Vatnsveita

Vatnsveita is Icelandic for waterworks and may refer to a facility or network for treating and supplying potable water in Icelandic municipalities. In Reykjavik, Vatnsveita denotes the central municipal waterworks that supplies drinking water to the city and surrounding areas. The facility encompasses treatment, pumping, storage and distribution infrastructure and operates as a core part of the urban water system. The waterworks collects, treats and distributes water through a network of pipes and reservoirs, with continuous monitoring to ensure water quality and safety.

The development of Reykjavik's water supply occurred alongside the city's growth. Over the 20th century, the Vatnsveita expanded and modernized to increase capacity and reliability, incorporating filtration and disinfection processes and upgrading facilities to meet demand and improve resilience against contamination and drought. The system is operated by Reykjavik's municipal utilities and is coordinated with regional water sources and infrastructure.

Today, Vatnsveita remains a key component of Reykjavik's infrastructure, providing treated water to residents and institutions. Ongoing maintenance and occasional upgrades address aging equipment, capacity needs, and water quality standards, underpinning public health and daily life in the capital. The term itself can also be used to refer to waterworks facilities in other Icelandic towns and villages.
