NI Water is urging people across Northern Ireland to reduce water use in their gardens as dry, warm weather persists and demand rises for drinking, cooking and washing.

The appeal comes as temperatures reached 26C in County Down on Tuesday, with similar highs expected through the rest of the week and into the weekend. No significant rain is forecast for at least seven days, adding to strain on supplies.

The utility is asking households to avoid using sprinklers and hosepipes, which consume large volumes quickly. Much of that water evaporates in hot conditions, NI Water said. Instead, people should use a watering can for plants that genuinely need moisture and leave established lawns unwatered.

Anna Killen, an education officer with NI Water, said that grass is resilient and will recover after dry spells. Lawns may turn brown but are simply resting, and they green up again once rain returns.

The company also advised residents to consider simple steps: only run washing machines and dishwashers when full, take showers instead of baths, and check homes for leaks. Collecting rainwater in water butts was recommended for garden use during drier periods.

In the Republic of Ireland, water utility Uisce Éireann has introduced nighttime restrictions on 13 supplies as a precautionary measure, mainly in parts of counties Kilkenny, Tipperary, Donegal, Cork and Meath. A statement said such restrictions are used only where needed to protect local supplies and reduce the risk of more serious disruption later.

With high temperatures continuing, NI Water said that curbing outdoor water use helps ensure there is enough for essential needs across communities.
