Most subdivision these days are built with irrigation piped to the lots. Connected to that line is a saddle and curb stop valve that supplies water to the individual lot owner. Each subdivision is different when it comes to ownership and deliver of water. Some communities own the mainline and pump and become the irrigation provider. In other subdivision they are owned and maintained by an irrigation district. Please make sure you are aware of how this is setup in your specific community. Where we live in Idaho Irrigation begins normally around April 15thof each year and runs to October 15th, give or take a day or so.
