Cover Story: Rainwater harvesting (RWH) involves the diversion, capture, and storage of rainwater for later use. Incorporating a first-flush diverter in a RWH system can improve the water quality of harvested rainwater. This two-part paper evaluates the water quality of roof runoff from three roof types; quantifies first-flush diversion based on a mass removal of pollutants from both simulated and actual storms; evaluates first flush based on continuous conductivity measurements; and investigates the potential for long-term accumulation of polycyclic aromatic hydrocarbons (PAHs) in soils receiving harvested roof runoff with no first-flush diversion. Results indicate that current first flush diverters may be undersized if using mass removal as a design target, and using harvested rainwater from rooftops may potentially lead to accumulation of PAHs in soil when a first-flush diverter is not utilized. View this paper
