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 – 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.

Unlike the winters of 2017 and 2018, which were relatively dry, the winter of 2019 was one of the wettest on record. We saw above average rainfall which meant that our groundwater reserves rose significantly above average, putting us in a good place to meet the high demand of this summer.

Each person in our supply area uses around 160 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
  • Expanding our Home Water Efficiency Check programme
