The water and sanitation sector is critical to Nigeria’s human development, providing access to safe water and sanitation services. The sector is dominated by public utilities, but there are opportunities for investment in private water and sanitation services, water treatment, and wastewater management. Opportunities for investment in the sector include water infrastructure development, sanitation solutions, and water conservation technology. Nigeria’s water and sanitation trade value is relatively low, but there is potential for growth in the domestic market. Shared value in this sector includes improved health outcomes, job creation, and sustainable development. Competitive advantage in this sector includes a large and growing population, a need for improved water and sanitation services and infrastructure, and a supportive regulatory environment.
