MULTI TANK MODEL FOR ENERGY EFFICIENT RAIN WATER HARVESTING
| Abstract: Specifically, the study attempted to estimate the extent of the various components of price. The study was Rain Water Harvesting (RWH) to supplement service water is an important aspect of sustainable development. As such, much research has been carried out on optimizing the system components of RWH systems so that a maximum Water Saving Efficiency (WSE) can be reached with a minimum storage capacity, enabling the outlay on capital minimized. However, if the system is to be used in a multi-storey building, either the storage tank has to be placed near the roof at an elevated position, which would require structural reinforcements and would be disturbing the aesthetics of the building, or it has to be placed at ground level with a pumping arrangement to feed the service points at different floor levels. If the pumping option to be practiced, the energy utilization should be minimized to uphold the principles of sustainability. By introducing a multi tank model, where a smaller tank is installed for each floor at its roof level in addition to the main storage tank, a solution can be reached with superior system performance. In the model, the roof collection enters the top most storage tank first and then cascades through multiple tanks in multi-storey situations, before being collected in the main storage tank, vastly improving the overall energy efficiency of the system. The model, not only addresses the space and structural issues of the building but also ensures that the aesthetics of the building envelop is not disturbed due to smaller sizes of the upper tanks. By developing a system algorithm, the effective run-off and pumping requirements can be determined, which could be a significant design tool to analyze the performance of the model for energy efficient rainwater harvesting. |
