People in some areas around Norwich are facing a summer of disruption, but the pay-off for the pain is that their homes will at reduced risk of flooding.

More than 100 properties in and around Norwich were left under water in summer 2014, as flash floods hit communities.

Norfolk County Council said the problems were caused by an ageing drainage network that was nearing the end of its useful life.

A bid for £9.1m from the Department for Transport to tackle the issue was successful and the county council is adding £1.2m to make improvements in Costessey, Hellesdon, Old Catton, Sprowston and Thorpe St Andrew

The first £1m is to be spent in Sprowston, with work due to begin tomorrow. It will continue until September and will mean roads have to be closed.

A spokesman for Norfolk County Council said: 'In most urban areas the drainage system is made up of gullies positioned regularly on the highway which connect into small scale pipe networks that discharge to existing water courses.

'In many residential areas on the northern fringes of Norwich the existing gullies do not work this way. The existing gullies discharge into soakaways and boreholes which connect to underground aquifers.

'These systems are old and no longer work effectively, which can lead to flooding during prolonged or heavy rainstorms.'

In Sprowston, a large network of new carrier pipes will be laid in trenches, linked to the existing soak-aways and boreholes.

Excavated areas will be fenced off and roads closed, with diversions.

The council apologised for any inconvenience which will be caused.
