A RETIRED train driver may just be the unluckiest man in Britain when it comes to getting billed for water he hasn't used.
Paul Hawkins goes to great lengths to conserve water, even re-using it wherever possible.
Yet his water supplier must think he is a serial-waster as he has twice been charged for using double the amount he actually got through.
What makes the situation even more bizarre is that he has been overcharged at two separate addresses.
Southern Water has billed Mr Hawkins for using an average of more than 200 litres a day at the two homes, based on water meters linked to his addresses, when he uses less than 100.
The 55-year-old said: "I live alone in an upstairs maisonette so I don't have a garden and I actively try and save as much water as I can.
"Whenever I do the washing up I pour the water into a bucket afterwards to mop the floor.
"Yet when Southern Water look at the reading for my address they must think I have several baths a day and run a water feature in my front room day and night."
In 2012 the Crawley News told how Mr Hawkins had been billed by Southern Water for using an average of 203 litres per day when living in Southbrook, Broadfield.
His neighbours were apparently only using 89 litres a day, despite having more people in their house and a garden.
At the time the water company apologised for the mix-up and assured Mr Hawkins that he would only pay for what he had used.
Much to his despair, the same thing has been happening since he moved to Callisto Close, in Bewbush, last July.
He explained: "I got my first letter through in September which said I was using an average of 257 litres of day. I instantly thought this is ridiculous and that it cannot be happening to me again.
"But because it was my first bill since moving in I gave them the benefit of the doubt in case there was a crossover period from the family that lived here before.
"I got my latest bill in March and the reading had gone up to 261 litres a day.
"After investigating the water meters under the driveway outside I found the serial number linked to my address wasn't moving when I ran the taps but one directly next to it was spinning like crazy."
A Southern Water engineer visited Mr Hawkins's home last Thursday and confirmed he was being charged for the water being used in another home.
A Southern Water spokeswoman said it was rare for meters to be mixed up, with only "about 1 per cent" of the 500,000 installed across the South East thought to be wrongly assigned.
Mr Hawkins is concerned, though, that there could be many more cases that residents just aren't aware of.
"Southern Water says it is very rare but for it to happen to me twice shows something must be wrong," he said. "My fear is that other people don't bother to check the amounts they are billed for and just pay it."
The Southern Water spokeswoman said that human error may have been to blame for the latest mix-up.
She added: "I can confirm that Mr Hawkins' meter had been wrongly assigned and for this we apologise.
"We have now updated his account, as well as his neighbour's, and they will now receive the correct bills. We will also refund any overpayments.
"We would like to reassure other residents of Callisto Close that we are checking all of our meter installations and, so far, have not found any more wrongly assigned meters."
