TThere are many cases in which remote power is needed for irrigation systems. This irrigation might be for agriculture or for domestic purposes (lawns etc.) To demonstrate a “Remote” Irrigation system, a prototype unit was constructed on the grounds of Culligan Water Conditioning and Wilderness Trace Solar on North Stewarts Lane in Danville Kentucky. Even though Electrical Grid power is available onsite, this unit is completely “Off-Grid”

This irrigation system uses rainwater collected from the roofs of both businesses and from a Stormwater Sump located on the property. The rainwater is stored in a 25,000 gallon Rainwater Storage System The Rain Water Collection and Storage System is shown.

Most of the remote power needed is for the Irrigation pump. The pump used for this case is a Grundfos “Gator” 1.5 Horsepower 115V Centrifugal Pump. A small amount of electricity is also needed for the Nine Station Irrigation controller. The process Diagram for this prototype system is given below.
