Introduction
Rain barrels are a simple yet effective way to collect rainwater for non-potable uses like watering gardens, lawns, and plants. By building and maintaining a rain barrel properly, you can conserve water, reduce utility bills, and support sustainable gardening during droughts while minimizing reliance on municipal water sources.
Securing the Foundation
Place your rain barrel on a flat, sturdy surface to support its weight. A full 55-gallon drum can weigh up to 450 pounds, so ensure the ground is level and the surface can handle the load. Consider using a base like concrete blocks or a wooden pallet to elevate the barrel and make it easier to access the spigot. Elevating the barrel also helps prevent water from freezing in cold weather and allows gravity to assist in water flow.
Installing a Screen Cover
Use a fine mesh screen to cover the top of the barrel. This prevents mosquito breeding and keeps debris like leaves and twigs from falling into the water. The screen should be tightly secured to prevent any gaps where insects can enter. Additionally, consider adding a leaf guard or a diverter to further reduce debris entering the barrel. These devices can be purchased or made from materials like plastic mesh or a simple funnel.
Adding a Spigot
Install a spigot near the bottom of the barrel for easy access to water. This allows you to connect a hose directly to the barrel or fill watering cans without spilling. Ensure the spigot is securely attached and sealed to prevent leaks. Consider adding a valve or a tap with a shut-off feature to control the water flow. This will help you manage the water usage more efficiently and prevent wastage.
Using Water Promptly
Utilize the collected water within a week or before the next storm to avoid stagnation. Stagnant water can breed mosquitoes and may become contaminated. Regularly emptying the barrel also helps prevent overflow and ensures you have space to collect more rainwater. If you have a large garden or multiple plants, consider setting up a drip irrigation system connected to your rain barrel. This will allow you to water your plants automatically and efficiently, reducing the need for manual watering.
Don’ts
- Drink or Use for Cooking/Bathing: Rainwater collected from rooftops may contain contaminants like bird droppings, dust, and other pollutants. It is not safe for drinking, cooking, or bathing. Use the collected water only for non-potable purposes like watering plants or washing outdoor items.
- Use Chemical-Treated Roofs: Avoid using rain barrels with roofs treated with moss killers or other chemicals. These substances can pollute the collected water. If you have a treated roof, clean it thoroughly before setting up your rain barrel to remove any residue.
- Store Barrels Outdoors in Winter: During winter months, avoid leaving rain barrels outdoors where snow accumulation and melting can introduce dirt and other contaminants. Store the barrels indoors or empty them before the first snowfall to prevent contamination. If you must leave them outside, ensure they are empty and clean before the next rainy season.
Summary
Building and maintaining a rain barrel is a practical way to conserve water and support sustainable gardening. By securing the foundation, installing a screen cover, adding a spigot, using water promptly, and avoiding drinking or using for cooking/bathing, you can effectively manage rainwater collection. Remember not to use chemical-treated roofs and store barrels indoors during winter to ensure clean and safe water usage.
