HERA has acquired Sostelia - Water Tech Group for $138.0 million, marking a significant expansion in the water treatment sector. This corporate acquisition sees HERA taking full ownership of Sostelia, a move designed to strengthen its capabilities in sustainable water management and circular economy initiatives.

Sostelia is recognized as the leading Italian player in civil and industrial water treatment. Comprising eight specialized companies-STA, Simpec, NTW, CID, Smart Sea, NPC, Coms, and Trentino Acque-the group offers a comprehensive suite of services across the entire water cycle. These include the design and construction of treatment plants, ongoing management and maintenance, waste treatment solutions, and expert environmental consulting. Sostelia's core mission centers on preserving water as an indispensable resource through advanced systems for its recovery and reuse, thereby actively contributing to a circular economy model.

The acquisition is strategically important for HERA, enhancing its footprint and expertise in critical environmental services. By integrating Sostelia's technological leadership and extensive service portfolio, HERA aims to bolster its offerings in advanced water treatment and resource optimization. This synergy is expected to create a more robust platform for delivering integrated solutions that address the increasing demand for sustainable water practices and contribute to broader environmental goals. The combination will leverage Sostelia's specialized know-how with HERA's operational scale.

Looking ahead, the combined entity is positioned to become a more formidable force in the Italian water technology and environmental services market. This integration is anticipated to drive innovation in water recovery and reuse, supporting the transition towards a more resource-efficient and circular economy across both civil and industrial applications.
