helps water utilities in the race towards zero


Utilizero’s purpose is to contribute to a climate-positive global wastewater sector through digitalisation and skills enhancement.

Solutions developed in Denmark and experiences from Danish wastewater utilities prove that increased automation and digitalisation can make a critical difference to the global wastewater sector’s climate footprint. International water utilities can reduce current and future energy usage and carbon footprint by 20-30% while meeting effluent requirements and reduce operational costs.


Utilizero has been established by DHI, the internationally renowned advisory company specialised in sustainable development of global water resources, and by Aarhus Vand, one of Denmark’s largest water utilities and an international frontrunner in developing sustainable solutions for the water challenges of the future. Together, the two companies will support global wastewater utilities in the transition into more climate-neutral solutions such as automated cleansing processes. With process management and operational optimisation, wastewater utilities will be able to reduce energy consumption with up to 30 % and reduce the emission of greenhouse gasses and chemicals.

Lars Schrøder, CEO Aarhus Vand A/S, and Mette Vestergaard, CEO DHI A/S, sign the agreement on Utilizero on 1 February 2023


The solutions offered by Utilizero are based on DHI’s unique software technologies and Aarhus Vand’s years of experience from their own digital transformation within e.g. cleansing processes and process optimisation. Utilizero is a natural continuation of DHI’s and Aarhus Vand’s joint objective of accelerating the green transformation in the global wastewater industry.
