Rain Barrels



 


Why Rain Barrels?

Take an active role in recycling rainwater - install a rain barrel at your house!  A rain barrel is placed under a gutter's downspout next to a house to collect rain water from the roof.  The rain barrel holds about 50 gallons of water which can be used to water gardens and for other uses.  Harvesting rain water has many benefits including saving water, saving money on your bill, and preventing basement flooding.  By collecting rain water, homeowners are also helping to reduce flooding and pollution in local waterways.  When rain water runs off of hard surfaces like rooftops, driveways, roadways, parking lots, and compacted lawns, it carries with it pollution to our local waterways.  Harvesting the rain water in a rain barrel is just one of the ways homeowners can reduce rain water from running off their property and possibly causing pollution and flooding problems in local waterways.

Frequently Asked Questions (FAQs)

What do the rain barrels that are being provided in the "Build a Rain Barrel" workshops look like?

For Rutgers Cooperative Extension's "Build A Rain Barrel" workshops, 55-gallon recycled food grade barrels are retrofitted into rain barrels. See the following example:  


BlackRB

NOTE: Color of the barrel and spigot style may vary.


How do I install my rain barrel after I bring it home?


Follow the five steps outlined in the rain barrel brochure.

What if there's a heavy storm and my rain barrel overflows?

An overflow hose adapter is being installed in each rain barrel at the "Build a Rain Barrel" workshops.  The overflow hose adapter can attach to a garden hose so that when the rain barrel fills up, the overflow water can drain to a nearby garden or lawn area.  In addition to the overflow hose adapter, a manual or automatic diverter can be purchased and installed on the gutter to divert the rain water down the gutter like it would nornally do after the rain barrel has reached its capacity.

Where can I purchase a diverter for my downspout?

Various online store carry both manual and automatic downspout diverters.  The price range of a manual downspout diverter ranges between $15 to $40, and the price range of an automatic downspout diverter ranges between $20 to $50 and even higher.

What defense will my rain barrel have against mosquitoes?

You can purchase mosquito dunks, which are made from organic material that prevent mosquito larvae from forming. Another option would be to add a couple of tablespoons of vegetable cooking oil, which will not hurt your plants. The oil will float on the water's surface and suffocate the mosquito larvae. If that idea does not appeal, go to a nursery or garden supply store and see if they have ”summer horticulture oil."

Do not install your rain barrel without a garden hose. The open overflow hole will allow mosquitoes in.

Direct your garden hose to a garden area, lawn, or some distant runoff area away from the house.


My roof is small, is it even worth it for me to have a rain barrel?


Yes!  For an 800 square foot roof area that is being drained into one downspout gutter, 500 gallons of water will come off your roof in an one-inch rain storm.  If your entire neighborhood installs a rain barrel, it may have an impact on flooding and water pollution within your community.

Are there ways that I can decorate or disguise my rain barrel?  

Yes!  Lightly sand the exterior of the barrel with sandpaper to get rid of the waxy coat on the barrel to ensure that a paint primer has something to stick to.  After sanding, immediately spray the primer onto the barrel.  After the primer dries, you can paint the barrel.  If you want to hand draw designs to the barrel, acrylic-based paints work best. If you want to simply wish to change the color of the barrel, you can use Krylon (TM) Fusion Spray Paint for plastics or Rust-Oleum (TM) Plastic Primer that can be found at home centers and hardware stores.  After the paint dries, apply a coat or two of polyurethane to protect the paint.  You can also construct an enclosure for the rain barrel or hide it amongst your landscape to make it less noticeable.  A trellis with vine plants can be placed around your rain barrel to blend it within your landscape.

What can I do with the rain water that my rain barrel will harvest?

The water collected by your rain barrel could be used to water your flowers, shrubs, trees, and lawn.  You could use the water to rinse your hands/feet, landscape tools, or even your muddy shoes.  Please do not consume water collected in your rain barrel.

Is rain water good for plants?

Yes!  Natural rainwater has proven more beneficial for plantings and gardens than tap water because it doesn’t contain chlorine and its slightly acidic pH assists nutrient availability in most lawns and gardens.

Would it be safe to use the water harvested from my rain barrel to water vegetable gardens?

There is no definitive answer to this question.  It is best to avoid using the water from your rain barrel on plants grown for consumption until you receive results from taking a sample of water collected from your rain barrel and having it analyzed by your local water testing laboratory.  If you decide to have this water sample analyzed, have it analyzed for contaminants such as zinc, lead, chromium, arsenic, polyaromatic hydrocarbons, fecal coliform, and E. coli.  Once you confirm that the water is safe to use, it is best to use drip line irrigation to water the roots of the vegetables.  Be sure to thoroughly clean the vegetables with potable water before consumption.

What precautions should be taken for your rain barrel?

Always keep the lid to your barrel tightly secured to avoid any accidents involving children or animals.  Please do not consume water collected in your rain barrel.  

Can I leave my rain barrel out in the winter months?

Why is Katie sad? Look at the bottom of her barrel!


It is best to bring your rain barrel indoors during the winter months, whether it is a wooden barrel or a plastic barrel.  However, it is acceptable to leave your rain barrel outside for the winter as long as there is no water accumulating in the barrel. Simply turn the barrel upside down and/or cover the barrel.  


katie

"See what happens when you don't drain my barrel and then you leave it out all winter?
Frozen water in your barrel may cause the barrel to crack!
"

I have previously applied a moss killer on my roof, but I would like to collect water for my rain barrel.  What should I do?

Allow for a few (three or four) heavy rainfall events to occur before collecting water for use with the rain barrel.  To be cautious, flush the first batch of water collected with the rain barrel.  If you would like a written confirmation that the water is safe, take a sample of the water collected with the rain barrel to be analyzed at your local water testing laboratory.

Is there a rain barrel brochure that I can download?


Yes!  Feel free to download the rain barrel brochure by clicking here.

What else can I do to save water and prevent flooding and water pollution?

To save water, follow these tips:

  • Use mulch around your plants to reduce watering needs.
  • Install low-flow showerheads, faucet aerators, low-flow toilets, and other water saving devices at home.
  • Plant native plants that require less water and less fertilizer than exotic ornamental plants.

To prevent flooding and water pollution, follow these tips:

  • Redirect downspouts to areas where the water can soak into the ground.
  • Install a rain garden on your property to capture rain water before it goes into storm drains and into nearby waterways (see Rutgers Cooperative Extension's Rain Garden Fact Sheet)
  • Reduce the amount of hard surfaces on your property.  Use gravel, mulch, or pervious pavers to help infiltrate water into the ground.
What Rutgers Cooperative Extension programs does the Rain Barrel program fall under?

The Rutgers Cooperative Extension Rain Barrel program is part of the Stormwater Management in Your Backyard program and the Water Conservation Program for New Jersey.  

The Stormwater Mangement in Your Backyard program is a collaborative initiative between Rutgers Cooperative Extension Water Resources Program, the NJ Sea Grant Consortium, and the USDA CSREES Regional Water Coordination Program for the Northeast States and Caribbean Islands.

The Water Conservation Program for New Jersey is a collaborative initiative between Rutgers Cooperative Extenstion Water Resources Program and the New Jersey Department of Environmental Protection via funding from the U.S. Environmental Protection Agency.
