What ara region bern ag does

ara region bern ag is a Swiss municipal wastewater treatment utility headquartered in Herrenschwanden, Bern, that provides essential public sanitation services to 12 shareholder-municipalities in the Bern region. The company is structured as an Aktiengesellschaft (AG) with CHF 60 million in share capital, 100% owned by the municipalities it serves, with Bern holding 76.58%, Köniz 12.30%, and Muri b. Bern 7.01% of shares. The facility processes approximately 90 million liters of wastewater daily through 16 documented treatment stages combining mechanical, biological, and chemical processes, with a biological stage using 16 cells containing 420 m³ of styropor ball carriers (100 billion 4mm biofilm balls) and three anaerobic digestion towers of 6,000 m³ capacity each.

The company's technology stack integrates wastewater treatment with renewable energy production. Biogas from anaerobic digestion is upgraded to biomethane meeting natural gas quality standards (≥96% methane), and a 5 km saturated steam pipeline (Querverbund) operating at 240°C and 40 bar distributes industrial heat to neighboring facilities. Heat recovery systems save 600,000 liters of heating oil annually and reduce CO2 emissions by 1,315 tonnes per year. The facility also operates a photovoltaic solar system commissioned in 2021 and is currently ramping up a fourth treatment stage with 20 activated carbon reactors for micropollutant removal, with first water introduced in July 2026.

Revenue is generated through regulated municipal service fees and tariffs set by cantonal authorities, with ancillary income from biogas/biomethane sales, industrial heat supply, and acceptance of external biogenic waste for codigestion. The company does not engage in commercial marketing or customer acquisition; its 12 municipal shareholders are simultaneously its customers and owners. As a public utility, ara region bern ag also provides facility tours and educational programs for schools, visitors, and international delegations as a community engagement function.
