Yorkshire water invests £3.4m in improvements to Brough and North Ferriby

Work is taking place across East Yorkshire this summer as Yorkshire Water invests £3.4m to improve and upgrade storm overflows in Brough and North Ferriby, as it continues to improve water quality in the Humber.

The two projects, which will reduce discharges to the river Humber, are part of a wider £180m investment across Yorkshire to reduce the frequency and duration of discharges from storm overflows into the region’s watercourses.

Contract partners, Peter Duffy Limited (PDL) started on site in June with a £900k improvement scheme at Brough Combined Sewer Overflow (CSO).  The upgrades include diverting the existing incoming sewer from the adjacent Humberside Enterprise Park to a new wet well.

New valves, replacement valves and consumption chamber will be installed on the existing rising main and outfall as well as replacement non-return valves.  A new auto storm return pump has been integrated to ensure wastewater is returned to the network for full treatment.

Work is also underway at Ferriby High Road CSO, North Ferriby to complete a £2.5m improvement, to create a new below ground sewage pumping station with additional 88m³ storage.  

Work includes the installation of new pipework, manholes, and a new rising main.  The investment at both overflows in East Yorkshire will help improve water quality in the Humber.

Lumi Ajayi, project manager, Yorkshire Water, said: “This work is part of £180m investment by Yorkshire Water to improve watercourses and water quality by reducing storm discharges across the county by April 2025.

“These important upgrades to the storm overflows at Brough and North Ferriby will prevent infiltration from the Humber and reduce storm discharges and overflows into the estuary during periods of prolonged or heavy rainfall.”
