|50 gallons||21″ diameter x 3′ height|
|75 gallons||24″ diameter x 4′ height|
|100 gallons||28″ diameter x 4′ height|
Keep in mind that larger rain barrels can capture and store more water, but will also require more space and may be more difficult to transport and install. Consider these factors when selecting the best size and capacity for your rain barrel.
Site Selection and Preparation
Before you start building your rain barrel, it is essential to choose an appropriate site and prepare the area for installation.
Consider the following factors when selecting the location for your rain barrel:
- Proximity to downspouts: Your rain barrel should be near the downspout of your gutter system to effectively capture rainwater.
- Accessibility: Ensure the chosen spot is easily accessible for maintenance and water distribution purposes.
- Ground slope: It is best to place the rain barrel on a flat surface or an area with minimal slope to ensure stability and prevent tipping over.
- Sun exposure: A shady area is preferable to limit algae growth and prevent the water from becoming too hot during the summer months.
A stable and level foundation is crucial for the proper installation and function of your rain barrel. Here are some steps to prepare the foundation:
- Measure the area: First, measure the dimensions of your rain barrel and ensure there is enough space for it.
- Clear the area: Remove any debris, grass, or stones within the area, so you have a clean surface to work with.
- Level the ground: Flatten the ground as evenly as possible using a shovel or tamping tool. This will ensure stability and reduce stress on the rain barrel when it is full.
- Add a base material: Once the ground is level, add a base material such as gravel or concrete pavers to provide additional support and improve drainage.
By selecting an ideal location and preparing a stable foundation, you can ensure the proper installation and the long-term success of your rain barrel.
Building the Rain Barrel
Now we will focus on assembling the various components of your rain barrel for maximum water conservation.
Creating the Inlet
First, let’s create the inlet for water to enter the barrel. Find the top center of your barrel and drill a hole that matches the size of your downspout. Then, use a wire mesh or screen to cover this hole and prevent debris from entering. Secure the mesh with a clamp or rubber gasket to ensure a firm attachment.
Building the Overflow System
An overflow system helps redirect excess water once the barrel is full. Start by drilling a hole near the top of your barrel, preferably on the opposite side of the inlet. Attach a PVC elbow fitting and a short piece of PVC pipe to the hole, sealing any gaps to prevent leakage. Ensure that the overflow pipe directs water away from your home or towards another water conservation system.
Attaching the Spigot
Now it’s time to attach the spigot at the bottom of the barrel for easy water access. Drill a hole a few inches above the barrel’s base, making sure it matches the spigot size. Use thread seal tape to wrap the spigot threads and insert it into the hole. Secure the spigot with washers and tighten the associated nuts to prevent leakage.
Securing the Lid
Finally, secure the barrel’s lid to discourage children or animals from playing in or around the barrel. Place the lid onto the barrel and use strong bungee cords or rope to hold it firmly in place. Make sure the lid is sturdy to prevent accidents.
Connecting the Rain Barrel to Your Downspout
Before connecting your rain barrel to the downspout, ensure that the barrel is level and secure on a solid base. Now, follow these steps to connect the barrel to the downspout:
- Measure and cut the downspout: Measure the height from the ground to the top of the rain barrel’s inlet. Mark this height on your downspout, and use a hacksaw to carefully cut the downspout. Remove any sharp edges using a file or sandpaper.
- Attach flexible downspout adapter: Place a flexible downspout adapter over the end of the cut downspout. Make sure it fits snugly and secure it with a metal band or a zip tie if needed.
- Connect adapter to the rain barrel: Position the rain barrel under the flexible adapter, ensuring the adapter is placed directly over the barrel’s inlet. Cut the adapter, if necessary, to achieve a proper fit. Keep the overflow hole or hose directed away from your home’s foundation.
- Secure the connection: Once you’ve connected the adapter to the rain barrel’s inlet, ensure that both the adapter and the barrel are stable and secure. You can use straps or brackets to attach the barrel to a wall for added stability.
With the rain barrel connected to your downspout, you’re ready to start collecting water for your garden, lawn, or other outdoor needs. Make sure to regularly check the connections and stability of your rain barrel, especially during heavy rainstorms.
Maintenance and Care
Regular maintenance is essential to keep your rain barrel functioning efficiently and preventing issues such as mold, algae growth, and bad odors. Follow these steps to ensure proper care of your rain barrel:
- Inspect for leaks: Periodically check your rain barrel for any leaks. Small leaks can be sealed using waterproof caulk or silicone sealant. For larger leaks, you may need professional assistance.
- Clean the filter: The filter in your rain barrel should be cleaned every few months to avoid clogging. Gently remove any debris and rinse the filter under running water. Replace the filter if it’s worn out or damaged.
- Treat for algae and mosquitoes: Add a few drops of non-toxic, liquid mosquito repellent and a couple of capfuls of household bleach to the rain barrel water. This will help prevent algae growth and mosquito infestation.
- Check the overflow: Ensure that the overflow system is unclogged and functioning correctly. This will prevent water damage to your property during heavy rains.
- Winterize your barrel: In colder climates, it’s essential to empty and store your rain barrel during winter to prevent freezing and damage. Disconnect the barrel from the downspout and open the spigot to let it air dry.
