How Much Water is Enough? Using PET to Develop Water Budgets for Residential Landscapes

Although conservation education programs typically suggest ways to reduce indoor and outdoor water use, information that can provide homeowners with a realistic estimate of the amount of water required to sustain their landscape at an acceptable quality is lacking.
