What is a Rain Barrel?
A rain barrel is any above ground container modified to receive, store, and distribute rooftop runoff for non-drinking uses. The typical size of a rain barrel is 55 gallons. The main components of a rain barrel are a connection to the downspout, a filter to prevent mosquitoes from entering, a faucet to allow for regulated usage, and an overflow pipe to divert the excess water.
What are the benefits of rain barrels?
How can the water collected be used?
The rainwater collected can be used to water lawns and gardens or wash cars and bicycles. Rainwater collected within the barrel is safe for plants because the typical minerals and pollutants trapped in the rainwater are filtered out by plant roots. Rainwater collected in the rain barrel is not for drinking; rainwater is more acidic than tap water and may contain particulate matter from air pollution.
How much do they cost?
Rain barrels cost anywhere from $20 to $300. The fancier the rain barrel, the more the cost. Costs can be reduced if the barrel is installed by the homeowner. In the summer, lawn and garden watering account for 40% of average household water usage. By adding a rain barrel, the need for municipal water is reduced. According to the US Environmental Protection Agency, a rain barrel can potentially save most homeowners about 1,300 gallons of water during the peak summer months.
Are there different colors, designs, and types of rain barrels?
Rain barrels come in essentially any design or style. However, most regular rain barrels are usually black or blue plastic. Since only a ½ inch rainfall on a 160 square foot roof will fill a 55 gallon rain barrel, some people choose to get a tandem barrel (2 barrels at 1 downspout) or another barrel at a different downspout.
What type of maintenance is required?
The barrel will require periodic cleaning. A safe cleaning solution is 2 teaspoons of castile soap and 2 teaspoons of vinegar per gallon of water or 2 teaspoons of lemon juice per gallon of water. In the winter, the barrel will need to be emptied and disconnected from the downspout.

Step-By-Step Guide: How to Build a Rain Barrel
Obtain the Parts
- Food Grade Barrel
- Overflow (on side):
- 2 – 90° 1 ½" PVC pipe elbows
- 1 – 10 ft. 1 ½" PVC pipe sections (Only need 5 ft., but pipe is sold in 10 ft. sections)
- 1 –1 ½" PVC male threaded adaptor union
- Overflow alternative:
- 1 – 90° 1 ½" PVC pipe elbow
- 1 – 1 ½" PVC male threaded adaptor union
- 1 – 6 ft roll of 2" backwash hose
- 1 – 1 ½" 2" metal worm clamp
- Rainwater Entry (on top):
- 1 – 6" NDS green grate
- 1 – 6-7" metal worm clamp
- 1 – 12" square of aluminum window screen
- Spigot (on Front):
- 1 – ¾" brass spigot
- 2 – 12 oz. can of Krylon Fusion spray paint (or other spray paint with plastic bonding additive)
Drill the Holes
For the average rain barrel, you will need at least 3 holes:
- 1. Rainwater entry, on top of the barrel cut with an electric saw
- 2. Overflow, on side of the barrel, cut with a 1 7/8" hole saw
- 3. Spigot hole, on front, lower side of the barrel, cut with a 1" spade bit
Attach the Spigot
- Obtain the 0.75" brass spigot and screw into the drilled spigot hole. Once the barrel is painted, you may want to seal the threads with silicone sealant or teflon tape.
Assemble the Rainwater Entry Grate
- 1. Gather the parts
- 2. Fold the 12" window screen around the outside of the grate
- 3. Fit the metal clamp around the window screen and the grate.
- 4. With a partner, tighten the clamp with a screw driver
- 5. Set completed rainwater entry grate in top hole of the rain barrel
Assemble the Overflow
- 1. Find the PVC threaded adapter
- 2. Screw the PVC adapter into the overflow hole
- 3. Attach PVC Elbow. Attach a PVC coupling here if you are assembling the barrel to overflow into another rain barrel rather than the ground.
- 4. Fit 3' section of PVC pipe into elbow
- 5. Attach the second PVC elbow
- Spray paint for plastics should be added after the barrel has been washed and sanded
- To elevate the barrel for use, this picture displays 2 cement blocks
- The PVC pipe can be cut to different lengths depending on where the barrel is located, what's underneath of it, etc.
