Drip irrigation: Drip irrigation is a great way to address a number of issues related to plant watering techniques, water use reduction programs, and environmental impact. With drip, as opposed to overhead irrigation, it is possible to get the desired moisture placed ideally close to the plant's roots without spraying it all over adjacent plantings, sidewalks and driveways, or your neighbor's car.
In its simplest form, a drip system consists of a source (typically a high-pressure tap after a water meter), a pressure reduction valve to get the supplied line pressure reduced to that suited to the system, a back-flow device to prevent contaminated water from getting into the domestic water supply, a manual valve (or electronic controller and electric valves) to operate the system, main line pipes, lateral, or branch, lines to actually distribute the water, and emitters in, or attached to, the branch lines.
