United Utilities has completed a major £50 million project at its wastewater treatment works in Bury that will help improve water quality in the River Irwell.

The scheme has delivered two new storm tanks at the site, increasing the amount of storm water that can be stored during periods of heavy rainfall and helping to reduce the number of times storm overflows operate.
Together, the tanks can hold 6,000 cubic metres of storm water. Construction work began in May 2024 and was completed this summer.
The project is one of several investments being delivered by United Utilities across the Bury area to help reduce spills and improve water quality in the River Irwell and the surrounding catchment.
Emma Oakes, Wastewater Business Lead for Greater Manchester at United Utilities, said:
"This is a major investment for Bury and an important step in improving water quality in the River Irwell. By increasing the amount of storm water we can store during heavy rainfall, these new tanks will help reduce the need for storm overflows to operate and deliver lasting environmental benefits for the local area.
"This is just one of a number of projects we're delivering across Bury and Greater Manchester as we continue to invest in improving water quality right across the region.”
United Utilities is investing more than £13 billion to protect and enhance more than 500 kilometres of rivers, lakes and bathing waters, while safeguarding drinking water supplies for millions of customers across the North West.
Near-real-time microbial monitoring of wastewater discharge and bathing waters is now possible thanks to the BactoSense ID solution created by Swiss-based bNovate Technologies.
Craig Nienaber, Business Development Manager for Safe Access Solutions (SAS) at HUBER Technology, explores why the company is seeing a growing level of interest in its safe access solutions for critical infrastructure providers, including their application in wastewater treatment assets.
