Keyline design is a system of principles and techniques of developing rural and urban landscapes to optimize use of their water resources. Australian farmer and engineer P. A. Yeomans invented and developed Keyline design in his books The Keyline Plan , The Challenge of Landscape , Water For Every Farm , and The City Forest .
An irrigation line with water timer A water timer is an electromechanical device that, when placed on a water line, increases or decreases the water flow through the use of an electro-mechanically actuated ball valve or embedded (solenoid) valve .
Irrigation water has a price by which the management costs must be covered. ... of the irrigation system (i.e. near the system's take-off point) often have preference ...
Jun. 14—The Talent Irrigation District will shut down its entire irrigation system for at least two weeks in a bid to save scarce water during the ongoing drought. "We're going to do our best.
A sprinkler system timer is an electrical device that is used to set an irrigation sprinkler system to come on automatically at a certain time. Irrigation timers first appeared in the early 1960s to control large-radius lawn sprinklers, which at the time usually contained their own electrically operated valve (most golf-course sprinklers still use this type of actuation).
This type of system is known to most people as a "waterreel" traveling irrigation sprinkler and they are used extensively for dust suppression, irrigation, and land application of waste water. Other travelers use a flat rubber hose that is dragged along behind while the sprinkler platform is pulled by a cable.
Most automatic irrigation valves are diaphragm valves in which the water above the diaphragm must be discharged for the valve to open. In a hydraulic system, the controller and valves are connected via small plastic tubes approximately 4 mm (¼ in) in diameter. The controller opens the tube connected to the valve, allowing that valve to open.
The disadvantages of drip irrigation are: Initial cost can be more than overhead systems. Ongoing capital costs related to replacing and maintaining the tubes can exceed water savings if the system improperly designed and set up. Drip irrigation may also be more labor intensive, especially if there is extensive crop rotation necessitating ...
