About us

The Tech Company Hias

Our story started with a heavily eutrophicated lake and a governmental funded action plan, «Save the lake Mjøsa» back in the 1970’s. A pillar in the NOK 1,4 billion action plan was the foundation of the utility Hias IKS and the construction of Hias WWTP in 1974. Ever since, Hias IKS has been a frontrunner among Norwegian utilities in adopting and successfully installing state of the art technology. Hias IKS co-developed and installed the first ever Cambi THP in the 1990’s and a CBG upgrade plant in the 2010’s.  When the retrofit with the Hias Process and nutrient recovery is completed in 2021, the Hias WRRF will be among the most cost-efficient, compact, circular and environmentally friendly wastewater treatment plants globally.


Hias is a trueborn child of the utility Hias IKS. Our inheritance is 40+ years of operational experience and a unique ability to develop, adapt and implement technology and concepts.

Our philosphy
