Combining investment and quality


The last stage of a £1 million scheme to improve water quality of the River Tees starts in Teesdale this week.

Northumbrian Water has already upgraded and screened nine combined sewer overflows in Barnard Castle, Eggleston, Middleton in Teesdale and Cotherstone. 

Combined sewer overflows are consented by the Environment Agency to discharge wastewater into water courses in times of very heavy rainfall, to protect properties and land from flooding.

The tenth combined sewer overflow will be constructed in land between The Lendings sewage pumping station and Thorngate Bridge and will take up to three months to complete.

Steve Gray, project manager for the scheme, said:  “I would like to thank customers for their patience while we have carried out this work and would like to reassure them that we will continue to do everything to keep disruption to a minimum.  We appreciate that work on this scale does cause disruption. 

“Protecting and enhancing the environment is at the core of what we do and between 2005 and 2010 we will invest £85 million to upgrade and screen 481 combined sewer overflows across the region.”

Construction traffic will access work sites and the compound, which is located in Barnard Castle sewage treatment works.  Temporary traffic management will be in place on the B6277 and it will be necessary to close a section of the footpath between the B6277 and the Thorngate Bridge.

Northumbrian Water is to carry out further improvement work, which is to begin in January 2010, to replace the temporary sewer pipe which is currently on Thorngate Bridge.  Residents will be notified about the work in writing.
