Uisce Éireann continues to appeal to customers in Limerick to conserve water as increased use means supplies are being used faster than water can be treated and stored in local reservoirs. As a result of high demand, Uisce Éireann has taken proactive measures to safeguard water supplies by maximising treated water production, repairing leaks and bursts and optimising network operations to maintain supply for customers amid continued warm and dry weather conditions.
Uisce Éireann is continuing targeted tankering operations in Bruff, Doon (Lacka), Cappamore-Foileen, Pallasgreen, Old Pallas, Nicker and Newcastlewest to supplement local water supplies and maintain continuity of service for customers while treated water supplies remain under pressure.
The continuation of nighttime restrictions in parts of Limerick is essential to allow treated water reservoirs to recover and ensure daytime supply for homes, businesses and essential services.
- Nighttime restrictions remain in place each night from 10pm to 8am in the following areas: Knocklong, Ballyagran, Coolcappagh, Castlemahon, Newcastle West, Dromcollogher, Pallasgreen, Old Pallas and Nicker.
- Additional nighttime restrictions will be introduced tonight only, from 10pm until 11am on 25 July, in the following areas: Kiloughteen, Monagea, Crean, Camas, Killeline, Knockane, Shangarry and Cullenagh.
Uisce Éireann is continuously monitoring water levels in Limerick and adjusting operations daily based on demand, usage, and weather conditions.
A nationwide Water Conservation Order is now in effect until Wednesday, 26 August 2026 to protect public water supplies now and in the months ahead for homes, businesses, farms, hospitals, vulnerable customers and essential services.
Brian Harrington, Operations Manager with Uisce Éireann, said: “We want to thank customers across Limerick for the efforts they have already made to conserve water. While this is helping, demand remains high and treated water supplies continue to be under pressure. We are asking everyone to keep doing what they can to reduce water use this weekend so that we can protect supplies and maintain essential water services."
Uisce Éireann is continuing to ask customers to take practical steps to conserve water at home, including taking shorter showers, fixing leaks and leaking toilets, and avoiding the use of hosepipes or sprinklers in the garden. A garden hose or sprinkler can use more than the average family uses in a full day. As the Water Conservation Order is being extended nationwide, it applies to all public water supplies across the country for the specified period. Uisce Éireann’s customer care team remains available for all customer queries.
We would also ask the public to report any leaks they see on the public network which may be visible in the dry conditions by contacting Uisce Éireann at 1800 278 278 or on our Report a Leak page.
Customers can also use Uisce Éireann’s online Water Calculator to better understand their household water use and identify simple ways to save water every day.

Previous Updates
Uisce Éireann is asking customers in Limerick to conserve water as increased use during the current spell of warm weather means supplies are being used faster than water can be treated. While raw water sources remain stable, the level of demand is placing pressure on the treatment process. This means treated water is being used more quickly than it can be produced and stored in local reservoirs. Periods of sustained high demand can lead to reduced pressure and, in some cases, interruptions to the availability of water for customers. As a result of high demand, Uisce Éireann is introducing targeted nighttime restrictions to protect daytime supply for homes and businesses.
Targeted overnight restrictions will take place from 10.30pm until 6.30am in the following catchment regions: Knocklong , Ballyagran, Coolcappagh, Castlemahon Newcastle and Dromcollogher.
Uisce Éireann will continue to monitor water levels closely in Limerick and adjust operations daily based on demand, usage and weather conditions.
In addition, to support water supplies during this period of increased demand, Uisce Éireann has also put contingency measures in place across East and West Limerick. These measures include targeted contingency tankering operations to replenish treated water reservoirs and support areas experiencing increased demand. The additional water helps maintain reservoir levels, protect local supplies and strengthen network resilience, ensuring a reliable water supply for customers during periods of sustained pressure on the system
Tankering to treated water reservoirs will continue from tonight to the following locations – Bruff, Doon (Lacka), Cappamore-Foileen, Coolcappagh and Newcastlewest. All contingency arrangements including nighttime restrictions will remain under continuous review, with a further operational assessment scheduled for Monday, 20 July.
Brian Harrington, Operations Manager, Uisce Éireann urged the community in Limerick to support the conservation measures. “Nighttime restrictions are being implemented to support treated reservoir recovery and maintain daytime supply. Conserving water will help protect resources and maintain supply for all. When there is an increase in temperatures it leads to a rise in demand for water. Water is a hugely precious resource, and it is important to conserve water.”
Simple steps taken at home, in the garden and at work can make a real difference in protecting supply during this time.

Tips to Conserve Water
· Drop the hose: Use a rose-head watering can over a hose or sprinkler. Aim for the roots. Water plants early or late in the day to limit evaporation.
· Take short showers instead of a bath: Reducing your shower time can save up to 10 litres of water per minute. A typical bath uses 80 litres
· Turn off the tap: Not running water while brushing your teeth or shaving can save up to 6 litres a minute. Keep a jug of water in the fridge for drinks.
· Fill up your appliances: Only run your washing machine and dishwasher when they have a full load.
· Fix dripping taps: A single dripping tap can waste between 5,000 and 10,000 litres of water a year.
· Use a basin in the sink: Use a basin when rinsing vegetables or washing dishes and reuse that water for your plants .
· Clean the car with a sponge: When washing your car, avoid the hose and use a bucket and sponge instead.
· Install a water butt: Use it to collect rainwater from your gutters for gardening or washing the yard.
· Pick plants wisely: Opt for low-water plants like lavender or olive trees. Established plants and lawns often don't need watering unless there's a drought
· Lock in moisture: Add bark or plant material to flower beds to prevent evaporation or use gel beads in pots to keep roots hydrated.
