demand have placed additional strain on existing water treatment facilities, which were already operating near full capacity. While reservoirs and groundwater sources have seen some recovery following a wet winter, experts warn that this temporary relief does not equate to long-term stability, especially given the increasing frequency of extreme weather events linked to climate change.

To address these concerns, Uisce Éireann has initiated a public awareness campaign, emphasizing the importance of responsible water use. A recent survey conducted by Ipsos/B&A on behalf of the utility revealed that nearly one-third of respondents—approximately 31%—consider themselves “unengaged” when it comes to water conservation efforts. This finding highlights a critical gap between public perception and the reality of water scarcity risks. In light of these results, the utility has taken steps to educate the public, offering tools such as an online conservation calculator to help individuals assess and improve their water usage habits.

Margaret Attridge, head of water operations at Uisce Éireann, noted that while the current water supply appears stable, the utility must remain vigilant. She pointed out that the combination of rising temperatures and seasonal fluctuations in rainfall creates an uncertain future for water availability. “Our water system continues to face challenges from rising demand and increasingly unpredictable weather patterns,” she stated. To support these efforts, Uisce Éireann has also begun implementing targeted interventions in certain regions, particularly in areas where aging infrastructure exacerbates the problem.

Mairéad Conlon, asset strategy manager at the utility, highlighted the ongoing struggle to maintain optimal performance at water treatment plants. Although leak rates have decreased significantly—from 49% in 2014 to 35% in 2026—the need to sustain this improvement remains pressing. Raw water supplies, though currently adequate, are under constant pressure due to the demands placed on treatment facilities. Conlon stressed that without collective action from both the public and private sectors, the risk of disruptions to water services will continue to grow.

As the summer progresses, Uisce Éireann plans to expand its outreach initiatives, focusing on communities most vulnerable to water shortages. With the potential for further heatwaves and drought conditions, the utility is preparing for scenarios that could require even stricter conservation measures. The upcoming months will likely see increased collaboration between local authorities, environmental groups, and residents to ensure that water resources are managed responsibly and sustainably.
