Abstract:
Today, water supply is a critical issue in developing countries. Collecting rainwater from the roofs of buildings in urban areas for unsanitary and irrigation purposes is possible and help resolve the water crisis of citizens. If roof pond surface system of houses are modeled and simulated according to local daily precipitation statistics, percent of the water needs of residents,, the area of rainwater harvesting, running costs of the system and are designed and performed based on results obtained from charts and graphs, it causes increase the efficiency of these types of systems in urban areas.
In this study, rain pond surface System and the performance of tanks for storing rainwater and the daily water needs of the residents in the buildings in Rasht is analyzed based on daily precipitation statistics from 1338 to 1386. According to these results, it can be said that if the volume of tanks and daily unsanitary needs of residents are calculated based on the physical and hydrological condition of the building, Rainwater storage in tanks reaches the maximum and there are more days for providing unsanitary needs of the residents by collecting rainwater. In Rasht, 80% and 50% of all days of the year, the daily unsanitary needs of determined residents can be provide by using large and small tanks respectively. |
