Across supply region :
Spring heatwave 2026

The situation

Exceptionally high temperatures have, as expected, created very high demand for tap water supplies.

We had planned for very high demand given the weather forecasts by increasing output at our water treatment works across our supply area and putting extra water into the network.

What have we been doing?

Our fleet of tankers has been working 24/7 putting additional water into the network in areas where demand has been extremely high and to support our stored water reservoirs.

However, due to the nature of water supply networks, some customers on higher ground or at the far end of the network may have had low pressure or supply interruptions, especially at peak use times.

In addition we have had some leaks and bursts, which while frustrating, is normal for a network of more than 9,000 kilometres in length and under high pressure at all times. Again, our teams have been working tirelessly to fix these.

In areas where there has been supply interruption - or where we believe issues may occur - we proactively delivered bottled water to our vulnerable customers on our Priority Services Register.

Looking ahead

Forecasts show the hot spell is set to continue, so we are asking customers to be mindful of their water use, to help relieve pressure on the water system.

We are sorry to customers who have had interruptions or low pressure in their water supply and know how frustrating it is, especially in very hot weather.

We will continue to do all we can to prevent and resolve the issues.
