Rainfall and Resources

February 2018:

Groundwater levels: Below average

Bough Beech Reservoir: Above average
 

Following a dry autumn, we are hoping for more of the recent wetter weather to refill groundwater sources that have remained well below average for many months.

The wet end to last summer was welcomed but underground aquifers – rocks which act like a giant sponge – only usually fill up from rainfall during autumn and winter when there is less plant growth and evaporation. October to March is the critical ‘recharge period’ and autumn rainfall was very low - October was dry with only 35 per cent of long term average rainfall during the month, followed by only half of the expected rain in November. December and January were a lot wetter but average rainfall is still needed until the end of March to minimise the likelihood of water restrictions this year.

Like all water companies, we depend on winter rainfall for the water we supply to our customers. Last 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 this winter and now is the time they should be replenished. By this point in the year we would be expecting our sources to be at a higher level, ready to meet demand in the spring and summer. This is important as 85 per cent of the water we supply to our customers comes from underground.

We are working hard to manage the water we do have, from installing new pipelines to move water around our network, to finding and fixing leaks as quickly as possible. However, the weather is the one thing nobody can control 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 are asking customers to use water wisely. 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/
