Rainwater Harvesting: Quick Guide

Rainwater Harvesting

Collecting rainwater is an easy way to save water, support your garden, and reduce runoff. Here’s how to get started.

1. Pick Your Collection Surface

  • Roofs work best because they are large and easy to access
  • Keep gutters clear of leaves and debris
  • Make sure downspouts slope toward your collection point

2. Choose Your Storage

  • Rain Barrels – 50-100 gallons, ideal for gardens. Must have tight lids, overflow spigot, and opaque material to prevent algae
  • Cisterns – For larger needs, above-ground (plastic, concrete, metal) or underground (concrete, polyethylene). Requires more space and sometimes professional installation

3. Filter and Divert

  • Gutter Screens – Keep leaves and twigs out
  • Downspout Diverters – Direct water to your barrel or cistern
  • Inlet Screens – Prevent smaller debris and insects; clean regularly

4. Access Your Water

  • Spigots/Outlets – Connect hoses or fill watering cans
  • Optional Pumps – Boost water pressure for sprinklers
  • Overflow Management – Direct excess water safely away from your home

5. Maintain & Stay Safe

  • Clean gutters, downspouts, and containers regularly
  • Screen openings to prevent mosquitoes; a small vegetable oil layer can help
  • Drain barrels in freezing weather
  • Keep containers stable with lids secured

Ways to Use Rainwater

  • Garden & landscape watering
  • Outdoor Cleaning(cars, patios, furniture)
  • Compost moisture
  • Livestock or pet water (with filtration)
  • Toilet flushing in advanced systems
  • Emergency water supply

Benefits

  • Reduces soil erosion and runoff
  • Provides a drought-ready water reserve
  • Naturally nourishes plants

Rainwater harvesting is a simple, eco-friendly way to conserve water and keep your plants thriving. Whether you start with a single barrel or a larger system, each drop you collect helps your home, your garden, and the environment.
