• Catchment Area: The roof of a house or building, acting as a collection surface.
• Gutter and Downpipe: Channeling rainwater from the roof to a storage tank
• Filter: Removes debris and impurities from the water before storage.
• Storage Tank: A container to hold the collected rainwater.
• Pump (Optional): Used to distribute water to different points of use.

Process:

1. Collection: Rainwater falls on the roof and is collected by the gutters and downpipes.
2. Filtering: The water passes through a filter to remove leaves, dirt, and other debris.
3. Storage: Clean water is stored in the tank for later use.
4. Distribution (Optional): A pump can be used to distribute water to taps, toilets, or irrigation systems.

• Uses of Harvested Rainwater:
• Non-potable uses:
  • Toilet flushing
  • Laundry
  • Watering plants and gardens
  • Car washing
• Potable uses (after treatment):
  • Drinking water (in areas with limited clean water sources)
  • Cooking

Benefits of Rainwater Harvesting:

• Water conservation: Reduces reliance on municipal water supplies.
• Reduced water bills: Lower water usage can lead to cost savings.
• Groundwater recharge: Some systems can be designed to recharge groundwater.
• Reduced stormwater runoff: Helps prevent flooding and erosion.
• Improved water quality: Harvested rainwater is often cleaner than municipal water.
