Stormwater and Sewer System

Such a high population generates a large amount of trash, which is choking the city’s drainage system. Coupled with perennial flooding from the rainy season, the area is plagued with property damage and loss of life. Flooding in the Odaw Basin has impacted the Korle Lagoon to create “one of the most polluted bodies of water on earth,” according to PBS. To mitigate these issues, the Ghanaian Parliament approved the Accra Sanitary Sewer and Storm Water Drainage Alleviation program, a design-build project developed and implemented by Conti Federal.

Conti Federal extensively coordinated with the U.S. Export-Import Bank to secure financing for this project and performed all the planning, feasibility studies, cost estimating, engineering, land surveying, and construction services. The team created a project-specific Environmental and Social Impact Assessment and Relocation Action Plan and conducted waste management studies to establish a legitimate waste disposal method. Conti Federal built relationships with the affected communities to determine stakeholder needs and employed local labor.

Finally, Conti Federal began dredging the Korle Lagoon to clear the bottleneck of refuse and silt. The team’s equipment was self-financed and shipped overseas to satisfy Unites States content requirements, performing the full lifecycle of construction services.

Key features of the project included:

• Design-build
• Project development
• Budgeting and financing
• Feasibility studies
• Community outreach
• Environmental and social impact assessment
• Resettlement action plan
• Engineering design
• Construction services
