In-ground sprinklers. (Rain Bird / July 7, 2014)

An in-ground sprinkler system dispenses the exact amount of water your lawn or garden needs, when and where it needs it. The sprinklers are connected by hoses, and a controller directs valves to open and close much like a faucet turning on and off. A backflow valve prevents water in the garden hose from being sucked back into the water supply of the house. The system prevents damage from under- or overwatering, improves the health of the lawn or garden, and actually may lower your water bill by cutting down on waste. You can even water when you're not home by using the timer. And you'll never again have the drudgery of dragging a garden hose around the yard, which alone makes the installation a benefit.

An irrigation contractor will charge $2,013 to install an underground sprinkling system in a 2,000 square foot area, which includes labor and material. You can buy the components and install it yourself for $645, a savings of 68 percent. Sprinkler systems are sold at lawn and garden centers and online, where there's often help to plan and lay out the design. Check with your local building department about any requirements.
