Are you up for the challenge? 

On average, a person uses 143 litres of water a day - could you save 5 litres a day?

We love our water and we want you to continue to enjoy using it but we need your help to keep the network flowing for everyone. Demand is higher than normal, overall our reservoirs are looking healthy but there's only so much water we can treat and pump to your homes, businesses and hospitals. 

We can’t do it alone. We need everyone to play their part – small changes in water use make a big difference when multiplied by our 1.8 million customers. If every one of our customers saved 5 litres of tap water a day, that would save nearly 10 million litres. From quicker showers, changes in flushing habits to being smarter with water in the garden - whatever your lifestyle there’s lots of  simple things you can do to save water.

Our top tips for saving water


Saving water couldn’t be easier.


In the garden:

  • Use a water butt to collect rainwater – it could fill up with water for free 300 times a year
  • Use a watering can to get water where your plants really need it – at their roots and not on foliage
  • It’s best to water plants early in the morning, or in the evening, when it will take longer for it to evaporate
  • Mulch around plants using organic matter such as wood chip or compost. Use stones, gravel or sea shells as a mulch to dress plants in pots. Mulching is marvellous: it deters weeds, improves soil texture and helps soil retain water
  • During dry spells, focus watering on young plants as they establish, vegetable crops and plants growing in pots
  • Place a stick or other marker where you have planted rambling or trailing plants – that way you know you are watering their roots
  • If there is a dry spell, your lawn will not look as lush but it will recover when it rains again. If it needs mowing, set your lawnmower to cut higher and leave clippings where they fall to act as mulch
  • Spending more time in the garden lets you get to know it well – which parts dry out first, which areas hold on to water, what is in shade and when.

In the home:

  • Turn off the tap while brushing your teeth
  • Keep a jug of water in the fridge so you don’t have to run your tap cold
  • Use a bowl for washing up / rinsing fruit and veg – then use this water for plants   
  • Have a shower instead of a bath
  • Only use your dishwasher or washing machine when you have a full load (this will save money on your energy bills too)
  • Only fill the kettle with as much water as you need (this will save energy too)
  • Fix leaking taps and toilets


What are you doing to save water?

It's rained all winter so why are you asking us to save water?


Spring this year was the sunniest since records began, and May was the driest. Our reservoirs filled up over the wet winter and we currently have plenty of raw water stored.

With the recent warm, dry weather coupled with people spending more time at home and in the garden we're seeing demand for tap water rocketing. Even though we aren’t welcoming visitors to our region at the moment, we are still treating and pumping as much tap water through the network as we were at this time in 2018 and 2019.

Demand is exceptionally high, there’s only so much tap water we can pump through the network which is why we need your help to reduce demand so we can keep the taps running in your homes, hospitals and schools.
