Enersense wins contract for maintenance of new wastewater treatment plant in Tampere Enersense International Plc | Investor News | May 13, 2025 at 16:02:00 EEST Enersense, an enabler of the green energy transition, and Tampere Region Central Wastewater Treatment Plant Ltd have signed a contract for the maintenance of a new wastewater treatment plant being built in Tampere. An efficient wastewater treatment process helps keep the region’s waterways clean. The project is a major undertaking for Tampere and the surrounding municipalities. A new wastewater treatment plant is being built in Sulkavuori, Tampere. Even though the population in the Tampere region is growing – along with the volume of wastewater – the load on Lake Pyhäjärvi and the downstream water bodies will decrease, improving their recreational value. Biogas will be produced from the wastewater sludge, providing electricity and heat for the plant’s own use. The Sulkavuori underground treatment plant will replace two aging wastewater treatment plants in Tampere as well as the Lempäälä wastewater treatment plant. The wastewater treatment plant is located underground. The rock excavated to make way for the new facility was used to form Näsinsaari, an artificial island that is now part of the Tampere tram route. Enersense invests in preventive maintenance Enersense is responsible for the maintenance and availability of the plant and two wastewater pumping stations. The contract also covers maintenance tasks related to the underground rock caverns and the facility buildings. In practice, the equipment includes pumps, conveyors, tanks, pipelines, and filters—all requiring strong process expertise. “The plant is innovative and highly automated. A facility like this cannot afford to stop, so everything must operate around the clock. We focus on preventive maintenance to ensure that the equipment runs smoothly at all times,” says Mikko Luoma, responsible for services in the Industry business. “It’s great to start the collaboration at the Tampere central wastewater treatment plant. Our goal is to be a reliable and efficient lifecycle partner that continuously develops operations,” says Luoma. The Tampere wastewater treatment plant is a new project for Enersense. The company has previous experience in wastewater treatment processes, such as in the forest industry and at Helen’s thermal plants in Helsinki. The first wastewater will be treated at the plant in the fall of 2025, and the facility will be fully operational by the end of the year.
