Households across England and Wales will begin to receive legal notices within a fortnight telling them that water companies will soon be responsible for sewers beneath their properties – at an estimated cost to the industry of £4.2bn.
The companies – which will assume ownership of about 230,000km of private sewers, adding 74 per cent to the length of network they control – are to press the regulator for permission to pass the bill on to customers.
“If we spend a pound, we want a pound back,” said Tony Wray, chief executive of Severn Trent.
Industry insiders fear that, with much of the private sewer network crippled by chronic underinvestment, they remain in the dark about the true scale of the liabilities they are due to take on at the start of October. The ownership transfer of the sewers, whose total length would stretch around the equator almost six times, marks the biggest change in responsibility for sewerage services since the 1930s.
The forthcoming legal notices will come as a surprise to the many homeowners who are unaware that they are at present responsible for the maintenance of the pipe that connects their drain to the public sewer in the street.
But for others who have suffered from problems such as blocked drains – and the costly repairs that often follow – the mass ownership transfer will come as a welcome relief.
