Implement modern central sewerage systems
Nigeria's rapid industrialization and urbanization have led to a range of environmental issues, including air, water, and land pollution. A major challenge is the lack of modern central sewerage systems, which has resulted in poor sanitation and water pollution. Implementing modern central sewerage systems is crucial to improving pollution in urban Nigeria.
Modern sewerage systems can be categorized into two types: domestic and industrial sewers, and storm sewers. Domestic and industrial sewers collect wastewater or sewage from communities, treat it, and then discharge it. Storm sewers, on the other hand, collect stormwater runoff and divert it to temporary basins or directly to streams or rivers.
In Nigeria, the proportion of households connected to sewage systems is very low, with none in cities like Ibadan and Onitsha, and only 2%-3% in Lagos and Kano. This has led to the haphazard disposal of waste in squatter, slum, and even metropolitan areas, contributing to water pollution and health risks.
To address this issue, Nigeria should prioritize the development and implementation of modern central sewerage systems. This includes investing in the necessary infrastructure, such as pipes, pumps, and wastewater treatment plants. The treatment of industrial wastewaters before discharge is crucial to preventing pollutants from entering freshwater sources. Additionally, providing separate networks for domestic and industrial waste and stormwater runoff can improve the efficiency of the system.
By implementing modern central sewerage systems, Nigeria can significantly improve its sanitation and reduce water pollution. This will not only benefit the environment but also the health and well-being of its citizens, reducing the risks associated with poor sanitation and polluted water.
