Water savings call as dry August hits reservoir levels

Scots are being urged to cut down the amount of water they use as reservoir levels across the country drop below normal levels.

A drier than average August means water levels in the east of the country are almost a quarter lower than they should be at this time of year.

Scottish Water is using tankers to supplement normal supplies in some areas and is looking at ways of pumping extra water into affected reservoirs.

The company said with no significant rainfall forecast for the rest of the month “it’s important that everyone helps”.

A similar call was made in May after Scotland experienced its driest spring in 70 years.

The current dry spell means:

• Average reservoir levels across Scotland are down 2% to 73%, which is 9% lower than the average of 82% for this time of year.
• In the east of Scotland, average reservoir levels are down 1% to 57%, which is 24% below the average of 81% for this time of year.

The prolonged spell of warm, dry weather has seen demand increase by 100m litres per day.

The new warning comes just a week after the Scottish Environment Protection Agency (Sepa) said a number of rivers and estuaries in the east of Scotland were approaching critical levels of water scarcity.

In the third such warning of 2025, the River Don and the Firth of Tay were among six areas described as experiencing “moderate” scarcity and quickly approaching “significant” scarcity.

Other rivers, including the Spey and Forth, are also being monitored.

The latest Scottish Water warning comes with suggestions on how people can help secure supplies. These are:

• Using water efficiently in the garden and outdoors spaces by using a watering can instead of a garden hose where possible and avoiding using sprinklers
• Taking shorter showers
• Turning the tap off when brushing teeth
• Using washing machines and dishwashers only when fully loaded
• Using a bucket and sponge rather than a hose to wash the car
• Checking for and repairing any leaking toilets

John Griffen, Scottish Water’s water operations general manager, said staff were “working hard to maintain normal supplies” for customers but needed people to be more efficient in their water use.

“We believe that a large part of the additional water use at the moment is in gardens so we would ask that customers are mindful of how much water they use there,” he said.

“Any rainfall we have had in parts of the country recently has not been prolonged enough to help our resources recover from the long spells of dry weather we have had recently and earlier this year.

“And, with no significant rain forecast for the next week or more, it’s important that everyone helps,” he added.
