Frequently Asked Questions

What is rainwater harvesting, and how does it work?

Rainwater harvesting is the process of collecting and storing rainwater from rooftops for reuse. Water flows from gutters through a filtration system, removing debris before entering a storage tank. The collected water is then used for irrigation, cleaning, livestock watering, and even toilet flushing in homes and businesses.

What are the benefits of rainwater harvesting?

  • Reduces reliance on mains water – Lowers utility bills and water consumption.
  • Eco-friendly – Supports sustainability and reduces water waste.
  • Cost-effective for businesses & farms – Helps cut operational costs.
  • Ideal for irrigation & livestock – Ensures a dependable water supply in dry seasons.

What size rainwater harvesting tank do I need?

The tank size depends on your water usage and roof size. Common options include:

  • 5,000L, 10,000L, 15,000L & 30,000L tanks – Popular for domestic & small commercial use.
  • Larger tanks up to 768,000L – Ideal for industrial & agricultural applications.
