Inntaket

Inntaket is a Norwegian term that refers to the intake, the point at which water or other fluids are drawn into a system. The term is primarily used in engineering and management of water resources, including hydropower, municipal water supply, and industrial process water. It describes the facility or location where a source such as a river, lake, or reservoir is connected to a conduit, treatment plant, or power system.

In hydropower and large-scale water projects, the intake is designed to withdraw water from the source while controlling debris and protecting aquatic life. Typical features include screens or grates to prevent large objects and, in some cases, fish protection measures, as well as gates or valves to regulate flow. The placement of the intake affects head, efficiency, and sediment management. Environmental and engineering considerations often require assessments of sediment transport, water quality, temperature, and ecological impact.

In municipal water systems, the intake provides raw water for treatment and distribution. It is chosen to balance water quality, reliability, and protection from contamination, and is usually equipped with monitoring equipment, screens, and other protective measures.

Regulation and planning for intakes involve water resource authorities, environmental agencies, and often public consultation. Proper design, operation, and maintenance are essential to ensure a reliable water supply, minimize ecological disruption, and safeguard downstream users.
