From harvesting rainwater in a rain barrel to composting your kitchen and yard waste in a compost bin, you can greatly increase your self-reliance by undertaking a few simple DIY projects.
The following is an excerpt from DIY Projects for the Self-Sufficient Homeowner by Betsy Matheson (Creative Publishing International, 2011). This handy book is your first step toward participating in the fast-growing self-sufficiency movement. Even if you live on a small urban lot, you can take steps to gain a little more control over things you consume using the plans in this book. This excerpt is from Chapter 1, “Collecting Rainwater.”
Practically everything around your house that requires water loves the natural goodness that’s provided with soft rainwater. When you know how to make a rain barrel, you can begin harvesting rainwater to irrigate your garden or lawn, water your houseplants, or top off swimming pools and hot tubs. A ready supply of rainwater is also a reliable stand-by for emergency use if your primary water supply is interrupted.
Collecting rainwater runoff in rain barrels can save thousands of gallons of tap water each year. A typical 40-by- 40-foot roof is capable of collecting 1,000 gallons of water from only one inch of rain. A large rainwater collection system that squeezes every drop from your roof can provide most — or sometimes all — of the water used throughout the home, if it’s combined with large cisterns, pumps, and purification processing.
Sprinkling your lawn and garden can consume as much as 40 percent of the total household water use during the growing season. A simple rain barrel system that limits collected water to outdoor (nonpotable) use only, like the rain barrels described on the following pages, can have a big impact on the self-sufficiency of your home, helping you save on utility expenses and reducing the energy used to process and purify water for your lawn and garden. Some communities now offer subsidies for rain barrel use, offering free or reduced-price barrels and downspout connection kits. Check with your local water authority for more information. Get smart with your water usage, and take advantage of the abundant supply from above.
Rain barrels, either built from scratch or purchased as a kit, are a great way to irrigate a lawn or garden without running up your utilities bill. The most common systems include one or more rain barrels (40 to 80 gallons) positioned below gutter downspouts to collect water runoff from the roof. A hose or drip irrigation line can be connected to spigot valves at the bottom of the rain barrel. You can use a single barrel, or connect several rain barrels in series to collect and dispense even more rainwater.
Plastic rain barrel kits are available for purchase at many home centers for around $100. If kit prices aren’t for you, a rain barrel is easy to make yourself for a fraction of the price. The most important component to your homemade barrel is the drum you choose.
Practically any large waterproof container can be used to make a rain barrel. One easily obtained candidate is a trash can, preferably plastic, with a snap-on lid. A standard 32-gallon can will work for a rain barrel, but if you can find a 44-gallon can choose it instead. Although wood barrels are becoming more scarce, you can still get them from wineries. A used 55-gallon barrel can be obtained free or for a small charge from a bulk food supplier. Most 55-gallon barrels today are plastic, but some metal barrels are still floating around. Whatever the material, make sure the barrel did not contain any chemical or compound that could be harmful to plants, animals, or humans. If you don’t know what was in it, don’t use it. Choose a barrel made out of opaque material that lets as little light through as possible, reducing the risk of algae growth.
A barrelful of water is an appealing breeding ground for mosquitoes and a perfect incubator for algae. Filters and screens over the barrel opening should prevent insect infestation, but for added protection against mosquitoes add one tablespoon of vegetable oil to the water in the barrel. This coats the top surface of the stored water and deprives the larvae of oxygen.
Tools and Materials
Whether you purchase a rain barrel or make your own from scratch or a kit, how well it meets your needs will depend on where you put it and how it is set up (see Image Gallery). Some rain barrels are temporary holding tanks that store water runoff just long enough to direct it into your yard through a hose and drip irrigation head. Other rain barrels are more of a reservoir that supplies water on-demand by filling up watering cans or buckets. If you plan to use the spigot as the primary means for dispensing water, you’ll want to position the rain barrel well off the ground for easy access (raising your rain barrel has no effect on water pressure).
In addition to height, other issues surrounding the placement of your rain barrel (or rain barrels) include the need to provide a good base, orientation of the spigot and overflow, the position relative to your downspouts, and how to link more than one rain barrel together. Tip: Wherever possible, locate your rain barrel in a shaded area. Sunlight encourages algae growth, especially in barrels that are partially translucent.
