Water companies who rely on groundwater are unable to lift the hosepipe ban as the recent heavy rainfall, whilst boosting river and reservoir levels, has had "little impact" on the groundwater sources.
South East Water said groundwater provides 75% of their customers's water supplies, and levels remain severe:
All water companies must stick to their drought management plans which are agreed with our regulators. Just as those companies who are now in a position to withdraw their restrictions will be following theirs, so must we comply with ours and retain them.
Three of the UK's biggest water companies are lifting hosepipe bans, imposed to deal with drought, following weeks of heavy rain.
Hosepipe bans in place since April are to be lifted by three of the UK's biggest water companies.
