The Office for Water and Waste of the Canton of Berne obliges the operators of wastewater treatment plants (WWTP) to comply with the discharge conditions for treated wastewater into water bodies even in the event of a power failure. Therefore, the operators of the WWTP must install an emergency power supply that can guarantee the operation of the essential plant components. WWTP Villeret, which treats the wastewater of around 12,000 population equivalents in the municipalities of Renan, Sonvilier, Saint-Imier and Villeret, had to rebuild its electrical systems so that it could disconnect its combined heat and power plant, which runs on sewage and biogas, from the public grid and start it on battery power in emergency operation. Emergency load operation is controlled via the process control system.
