💡 Tips for Optimal Rainwater Harvesting

Storage Sizing: Aim for 2-4 weeks of water supply to handle dry periods.

First Flush: Divert the first 2-5mm of rainfall to remove contaminants.

Filtration: Use mesh filters and consider additional treatment for potable use.

Maintenance: Clean gutters and storage tanks regularly to maintain water quality.

Overflow: Design overflow systems to handle excess water during heavy rainfall.
