The large water supply project is the first project financed by China Exim Bank in Nigeria, and it is also a concrete practice that helps China-Nigeria pragmatic cooperation constantly reach a new height. The main content of the project is to build a pipe network with a water supply capacity of 480,000 cubic meters/day. After the completion of the project, Nigeria's capital region will get rid of the embarrassing situation of no pipe network after water supply from the water plant, open up the last "kilometer" of the water supply system, and effectively alleviate the shortage of water supply for 1.6 million people.
