At dawn we began taking apart the mechanical irrigation system on the first property.
While we preserved the anti-siphon vacuum breaker device that protects the potable water lines, the indexing valve was jettisoned for two electric valves, a water meter for data collection and the weather-based “smart” irrigation controller.
The day’s second property featured an irrigation system identical to the first, sans the back-flow device.
We removed the existing mechanical system for four electric valves, a vacuum breaker and emergency ball valve, a water meter for water-use data, and the ET controller/weather station.

Another property for ET was recruited last week, and this week the push begins to recruit additional research participants. Stay tuned!
