Utilizero: Helping water utilities in the race towards zero

Welcome to Utilizero, a collaborative partnership between DHI, a leading advisory company specialising in sustainable development of global water resources, and Aarhus Vand, Denmark’s foremost water utility renowned for its innovative approach to tackling water challenges. At Utilizero, we’re dedicated to supporting wastewater utilities worldwide in their journey towards adopting climate-neutral solutions, including automated water treatment  processes. Through advanced process management and operational optimisation, we empower utilities to slash energy consumption by up to 30% while curbing emissions of greenhouse gases and chemicals


Harnessing innovative solutions from Denmark and capitalising on the expertise of prominent Danish water utilities, we demonstrate the transformative potential of heightened automation and digitalisation within the industry, particularly in mitigating its climate impact. Our bespoke services empower global water utilities to realise significant reductions in energy consumption and carbon emissions, achieving reductions of 20-30%, while concurrently adhering to stringent effluent standards and reducing operational expenditures. The adoption of our solutions consistently delivers compelling business propositions, with return on investment (ROI) periods as brief as 6-24 months, offering a compelling alternative to capital-intensive infrastructure investments.
