Water plant in Gothenburg (Sweden) implements Xylem UV solution in complex space and reduces energy use by 20%, and environmental footprint by 500kg of CO2-equivalent over each UV lamp lifetime

Gothenburg, Sweden


Challenge: The city of Gothenburg, Sweden’s second largest city, supplies water from two drinking water plants to the city’s 500,000 inhabitants. Xylem was tasked with providing a validated ultraviolet (UV) solution that would fit and operate in the 62 year old plant which had not been originally built to facilitate such technology.

Solution: A CFD model of the Spektron UV reactor and final piping arrangement for the Gothenburg WTP was developed to predict flow fields and hydraulic behavior within the piping and reactor at the given design parameters. The Spektron UV systems also offered the lowest lifecycle costs.

Benefit: Thanks to Xylem’s inventive solution, the drinking water produced at the plant now benefits from an additional stage of UV protection against microorganisms – a sustainable, chemical-free solution.
