Landscape irrigation is estimated to be the single-largest component of municipal water use in Texas. Municipal water demand, in turn, is the second-largest category of water use in the state, second only to agriculture. Texas communities aiming to use water supplies efficiently, therefore, need to take a hard look at the lawn. For this reason and as part of a greater effort to enable a resilient water future for Texas, the Texas Living Waters Project has performed an analysis of how each water provider in North Texas is approaching outdoor water use. We ask if communities are limiting the number of days per week that customers can water their lawns or simply limiting the number of hours per day automatic irrigation systems can be operated? We then examine both how much water can be saved through outdoor irrigation management and how much water we need to save to meet the region’s future water needs.
