A holistic framework for water sustainability and eduction in municipal green spaces

This paper describes an irrigation control system that incorporates wireless soil moisture sensors and real time user feedback. The system is deployed on a large scale in a municipal green space. It is estimated that between 60% to 70% of municipal water is used for irrigation. Current systems struggle to adapt to site specific variations. Our approach augments an existing commercial water budget controller with a wireless soil sensor network and an adaptive irrigation controller to significantly reduce water usage. The system requires less user intervention than today´s commercial systems that attempt to offer similar water savings. The community is able to watch dynamic changes in soil moisture and watering so that they can garner a better understanding of patterns of sustainable water use.
