An extra £1m will be spent by to tackle flooding problems at Yarmouth, Anglian Water announced today.

The investment - in addition to £850,000 already committed to deal with flooding problems in the area - is to be used to survey and clean sewers in the north of the town of sand that was washed into them during autumn floods and is causing blockages.

Anglian Water said to would build an extra 100 metres of sewer at Beccles Road where flooding also occurred. Other works planned include replacing sewers along Caister road, and renovating sewers at Southtown.

Andrew Mackintosh, spokesman for Anglian, said: ““It's a major underground system and it takes major money to sort it out.”

He added: “Yarmouth is effectively a concrete bowl. Every drop of rain that falls has to be pumped.”

He said Anglian Water had been in talks with ministers to work out how much new investment was needed to upgrade ageing sewers amid fears that global warming could make storms more frequent.

The works announced today are in addition to those announced last year to spend £850,000 on improving Garrison Road pumping house to increase capacity so that it can pump storm waters more quickly into the river. And a £20,000 computer model is being created of Northgate Street, where the worst flooding happened. The model will mean engineers can work out what would happen in times of heavy rain to work out how to solve the flooding problem.
