The Effect of Roof Material on the Quality of Harvested Rainwater
Project Summary
Rainwater harvesting is rapidly expanding in Texas and elsewhere. However, few systematic studies have been conducted on the effect of roofing materials on the quality of harvested rainwater. The main objective of the research is to assess the effect of different commonly used roofing materials on the chemical and biological quality of harvested rainwater and to recommend roofing materials that would be most suitable for rainwater harvesting applications.
