Allegiance Rainwater Harvesting (RWH) is a simple method by which rainfall is collected for future usage. The collected rainwater may be stored, utilised in different ways or directly used for recharge purposes. ... RWH An effective method in water scarce times, it is also an easily doable practice. Rainwater harvesting systems consists of the following components: Catchment- Used to collect and store the captured Rainwater. Conveyance system – It is used to transport the harvested water from the catchment to the recharge zone. Flush- It is used to flush out the first spell of rain. Filter – Used for filtering the collected Rainwater and remove pollutants. Tanks and the recharge structures: Used to store the filtered water which is ready to use. The process of rainwater harvesting involves the collection and the storage of rainwater with the help of artificially designed systems that run off naturally or man-made catchment areas like- the rooftop, compounds, rock surface, hill slopes, artificially repaired impervious or semi-pervious land surface. Several factors play a vital role in the amount of water harvested. Some of these factors are: The quantum of runoff Features of the catchments Impact on the environment Availability of the New technology The capacity of the storage tanks. Types of the roof, its slope and its materials The frequency, quantity and the quality of the rainfall The speed and ease with which the Rainwater penetrates through the subsoil to recharge the groundwater. Different types of RWH System: Recharge Well/ Recharge Pit Percolation well/ Percolation Pit Injection well Rain water Harvesting System Rooftop Rain water Harvesting Reservoir Collection & Reuse Recharge Tank Rooftop Rainwater Harvesting Filters First flues Filters Recharge Shaft Artificial Ground Water Recharge Recharge Tank Rainwater Storage tank Allegiance Water Management We are located in Gujarat - Ahmadabad, Vadodara, Surat.
