Risk of water restrictions remain in our supply area

 Last Update: 19 March 2018


Current levels: Below average

January and February may have seemed wet, but rainfall has been below average in our central supply area. However, we have started to see some recovery in our groundwater sources.

Due to this recovery, we will not need to implement restrictions as we come into the spring. However, this does not remove the possibility that restrictions will have to be introduced later on in the year. This will be dependent on the rainfall we receive in March as well as demand through the summer.

What we're doing to maintain a water supply

  • We are focused on fixing leaks, and achieved the highest leakage reduction target in the water industry. If you spot a leak you can report it here>>

  • We are investing in our network by replacing water mains to reduce the number of bursts and leaks.

  • Regular meetings with our Drought Management Group (DMG) in accordance with our Drought Management Plan (DMP)

  • Working in partnership with other water companies and the Environment Agency

  • Voluntarily taking less water from rivers where the levels are lower than usual.

  • We are continuing our water saving campaign for customers, ‘Keep track of the tap’ campaign to raise awareness and help people save water.


How can you help

On average, we use over 150 litres per person per day. Half of what we use is bathing, showering, and flushing the toilet. Here are a few tips to save water.

  • Shorten your shower – take a 4-minute shower, you’ll save around 50 litres (even cutting your shower time by 1 minute can save up to 15 litres)

  • Running your bath just an inch shorter than usual can save an average of 5 litres.

  • Turn off the tap while brushing your teeth, and save over 6,500 litres of water a year and encourage others to do the same

  • If you have a dual flush toilet, use the small button on your toilet for liquids)

  • A save a flush device in your toilet can save one litre per flush, saving up to 5,000 litres a year.
