Water saving tips during hot weather

5th July 2018


The extended hot weather, lack of rain and increased demand for water recently means our reservoir levels are lower than should be at this time of year. As a result, United Utilities have imposed a hosepipe ban for those in the North West, .

To find out how the ban impacts you please visit United Utilities for more information.

The English summer has been kind to us in 2018 so far, with prolonged spells of warm weather and sunshine and temperatures as high as 31 degrees. However, the demand for water is much higher than usual during these hot spells and can have a significant impact on water supply and pressure demand. When water use is increased at the same time by many homes and businesses, it reduces the water pressure in the network. It’s important for businesses to be mindful of how to save water.

With the hot weather set to continue, here’s our best advice for using water wisely, without disrupting the day-to-day running of your business.

  1. During hot spells, water use is higher between 7am-11am and 4pm-11pm. For businesses that regularly use a high volume of water, adjusting times to refill tanks or to water areas of land to outside of these peak windows can significantly reduce demand.
  2. For businesses with large grassy areas, watering can be minimised to conserve supplies. Although it may brown, grass is surprisingly resilient and will soon return to green with the next rainfall.
  3. If watering is essential for business; using sprinklers set with a timer, drip feed irrigation systems or other water saving devices automated outside of peak demand windows can also help.
  4. Check for any repairs to pipework. Leaking taps, can waste hundreds of litres of water a day and if it’s a hot tap, this will also push up your energy bills by hundreds of pounds a year!
  5. Encourage employees to be mindful of water use – for example, fill a jug with tap water and place it in the fridge instead of running the tap until it turns cold to fill a glass of water.
  6. When washing dishes or laundry, only set dishwashers and washing machines to run when they are completely full to avoid water waste and need for repeated use.
  7. For countless industries, cleaning can account for up to 70% of your water usage. Review cleaning processes and make small changes to routines to make a big impact on the amount of water you conserve.


Keep an eye on the website of your local water company to check for any restrictions which may be put in place due to the hot weather – here are some useful links:
