Location & Overview
The Washwood Heath site, located in the heart of Birmingham, is set to become the primary depot and control center for the High Speed Two (HS2) project. Spanning 34Ha of what was once an industrial hub, this development is expected to usher in 550 new employment opportunities.

Challenge
As HS2’s most expansive brownfield site, Washwood Heath faced a considerable hurdle of 1,450,000m3 of cut/fill needing value engineering. The challenge was to find sustainable and cost-effective solutions to prevent around 135,000m3 of material from ending up in landfills or being incinerated, while keeping project timelines and stakeholder interests in focus.

Achievements

Historical Significance
Tracing back to the early 1900s, Washwood Heath was a bastion of British manufacturing. It hosted companies like the Wolseley Motor Car Company, Leyland DAF Vans, UK Mail, Alstom Works, and the CEMEX and Hanson plant. Yet, by 2009, this vibrant site stood still, grappling with soil and groundwater contamination. Today, with these issues addressed, HS2 is rejuvenating the site, restoring its regional prominence.

Treatment Strategy
Jackson Remediation incorporated HydroEater™ into their treatment approach. HydroEater™, our leading bioremediation product, is known for its unparalleled capability to break down hydrocarbon contaminants, often showing peak performance results up to 70,000 ppm. This powerful tool allowed for a significantly expedited site restoration, shortening the project timelines considerably. Moreover, its adaptability across various temperature ranges made it an ideal choice for this project. The economic benefits of HydroEater™ also cannot be overlooked, as its potent formula meant fewer applications were needed, translating to cost savings. This incorporation into the remediation strategy streamlined the process, ensuring both an environmentally conscious and cost-effective solution.

Validation and Outcomes
Post-treatment, all soils underwent rigorous testing, and clearance reports were produced. The previously projected 35,888 lorry movements were significantly reduced, resulting in a commendable saving of 856,498 kgCO2e.

Safety Protocols
The entire process adhered to the safety norms set by Duo and BBV. Regular safety briefings and inspections ensured compliance and stakeholder satisfaction.
