What is the definition of a water control? A water control is a device or system designed to manage, measure, or regulate the flow of water. It is used to maintain a desired level in tanks, canals, reservoirs, and other bodies of water, as well as to regulate the pressure or flow of water in systems like fire sprinklers, plumbing, and irrigation systems. Water controls can be manual or automated, and they can be either operated actively or passively. Manual water controls are operated by manually adjusting a valve or pipe to adjust the flow of water, while automated water controls are adjusted with a remote control or programmed settings. Passive water controls involve the use of natural elements such as gravity or the movement of tides to move water through the system. Water controls are used to ensure that water is flowing at the correct rate for the intended purpose, and to protect against floods or drought. They are also used to conserve water by limiting the amount of water that is used. Water controls can
