Dŵr Cymru has said that it is "ramping up its operations" to accommodate the extra demands for water that it is anticipating across some parts of the country over the summer holidays.
The company has confirmed that demand for water has soared to near record levels over the past 72 hours, with prolonged high temperatures.
Yesterday the Met Office issued its first ever 'extreme heat' weather warning for large parts of the country.
Dŵr Cymru usually treats and supplies about 800 million litres of clean water a day to its three million customers— roughly the same amount needed to fill 320 Olympic-sized swimming pools. Over the last 3 days, the company says that it has had to supply an additional 15 million litres of water per day.
Dŵr Cymru predicts that this demand will continue with a 10% increase in demand expected between now and the end of September, which could increase by as much as 20% depending on weather and tourist numbers.
As a result, the company says that it has "ramped up production" at its water treatment works so that they are producing enough clean water to keep up with the demand.
Regional work is also taking place to prepare "popular tourism areas" such as Sir Benfro, Gwynedd, and Ceredigion for the influx of visitors.
Dŵr Cymru has advised that people should do the following things to help conserve water:
Don’t leave the tap running while washing hands or brushing teeth.
Take a shower instead of a bath.
Wait until the washing machine and dishwasher are full before putting them on.
Don’t fill the paddling pool to the top – and when you’ve finished, use the water on the plants in the garden.
Don’t use a sprinkler on the lawn to keep it green – the colour will soon come back once it rains.

Businesses are also being asked to make an extra effort not to waste water, particularly caravan parks, golf courses and farms.
