Why are there still hosepipe bans when it's been raining so much?

Three water companies in England - South East, South West, and Yorkshire - still have "temporary use bans" in place. Thames Water recently lifted restrictions after levels improved across Greater London, but 10 out of 14 areas in England are still in drought.

Heavy rain throughout November may have left some wondering why hosepipe bans are still in place in parts of the country.

Three water companies - South East, South West, and Yorkshire - still have "temporary use bans" restricting the amount families and businesses can use.

Thames, Southern and Welsh Water recently lifted restrictions they imposed in the summer after supplies improved, but the National Drought Group has warned that 10 of 14 areas in England still have official drought status.

What are the water companies saying?

South East Water said its current hosepipe ban will remain in place "for the foreseeable future".

This is because water levels at reservoirs and aquifers are "much lower than normal after the dry, hot summer", its head of water resources Lee Dance said.

He added: "Although we are receiving some much-welcome rain in the South East, we will continue to monitor rainfall through the winter and evaluate whether changes can be made."

South West Water only has bans in areas where water levels are "especially low".

It said recent rainfall has helped river and reservoir levels "slowly start to recover".

But supplies remain reduced throughout the region, with Colliford Reservoir in Cornwall only at 24% capacity and Roadford Reservoir in Devon at 43%.

Yorkshire Water strikes a more hopeful tone, saying: "Reservoir levels are moving in the right direction.

"We're seeing some significant increases week on week as the rainfall, drought permits, additional leakage activity and support from our customers to save water, help them to top up."

But it added that "rain doesn't always fall evenly across the whole region" and that South Yorkshire in particular still has low-level reservoir levels.

Why isn't the recent rain doing enough?

With temperatures exceeding 40C (104.5F) this summer, 2022 has been the driest year on record since 1976.

Water companies had to increase their water supply by 40% in some areas - the equivalent of hundreds of millions of litres.

After drawing on those reserves, 10 of 14 areas in England are still in drought - despite it raining most days in November.

According to the Met Office, by November, the UK would usually expect to have seen 88% of average rainfall for the whole year.

But the country as a whole is currently falling well short of that - at 76% or 879mm of rain.

And England and Wales have seen even less - at 70% (605.8mm) and 68% (1001.2mm) respectively.

Scotland and Northern Ireland are doing slightly better at 82% and 83%.

A Met Office spokesperson described current rainfall levels as "still well below average".

They added that although it has "boosted totals slightly… it hasn't been enough to bring them back to average for the whole year".

Environment Agency executive director and chairman of the National Drought Group John Leyland warns: "We cannot rely on the weather alone - if we are to avoid a worse drought next year, it will require action by us all."

Why are some regions struggling more than others?

Different regions get their water from different sources.

In England and Wales, two thirds of the water in our taps comes from reservoirs, rivers and lakes, (surface water).

Scotland and Northern Ireland use almost exclusively surface water because they
