Rainfall and Resources

 

April 2018

Groundwater levels: Below average

Bough Beech Reservoir: Above average

Water companies 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. The previous winter (2016-17) was cold and grey but quite dry with only two thirds of average rainfall across our supply area. This meant that groundwater sources were a lot lower than normal going into last winter and we therefore needed a minimum of 80% of the long-term average rainfall to ensure enough water would be available to meet the spring and summer demand. October – the start of the critical six month ‘recharge season’ - was dry, with only 35 per cent of average rainfall during the month, followed by only half of the expected rain in November. However, December through to the end of March was a lot wetter, bringing the total winter rainfall to 94% of the long-term average, meaning that temporary usage restrictions this year are now looking highly unlikely.

85 per cent of the water we supply to our customers comes from underground and levels are still below average for this time of year which is why our water efficiency activities and messages are relevant all year round to remind people that water is a precious resource, whatever the weather. 

We have a wealth of tips and information on our website, as well as tools to help customers reduce their bill and free water saving devices: http://www.waterplc.com/pages/home/saving-water/
