Rainwater Harvesting

Rainwater harvesting is the process of collecting and storing rainwater that falls on roofs, surfaces, or catchment areas. This collected water can be used for various purposes like irrigation, landscape maintenance, domestic use, and even for replenishing groundwater.

1. Catchment surfaces: These are the areas where rain falls and from which water is collected. Roofs are the most common catchment surfaces in residential areas.

 2. Gutters and downspouts: These direct water from the catchment surface to storage tanks or reservoirs.

 3. Filtration system: Rainwater collected from roofs often contains debris, dirt, or contaminants. Filtration systems remove these impurities before storing the water.

 4. Storage tanks: These hold the collected rainwater for later use. Tanks can be above-ground or below-ground depending on space and requirements.

 5. Distribution system: Pipes or pumps distribute the stored water to where it's needed, whether for household use, irrigation, or other purposes.

 Benefits of rainwater harvesting include reducing demand on mains water supply, lowering water bills, and contributing to water conservation efforts. It's environmentally friendly and can also help mitigate flooding and erosion by reducing stormwater runoff.
