Storage tanks from rainwater harvesting systems (RWHs) are designed to provide flow equalization between rainfall and water demand. The minimum storage capacity required take into account the maximum variations of stored volumes, i.e., active storage, depends basically on magnitude variability profiles size Given random nature variables involved in hydrological process, probability theory is a ...

For countries with an abundance of rain, there is definite potential to implement a rainwater harvesting system for different applications. This paper describes feasibility studies open-pond ablution purposes, analysing the quality harvested and formulating model suitable performance measures. The formulated can be used analyse in any locality by inputting local meteorological data. Quality ana...

A regional-level and dimensionless analysis for designing a domestic rainwater harvesting system (DRWHS) was developed. To consider various combinations of water demand, storage capacity, effective roof area, and rainfall in DRWHS design, two dimensionless ratios were used, namely, demand fraction and storage fraction, along with a relationship between the two ratios. Firstly, Northern Taiwan w...

Water is a basic need for human activities, especially daily needs. Currently, there are still households on the coast of North Jakarta that rely non-piped water as source clean water; even with toddlers unfit sources due to economic conditions. It difficult access and expensive water, so they use groundwater, which detrimental environment causes land subsidence, or buys unaffordable water. Cou...
