Drainage system is a system constructed for the
purpose of draining waste water from our homes and surrounding in other to
avoid accumulated waste water in our environment. It also helps to channel
storm or runoff water during raining season in other to avoid flooding and
presences of stagnant water. Park (2007)

Poverty has forced many to occupy areas prone to
floods and mud landslides in area which has no good drainage system. Due to
these, as observed in Caracas, Venezuela over half a million people lived in
the flood prone areas and so many lives and properties have been claimed by
this hazard.

In words of Mba (1996), poor planning as it has to do

forced to flow along the roads, gutters and overflow into depression where
seasonal lake develop which would ultimately flood with subsequent rain.

Examples of cities where houses are constructed
directly on drain channel to include Lagos, Calabar and Ibadan, and that this
practices has resulted into blockage of storm drains and consequently leading
