Aarhus Vand (Denmark), Melbourne Water (Australia), and Severn Trent (UK) form a partnership to advance the future of environmentally friendly wastewater treatment. Partners will collaborate on developing technologies to reduce the carbon footprint of wastewater treatment sites to net-zero, sharing existing expertise, and establishing new international standards for measuring and reporting emissions.

The intention with Aarhus ReWater is to make the world's most resource efficient wastewater treatment plant.

Aarhus Vand have been working strategically to develop energy neutral utilities for decades. It all started with a challenge to save energy and become more efficient, and now, after years of continuous work, we're able to announce, that already now the GHG emissions are 77% lower than in 2008.

Aarhus Vand had planned to increase the capacity of Viby wastewater treatment plant in order to ensure stable and efficient treatment performance.

The architectural firm Henning Larsen has been selected by Aarhus Vand to design Aarhus Rewater, a cutting-edge wastewater treatment plant and urban landmark. Henning Larsen, along with team members Klinges Tegnestue, Topotek 1, and artist Eva Koch, will lead the project.

Our biggest wastewater treatment plant in Marselisborg produced 30 % more electricity than the amount consumed by the plant itself on average between 2015-2019. At the same time the treatment plant produced 75 % more heat than it consumed, resulting in a total net energy production of 150 %.

Climate change involves more precipitation, more heavy rain and more cloudbursts. In Aarhus and all over Denmark, climate change poses quite distinct challenges in areas connected to a public sewer system.
