Southern Water is lifting water restrictions in its Sussex and Kent water supply areas.
The temporary use ban that was brought in on April 5 following two exceptionally dry years will end tomorrow (Thursday June 14).
Anglian Water and Thames Water will lift their restrictions at the same time.
The introduction of restrictions, for the first time in five years, was quickly followed by downpours for the rest of April, which was the wettest on record.
This wet weather continued throughout most of May and into June and has helped boost water sources and importantly, keep down demand for water.
However, the exceptionally wet weather has resulted in severe flooding in parts of the region and Southern Water continues to focus on dealing with this.
The company’s four reservoirs are all more than 80 per cent full, some 35 per cent higher than they were at the start of March, and there has been some recharge of underground water supplies.
Some sources are still below average for this time of year but the majority are no longer in drought status.
Water Quality and Strategy Manager Meyrick Gough, said: “While our focus remains firmly on dealing with aftermath of the torrential rain and flooding in the south over the last few days it is also right for us to lift the water restrictions.
“Our supplies have been topped up by the wet weather and are now in a much stronger position going into the summer than they were when we introduced the restrictions in early April. However, with the underground sources, which supply the vast majority of our customers, still below average for this time of year, we are asking our customers to continue with their efforts to use water wisely and not waste water.
“We have seen a great response from customers and demand has dropped considerably as a result of the wet weather and customers doing their bit and we are very grateful for their continued support.”
Southern Water says it has reduced leakage across its region to its lowest ever level and continues its programme to replace 256km of water mains to help reduce the risk or bursts.
The company has now installed more than 200,000 water meters across Kent, Sussex and Hampshire which are equipped with leak alarms that will help to save five million litres of water per day.
This is part of the company’s metering programme, which will result in 93 per cent of customers being metered by 2015.
