I will not argue with you yes poor or no drainage na one of the main cause of flooding, but the kind flood we dey see for this country don pass this one of having good drainage, the one way occur 2012 and 2013 even if we get good drainage e no fit stop the flood from not affecting us but having a good drainage will also help reduce it in some areas of the country and also dredging of our Rivers can also help to reduce this flood and most of the places way water dey use comote they don carry houses build finish and also sandfilling of swampy areas.
