Rainfall and resources

Rainfall and rivers are key to us being able to supply you with a high-quality supply of water.

Rainfall and resources

Groundwater levels – Significantly below average

Bough Beech Reservoir level – Below average

Like all water companies, we depend on winter rainfall for the water we supply to our customers as underground aquifers – rocks which act like a giant sponge – only usually fill up between October and March when there is less plant growth and evaporation.

Due to the prolonged dry weather, coupled with higher demand for water in these hotter summer days, our levels of raw water resources are less than we'd expect for this time of year.

While we are keeping our customers informed, and urging everyone to use water wisely, we will also keep the need for further measures, such as a restriction on the use of sprinklers and hosepipes, under close review for the rest of the summer period. The need for restrictions will depend on the rate of decline of our groundwater and reservoir sources, and the level of customer demand.

In the meantime, we are doing all that is necessary to manage our water resources to keep customers supplied and protect the environment, including working closely with government, regulators and other water companies, to minimise the need for any restrictions in the coming weeks and months.

Each person in our supply area uses around 150 litres of water a day at home – that’s 20 litres higher than the national average. Water is a precious resource whatever the weather and as 85 per cent of the water we supply to our customers comes from underground, our water efficiency activities and messages are relevant all year round. We have a wealth of tips and information on saving water, as well as tools to help customers reduce their bill and free water saving devices.

We are also doing our bit to ensure that there is enough water available for people's vital every day needs by:

  • Finding and fixing leaks as quickly as we can – including on customers’ pipes

  • Starting up additional water treatment works

  • Moving water around our pipe network to use more plentiful resources

  • Providing water saving visits for our customers
