Source of Water in Lerwick, United Kingdom

Tap water in Lerwick comes primarily from surface water stored in the Loch of Girlsta on mainland Shetland. Scottish Water abstracts this water and sends it to the Lerwick Water Treatment Works.

At the treatment works, the water is filtered and disinfected before entering the public supply network. Scottish Water then distributes it through mains to homes and businesses in Lerwick.

Lerwick Drinking Fountains

Public drinking fountains in Scotland are generally safe to use when they are connected to the mains supply, properly maintained, and marked as suitable for drinking. Water supplied through the public network must meet strict Scottish drinking-water standards.

Do not use a fountain showing an “out of order” or “not drinking water” notice, or one that appears damaged or poorly maintained. Let the water run briefly before drinking, particularly if the fountain has not been used recently.
