As the driest period of the year approaches, Irish Water has said some of its supplies are already coming under pressure.

Regional Operations Manager John O'Donoghue said there has not been much rain since Christmas and already the utility is tankering water to some users and is concerned about pressure on supplies in parts of the country.

He said they want to stress the importance of conserving water all year round but especially coming into the summer.

In an effort to reduce water wastage, the company has launched a new online Conservation Calculator to allow water consumers better understand how they are using water and how wastage can be avoided.

The calculator, accessible at the Irish Water website, asks users a series of 15 questions to ascertain if there is wastage within the household.

Questions include whether or not taps or toilets are leaking, if water is left running during teeth brushing, if dishwashers and washing machines are filled to capacity before being turned on, and if members of the household are taking excessively long showers.

Based on the answers the online tool may suggest ways to save hundreds or even thousands of litres of water per week.

The Conservation Calculator was launched by Irish Water with the assistance of the pupils of Scoil Treasa Naofa in Dublin 8, a school that has been recognised for its own water conservation work.

Pupils made numerous suggestions on how to conserve water.

Seven-year-old Cali Atkinson said kettles do not need to be filled to the top. "Don't fill the kettle up all the way because that wastes water and you won't be using all of it and when you brush your teeth don't leave the water on."

Abdullah Bilal, 11, said fast fashion consumes vast amounts of water and should be avoided.

He also said water can be saved if plants are watered sensibly. "Water your plants in the evening as the water won't evaporate in the sun."

Eve McLean, 11, said people do not realise it is easy to waste water. "It's better to take three minute showers, less time in the shower because it's wasting water."

Speaking at the launch, Mr O'Donoghue said the Conservation Calculator will help every household save water.

"We've developed this system to show householders how they use water and to show tips on how they can save water as well. Water is a very precious commodity and we are challenged at certain times of the year in terms of saving water."

Research carried out for Irish Water shows 53% of householders admit to wasting water while 80% say it is important to conserve it.

Irish Water produces 1.7 billion litres of drinking water everyday, which travels through a network of 63,000km of pipes to users nationwide.

The company said the treatment process is complex with up to seven stages to make raw water suitable to drink.

The utility company is also working to reduce leakage from the network. At the end of last year, 38% of treated water was being lost through leakage, down from 46% in 2018.

Through continuing network repair and replacement, it hopes to reduce leakage to 32% by the end of 2024 and to 25% by 2030.
