dc.description.abstractAbstract Rainwater harvesting is one of the viable ways of supplementing the surface and underground scarce water resources in areas where existing water supply system is inadequate to meet demand as being one of the potent measures for reducing impact of climate change on water supplies. The aim of this study was to estimate the rainwater harvesting potential of a typical house roof top in Ilorin Township for the purpose of supplementing household water needs. Ilorin has a mean annual rainfall of 1,244 mm which makes rainwater harvesting ideal. Intra annual variability lies between 0.04 and 0.4. Annually 590 m3 of rainwater can be harvested per household. Estimated annual water demand for flushing and laundry were 18, 24.12 m3, respectively. Harvested rainwater in Ilorin can meet household monthly water demand for toilet flushing and laundry except for December. The excess rainwater stored in September and October is enough to supplement the short fall in the dry months provided there is adequate storage. Water savings potential is highest in June and September which is the two-rainfall peak period in Nigeria. Keywords: Water demand, house rooftop, household, rainfall, runoff, rainwater
