Landscaping
According to the City of Dallas water department, outdoor water usage can be more than 50% of our total summer water use.
Have you ever watched a sprinkler system water the sidewalk and driveway instead of the ground cover? That runoff is potential drinking water heading into the sewer system. By using a system of numerous and properly-placed sprinkler heads, programmed timers and sensors, and directed rain spouts, you can increase the amount of water that is directed to your lawn while reducing your water usage.
Water-efficient landscaping reduces both household water use and pollution that results from water runoff. The most efficient sprinklers throw large drops of water close to the ground. Misting sprinklers or sprinklers that throw water high into the air often allow the water to evaporate before it hits the ground. Make sure you use a sufficient number of sprinkler heads, so that the water is well distributed. More heads do not use more water, but when properly set actually conserve water with better distribution.
Soaker hoses are inexpensive, easy to install and ideal for planting beds. Drip irrigation applies water slowly to the soil directly surrounding plant roots.
Tip: Direct roof drains to lawns and gardens instead of the sidewalk or driveways. This allows some of the water to be absorbed by the landscape before running into the storm water system.
Irrigation systems are most effective when used in conjunction with a sensor-based watering system that prevents watering when it is not needed. Electronic control systems that are tied to satellite data can determine when and how much watering needs to occur, based on your local weather patterns. They can also be controlled through internet-ready control systems.
Where possible, use native plants that are drought hardy and adapted to the local environment. There are many beautiful plants, trees and shrubs that thrive in low-water environments and, once established, need very little supplemental water. For more information about local plants, contact your local agricultural extension.
