Drought restrictions


During periods of abnormally low rainfall there may be a drought.

It doesn't happen often: it's been more than 40 years since we had to impose restrictions on water use such as a hosepipe ban.

We take our responsibility to maintain and manage the resilience of our water resources seriously and adopt a measure to ensure future resilience.

It identifies the percentage of the population that is at risk of severe supply restrictions in the event of a drought happening once every 200 years (equivalent to a 0.5% chance each year).
