Description
Nigeria is currently facing various environmental challenges such as water scarcity
and water quality; which is one of the largest environmental problems. However, the available
supply of renewable water is short of the demand in Nigeria. Researchers have studied many
alternative to better solve the emerging water supply problem. This study considers rainwater
harvesting as an alternative source of water to ameliorate the possible scarcity. To better
understand common practises in the rain water harvesting community and motivation for
collecting harvested rainwater a socio-demographic survey was conducted in four communities
in Ado-Odo/Ota Local Government Ogun State Nigeria to determine the rate of water
consumption and supply from current water sources. A total of 400 questionnaires were
administered to various household and the data collected through the survey were analysed using
SPSS and selected statistical methods. Rainfall data for Ota was obtained and it was to calculate
the cumulative runoff in a year was determined for roof sizes are ≤ 75m2.This study
demonstrated among other things that rainwater harvesting has the potential of contributing
significantly to solving the problems of water shortage suffered not only by the rural-poor
communities but also in the urban areas where conventional modes of water supply have failed
to provide the desired level of service.
