Effect of Roofing Material on the Quality of Harvested Rainwater
Due to the catchment surface, water absorption of the roof and the runoff coefficient of the roof, different roof styles can influence the quality and quantity of rainwater. Six roof models with different roofing materials (i.e., concrete tiles, color bond steel, bituminous, corrugated galvanized, vegetated and gravel) were installed in a field. In order to obtain the parameter value of water quality and rainwater quantity and roof efficiency, physical and chemical tests were performed. Measuring pH, turbidity, total suspended solid (TSS), total dissolved solid (TDS), temperature and metal testing are part of the laboratory work (Aluminium, Zinc, Lead, Copper). The findings obtained were compared to the water quality requirements set out in the National Drinking Water Quality Standards of Malaysia. It was found that the green roof (vegetated) are highly effective at volume reduction of rainwater. The average runoff coefficient for vegetated roofing is 0.349. For green roof materials, the relation between rainfall depth and runoff coefficient is not directly proportional. The green roof is ideal for the high yield of the rainwater field, although it is dependent on quantity assessment. The study reveals that the green roof materials perform in terms of heat reflector, but further treatment is required to achieve the high efficiency of rainwater storage quantity.
