Problems of Poor Drainage System

According to Cairn (1986) many low income communities in developing countries consider storm water drainage to be their most urgent need as far as urban infrastructure is concerned. This is partly because their houses are often built on unsuitable land. In areas sufficiently close to the city centre for journey for work to be

afford, or on which the owner’s will allow them to stay as squatter in land that is in suitable for other purpose. This is often on steep hill sides subject to erosion and landslides or it is law-lying, marshy land often subject to flooding.

Park (2007) stated that even in the arid areas where average rainfall is low tropical when it comes is more intense than in temperate than in the temperate climates, and the lack of vegetation and of adequate drainage means that torrents of water can form in minutes causing damage to homes and properties which will take years to repair, Rain-water is not tile only problem. Leaking water mains, waste water from washing and bathing and the sewage from overflowing septic tanks and blocked sewers constitute health hazards, damage buildings and cause flooding if an adequate drainage system does not exist.
