Abstract |
The objectives of this study ware to evaluate the characteristics of rainwater from the paving areas for reusing it. Water samples were collected from two parking areas in K university for eight months (2001. 10 - 2002. 5) to estimate water quality with time. The characteristics of rainfall, run-off rainwater and stored rainwater were compared. The turbidity, pH, electro conductivity of rainfall were analyzed according to intensity and duration. The turbidity, pH, SS, color, oil, quantity of sand, BOD, and COD of run-off rainwater and stored rainwater were investigated. The results showed that pH was 4.13-6.59(rainfall), 7.6 0-8.60(run-off rainwater), and 6.7-8.2(stored rainwater). Also the turbidity of rainwater, run-off rainwater and stored rainwater were 1.25-12.8, 8.0-200 and 5.2-99.6 NTU, respectively. |
