Lovö vattenverk, Municipal waterworks in Ekerö, Sweden

Lovö waterworks stands by Mörbyfjärden on the northwestern side of Lovön in Ekerö. Built 1929–1933 to Paul Hedqvist's functionalist designs, its main building has a semicircular tower on the west facade topped by an observation platform with a light steel railing. Raw water is drawn from Lake Mälaren at depths of 5, 10 and 23 metres.

The facility was opened in 1933 by King Gustav V and represented a shift toward automated water processing in the Stockholm area. This development allowed for more reliable and expanded water supply to serve the growing population.

The plant's name comes from Lovön island, where it stands by Mörbyfjärden. Architect Paul Hedqvist gave the main building a semicircular tower on its west facade, topped by an observation platform with a light steel railing that recalls a ship's command bridge. Inside, functionalist details remain visible.

The facility operates with advanced monitoring systems to ensure consistent water quality throughout the region. It functions as an active industrial plant with restricted access, so visitors should not expect public tours or casual visits.

The semicircular tower on the west facade ends in an observation platform ringed by a light steel railing, a detail often compared to a ship's command bridge. Inside, functionalist fittings from the 1933, 1939 and 1960 phases remain, with control equipment supplied by Siemens & Halske AG.
