Managing water resources

Our current water resources

Rainfall has been lower than average this winter but at this stage our reservoirs are full and we have no concerns about water resources.

July 2018

Despite June and July being the driest on record in Cambridge, replenishment from rainfall in January through to April has resulted in normal groundwater levels for this time of year.

The prolonged hot weather has seen increased demands for water, however, there are no concerns for water resources in our area of supply.

We encourage customers to use water wisely at all times, particularly in the garden during this exceptionally dry period.


Our water comes from underground sources reliant on being replenished over the usually wetter winter periods. Very low rainfall in 2017 meant groundwater recharge and water levels were lower than we would normally expect for the time of year. However, a single dry winter doesn’t give us immediate cause for concern. Following late Spring recharge due above long-term average rainfall from January to April 2018, groundwater has been replenished and are now at normal levels.

We continually monitor the water resources situation and work closely with the Environment Agency, other water companies and large water users, to ensure we can manage our resources effectively in periods of below-normal rainfall.  We also have a Drought Management Plan in place detailing the triggers for any actions we may need to take during extended dry periods to manage both demand and supply of water to our customers.

The Cambridge Water area of supply is in a dry region of the UK with lower annual rainfall than Barcelona. We always do what we can to conserve supplies and encourage our customers to be as water efficient as possible by offering advice, free water saving devices and the option of free water meters to be fitted where possible. We particularly ask them to think about water efficiency during the summer periods when they typically spend more time in the garden and enjoy outdoor leisure activities using water.
