New climate-friendly waterworks will secure Frederiksberg's future drinking water supply


A new waterworks with a softener plant will supply the city of Frederiksberg with drinking water with an environmentally and economically sustainable method and will secure the city’s future water supply. Gottlieb Paludan Architects provides architectural expertise on the project.

The waterworks will treat water from Frederiksberg Forsyning’s own drills as well as purchased water from HOFOR, in order to ensure a sufficient volume of water up to 785,000 liters per hour. The water is purified, filtered and softened separately before it is mixed in the waterworks' distribution reservoirs and disinfected before it is distributed to consumers.

With the softener plant, the new waterworks will lower the water’s hardness from 22-30 dh to approx. 10 dh which will reduce limescale in water pipes and installations throughout the city. This will, in turn, lead to reduced energy consumption and thus a lower CO2 footprint. The waterworks thus make a positive contribution to four of the UN's 17 Sustainable Development Goals; "Clean Water and Sanitation", "Affordable and Clean Energy", "Sustainable Cities and Communities" and "Climate Action".

The waterworks will be based on modern, high-quality technical solutions and will provide Frederiksberg with homogeneous, soft water from 2022. The new waterworks will be built on Frederiksberg Forsyning’s site at Stæhr Johansens Vej 38 and the project will commence in the spring of 2020.

The winning team consists of the environmental company Krüger and the contractor group Arkil with NIRAS and Gottlieb Paludan Architects as sub-consultants.

The original  heating system was also designed by Gottlieb Paludan Architects in the 1970s and we have been responsible for all extensions and reconstructions since then.
