Assessment of Wet Precipitation and Harvested Rainwater and Different Types
of Roof Materials in Urban Area
Author(s): G P Shivashankara*
The study is an assessment of the quality of wet precipitation and the harvested rainwater samples from different types of roof catchments such as reinforced cement concrete (RCC), galvanized iron, asbestos cement & galvalume sheets in urban area consisting of residential, commercial, downstream of industrial area with Bengaluru urban area. The precipitation samples were collected using wet precipitation collector by placing it on the terrace of the building. The harvested rainwater samples were collected in a staggered manner as first, second and third flush from all the roofs. The samples were analyzed for pH, TDS, conductivity, cations, anions and some heavy metals. Mean pH of wet precipitation was around 5.44 which are less than neutral pH 5.60, depicts slight acidic nature of wet precipitation. The study shows that lower pH in precipitation was controlled by acidic species of.. View More»
