Follow These Steps to keep rainwater from stagnating in a barrel


First, decide where you want to place the barrel. Make sure that the area is free of debris and other objects. If you plan on placing the barrel near an outdoor faucet, ensure that the pipe is not obstructed. It should be at least 2 inches away from any walls. Also, check with your manager if you live in an apartment building. Some buildings do not allow rain barrels inside.


After choosing a location, dig a hole for the barrel. The depth depends on the size of the barrel. For example, a standard 55-gallon drum measures approximately 46 inches deep. So, if you choose to use this barrel, you’ll need to dig a hole twice as big as the barrel itself. For example, if you buy a 55-gallon barrel, you’ll need a hole that’s 110 inches wide and 90 inches long.


After digging the hole:

  1. Pour in 4 to 6 inches of gravel.
  2. Add another layer of sand over the top of the gravel.
  3. Put down a piece of plywood.
  4. Cover the whole thing with soil.


Now comes the fun part. Place the barrel into the hole. Make sure that the opening is facing up. Also, ensure that the barrel’s bottom is level with the ground.


Next, fill the barrel with water. Use a hose to fill it until the water reaches the brim slowly. Don’t let the water overflow. Once the barrel is full, secure the lid using a strap.


Place the barrel somewhere in your yard. It should be placed close to a tree to get enough sunlight. However, if you don’t have access to trees, then you can place them anywhere. Just make sure that it doesn’t get too much sun.


The next step is to connect the barrel to a spigot. There are two options here. First, you can attach the fixture directly to the barrel. Second, you can drill holes through the side of the barrel and insert bolts. In both cases, ensure the barrel is securely connected to something. Otherwise, it could fall off while it rains.


Once everything is set up, wait for the rain. As soon as it rains, open the tap and fill the barrel. Then, wait for the water to stop flowing out of the spigot. When the flow stops, remove the cap and drain the excess water.


Repeat these steps every time it rains. Remember to empty the barrel when it’s dry. Also, remember to replace the cap after each use.


Once you’ve collected enough rainwater, you can store it in a bucket or tank. You can also use it to water plants.


Adding fish to your rain barrel helps keep the water clean and debris-free. If you live near a body of water, it’s worth considering adding some goldfish to your collection. These small tropical fish are easy to care for and make great pets.

They don’t require much maintenance and love to swim around and eat food. They’re quite fond of floating plastic rings found at pet stores. You can buy fish feeders online or easily build one yourself.
