Yorkshire Water is progressing its £3.1 million investment in a major improvement scheme to upgrade and increase capacity at its Stamford Bridge wastewater treatment works.

Contract partners, M Group, are continuing the upgrade to the site, including the installation of a 257m³ storage tank to increase capacity.
The extra capacity will process additional wastewater flows following the opening of the new HMP Millsike, the Cat-C prison, adjacent to HMP Full Sutton.
Lucy Ram, project manager, Yorkshire Water, said:
“The build of the new 257m³ storage tank is required to cope with the 41% increase of the existing population based on both the inmates of the new prison facility, as well as the anticipated increase in annual holiday visitors to the area.
“This comprehensive upgrade is expected to complete by January 2026. The extra capacity will reduce the likelihood of storm overflows discharging into the river Derwent and help to improve water quality.”
The work is expected to cause minimal disruption to local residents and is part of Yorkshire Water’s largest ever environmental investment of £8.3bn over the next five years across the region.
Other examples of investments planned include along the coast and across east Yorkshire include:
- Replacement of more than 200km of water mains replacement over the next five years, including 54km in Hull and East Riding of Yorkshire in the next two years
- More than 150,000 smart meter exchanges across the region
- Over £140m investment to reduce storm overflows across the East Riding, including £60m at Bridlington wastewater treatment works over the next five years
- More than £2bn investment in the water industry national environment programme (WINEP) over the next five years
- £23m on improved monitoring of the wastewater network
- New investments at Scarborough, Robin Hood’s Bay and Bridlington to improve bathing water quality
