Head works refers to a complex system of structures and machinery that are designed to control and manage the flow of water in various industrial, agricultural, and municipal applications. Primarily used in the context of managing rivers, canals, or water supply systems, head works play a crucial role in ensuring efficient water distribution and control.
In a river or canal, head works typically consist of a dam, spillway, and various gates or valves that regulate the flow of water. The dam creates an artificial reservoir, which can be used for storing water during periods of high flow or releasing water during periods of low flow. The spillway allows excess water to be safely released from the reservoir, preventing flooding or overloading the system. Gates or valves are used to divert water into different channels or pipes, routing it towards the desired destinations.
In a water supply system, head works may include intake structures, such as weirs or screens, which help filter out debris or sediment from the incoming water. Pumping stations and treatment facilities are also considered part of the head works infrastructure, as they are responsible for extracting, purifying, and distributing water to consumers.
Overall, head works serve as the critical starting point for water management systems, providing the necessary infrastructure for controlling, storing, and distributing water resources efficiently and sustainably.
