Salford is set to undergo a groundbreaking £525 million wastewater reset, marking a significant milestone in the city's environmental transformation. This ambitious project aims to revolutionize wastewater management, enhance resilience, and minimize environmental impact over the next five years. At the forefront of this initiative are two flagship treatment works upgrades, each with its own unique plan and purpose.
Salford's Two-Phase Wastewater Treatment Works Plan:
Salford's wastewater treatment plant is in for a substantial upgrade, with an investment of £225 million. The key focus is to introduce a new process that will significantly reduce ammonia and phosphorus levels before treated water is discharged into the Manchester Ship Canal. However, this upgrade comes with a challenge: the limited space available for development in Salford. To make way for construction, five existing trickling filters will need to be demolished, creating a complex two-phase construction process.
Phase one will take place on the contaminated land area, providing sufficient process capacity to release some of the existing trickling filter beds for construction. Once operational, this phase will lay the groundwork for the second phase, ensuring a seamless transition to the new system.
Eccles' Massive £302 Million Investment:
In contrast, the Eccles wastewater treatment works is set to receive an even more substantial investment of £302 million. The plans include the construction of a massive 60,000m3 underground storage tank, equivalent to 24 Olympic-sized swimming pools, along with a new pumping station, screening plant, and odour control systems. The demolition of the existing north bank of six trickling filters is necessary to free up land for these new assets.
The additional storage capacity will play a crucial role in alleviating pressure on the network during heavy rainfall, significantly reducing spills into Salteye Brook and the Manchester Ship Canal. This project is a testament to the ongoing efforts to improve water quality and environmental performance in the region.
The Broader Context: United Utilities' Big North West Upgrade:
Salford's wastewater reset is just one piece of the puzzle within United Utilities' ambitious £13 billion Big North West Upgrade. This comprehensive plan aims to drive new infrastructure, replace aging water mains, and cut leakage to record lows. By 2030, it will reduce storm overflows by 60% while protecting over 500km of rivers and bathing waters. The Salford program is a vital component of this larger initiative, contributing to the overall goal of enhancing water quality and environmental sustainability in the North West.
