Abstract

This study analysed the quality of rainwater on different roofing systems for domestic use in Kubwa, Abuja, Nigeria. The study compared harvested rainwater quality of three (3) roof types, corrugated iron roofing (Zinc), Aluminium roofing and Asbestos roofing systems. The result shows that most of the physiochemical characteristics of rainwater were generally within the WHO threshold considered safe for domestic water use. However, some of the parameters such as iron, lead and cadmium were above the WHO standard for drinking water. Corrugated iron roofing system yielded a high concentration in iron, lead and cadmium. Asbestos roofing system yielded a higher concentration of iron and lead. Aluminium roofing system also yielded a high concentration of iron and lead. The results of the three (30 roofing systems showed that rainwater does not meet the required standard of WHO for drinking. The study therefore recommended that harvested rainwater in the stiudy area should not be used for the purpose of drinking as it is likely to pose danger to the health of mankind but could be used for other domestic uses.
