The document discusses ETwater, a company that provides landscape irrigation management technology. It describes how ETwater systems work by collecting local weather data, calculating daily watering needs based on evapotranspiration rates, and communicating schedules to smart controllers. The system can reduce water use by 20-40% while improving plant health. A case study shows a Denver campus reduced its water consumption by 37% and water bill by 64% after installing ETwater controllers. The document also outlines barriers to adoption and incentives for using smart irrigation technologies.

- 7. EvapoTranspiration (the ET in ETwater) • ET is the loss of water from the earth & plants to the atmosphere – Evaporation from ground – Transpiration from plants • ET changes as weather changes • Different plants have different ET © 2012 ETwater Systems, Proprietary and Confidential – Not for Distribution 7
