Rainwater-collection systems are easy to set up


We've discussed collecting and storing rainwater before, but let's revisit the aspects involved for the benefit of those who are curious about the practice or are in serious need of options due to drought and water-rationing.

The setup can be as simple as a rain gutter, downspout and barrel. Kits are available from catalogs and the Internet, but you can easily make your own. Before getting started, however, check local building codes to be sure that it's OK to have rain-collection systems in your area.

First, to keep any debris from the roof from getting into your system, install a wire-mesh or plastic screen over the opening in the gutter where it is connected to the vertical downspout. Next, choose some kind of barrel or tank to collect the water. Many home-improvement stores and garden centers sell 55- to 75-gallon plastic barrels for around $50 to $100. Complete kits, including leaf screens and downspout connectors, go for $100 to $250. If you use a recycled barrel, select one that's been used for food storage rather than any kind of chemical.


If you're making your own system, install a heavy-duty plastic drain spigot into the barrel wall using waterproof plastic cement. Select one with common-size threads that can attach to a garden hose, and locate it as low as possible on the side of the barrel. Place the barrel on a raised platform to make room under the spigot for a watering can or hose attachment, and you're ready to water.


A rain garden is just a deep depression that collects runoff from impervious surfaces like roofs and driveways and lets it soak slowly into the ground. They're planted with shrubs and perennials and maintained like any other landscaped area of a yard.

Install a rain garden 10 feet from the foundation, about 30 feet from the downspout. Keep it away from low areas that always seem wet; they probably don't have the loamy or sandy soil that will percolate water properly. If you live in foothill areas, don't place a rain garden too close to a slope that can undermine soil stability. To test drainage, dig a 6-inch hole and fill it with water. If the water is still standing 24 hours later, choose another spot. Avoid septic systems and wells, too. They could become contaminated.
