Outdoor Efficiency

In Cobb County we use about 60% more water in the spring and summer on outdoor uses.  In metro Atlanta the water used outdoors is especially valuable.  Due to our granite bedrock the outdoor water used for irrigation does not return to our water bodies for reuse.  Irrigation systems can use up to 50 gallons of water a minute. This can consume a lot of water and drive up water bills rapidly. It is important to have your irrigation system maintained by a certified irrigation professional.  There are simple ways to reduce your outdoor watering while still maintaining your landscape. 

Cobb County’s Water Efficiency Program offers information and resources to help you maintain your yard while saving water and money.  Cobb County offers a free outdoor water efficiency kit to help you monitor rainfall and soil moisture.  If you are interested in a free outdoor kit please contact the Water Efficiency Office.
