The City of London is enhancing flood protection for the Greenway and Adelaide wastewater treatment plants, investing a combined $48 million. Greenway's project includes a 450-meter sheet pile wall and earth berm, constructed to combat floods up to one-in-250-year events.
Approximately 10,000 cubic meters of clay and 2,500 cubic meters of topsoil were utilized for Greenway, while Adelaide required 14,000 cubic meters of clay and 2,000 cubic meters of topsoil. Both projects commenced in 2024, with Greenway expected to complete in September 2024 and Adelaide in late 2027.
Federal funding covers 40% of the costs through the Disaster Mitigation and Adaptation Fund. Flood risks from the Thames River necessitate these upgrades, protecting over $1 billion in infrastructure. Challenges included managing community impacts and contractor efficiency across both sites, located only five kilometers apart.
