Work to prevent flooding in Thorpe St Andrew will begin next week, but the £1.1m project will mean five months of disruption.

Thorpe St Andrew has been badly affected by flooding in the past and Norfolk County Council was last year successful in a £9.1m bid to the Department for Transport for money to help solve that and other problems.

The council is adding £1.2m to that to tackle the issues.

In most urban areas the drainage system is made up of gullies on the highway connecting into small scale piped networks that discharge to existing water courses.

But in many residential areas on the northern fringes of Norwich the existing gullies do not work this way, instead discharging into soakaways and boreholes which connect to underground aquifers.

These older systems no longer work effectively which can lead to flooding during prolonged or heavy rainstorms.

The work in Thorpe St Andrew will see carrier pipes laid in trenches linking to existing soakaways, boreholes and drainage system.
