Rainwater Harvesting
Rainwater Harvesting
Rainwater harvesting is a series of methods designed to collect and store rainwater for future use. However, the execution of such systems is not always as simple as it may seem.
The success of rainwater harvesting depends heavily on factors such as the amount and intensity of rainfall in a particular area. The catchment area and type of surface used for collection can usually be tailored to suit household needs. While rainwater collection can serve as an additional water source, it is important to note that rainfall distribution is often uneven throughout the year.

Sources of Rainwater Collection
There are two main sources for collecting rainwater: rooftop collection and surface runoff. Of the two, rooftop collection is the most commonly used due to its ease of implementation. In apartment complexes, a combination of both methods ensures maximum water collection.
Here’s how the system works at City Borewells and the components involved:
Catchment Area
The catchment is any surface where rainwater falls, such as rooftops or the ground. To prevent debris from entering the system, we use a coarse mesh to filter out larger particles.
Conduits
Conduits are the drains or pipelines that transport rainwater from the catchment area to the harvesting system. These are typically made from materials like PVC or GI (Galvanized Iron).
Filter
A filter is used to remove suspended pollutants from the rainwater. It consists of a chamber filled with filtering media such as fiber, coarse sand, and gravel to clean the water before it enters the storage tank or recharge structure. For enhanced filtration, we also include charcoal in our systems.
Sump
The sump is the storage unit where filtered rainwater is collected. It ensures that the rainwater stored is free from pollutants, keeping it safe for future use.
