Work on a £3m scheme to protect dozens of homes on the outskirts of Durham from flooding will start in January.
The third phase of work by Northumbrian Water in Belmont and Carrville will start on 6 January and is expected to take a year to complete.
It will involve installing more than 1,000m of sewer pipe and building storm water storage tanks.
There will be some road closures and other traffic management measures during the work.
A session to give residents more information about the scheme is being held on Wednesday at Broomside Communal Hall, Belmont.
