Buying Guide: How to Choose Rainwater Collection

How to Choose a Rain Barrel

A 1,000 square foot roof can collect 600 gallons from just one inch of rain. Rainwater collection captures this free resource for gardens, reducing water bills and municipal water demand.

Basic System Components

Rain Barrel: The storage container. 50-65 gallons is typical residential.
Downspout Diverter: Connects gutter to barrel, allows overflow to normal drainage.
Spigot: Dispenses water. Higher spigot maintains pressure; lower drains completely.
Screen: Keeps debris, leaves, and mosquitoes out.

### Capacity Considerations

50 gallons: Single garden bed, container plants
100-150 gallons: Multiple beds, small vegetable garden
250+ gallons: Serious gardens, dry climate, or water independence goals

Barrels can link together—start small, expand as needed.

### Placement Requirements

Position below downspouts, on stable level ground. Raised platforms (cinder blocks, stands) provide gravity pressure for hose use. Consider aesthetics—decorative barrels exist for visible locations.

### Legality Check

Rainwater collection is legal in most US states but regulated in some (Colorado recently legalized it). Check local laws before installing. Some municipalities offer rebates.

### Water Use Reality

Rainwater is perfect for:
Garden irrigation
- Container plants
- Lawn watering
- Washing cars
- Livestock

Not recommended without treatment:
- Drinking
- Indoor use
- Food-contact surfaces

Frequently Asked Questions About Rainwater Collection

How do I prevent mosquitoes in my rain barrel?

Screens are the first defense—cover all openings with fine mesh. Mosquito dunks (Bti bacteria) kill larvae without harming plants or animals. Keep water moving if possible. Empty barrels every 10 days during mosquito season if standing.

What happens when my rain barrel overflows?

Install an overflow hose directing water away from your foundation—either to your garden, another barrel, or back into the gutter system. Without proper overflow, heavy rains can cause foundation issues from pooled water.

Can I use rain barrel water for vegetables?

Generally yes for watering soil (not leaves). Roof runoff may contain bird droppings, asphalt particles, or debris. Avoid edible parts of plants for root vegetables. Many gardeners use rainwater for all vegetables without issues—just don't drink it.

How do I winterize my rain barrel?

Empty completely before freezing weather—expanding ice cracks barrels. Disconnect downspout diverter and return to normal drainage. Store barrel upside down or indoors if possible. Replace seals that may have dried over winter.
