Rain Water Collection

Why Collect Rainwater?

• Reduce your water bill and reliance on municipal supply
• Provide chemical-free water for gardens, lawns, and landscaping
• Help manage stormwater runoff and reduce erosion
• Promote sustainability and drought resilience
• Reduce demand on groundwater and reservoirs
• Emergency water supply for non-potable uses

How to Set Up a Rainwater Collection System

1. Choose a catchment area: Most commonly your roof. Clean, non-toxic roofing is best.
2. Install gutters and downspouts: Direct rainwater from the roof to your storage tank or barrel.
3. Add a first-flush diverter: This device discards the first flow of dirty water from the roof.
4. Use a screened inlet: Prevents leaves and debris from entering your tank.
5. Choose a storage tank: Food-grade barrels or cisterns are best. Size depends on your needs and rainfall.
6. Install an overflow outlet: Directs excess water away from your foundation.
7. Use a tap or pump: For easy access to your stored water.

Safety & Best Practices

• Use collected rainwater for irrigation, flushing toilets, washing vehicles, or cleaning (not for drinking unless properly filtered and treated).
• Keep your system clean and inspect regularly for debris, algae, or mosquito breeding.
• Label rainwater tanks clearly if not potable.
• Check local regulations—some areas have restrictions or incentives for rainwater harvesting.

Tips for Maximizing Collection

• Clean gutters and filters regularly for best water quality.
• Use dark or opaque tanks to reduce algae growth.
• Install a simple rain gauge to track your local rainfall.
• Direct overflow to a rain garden or permeable area.
• Consider connecting multiple barrels for more storage.
