- Thessaloniki Water Supply & Sewerage Co S.A. (EYAPS.AT) operates as the primary provider of water supply, sewerage collection, and wastewater treatment services in the greater Thessaloniki metropolitan area of Greece. The company manages the full water cycle, including raw water intake from reservoirs and aquifers; production and distribution of potable water through an extensive network of pipelines, pumping stations, and reservoirs; collection of sewage via sewer systems; and advanced treatment at wastewater facilities to meet environmental standards before discharge or reuse. It offers additional services such as water quality monitoring, leak detection and repair, customer metering and billing, and environmental compliance consulting for industrial clients.
EYAPS serves residential, commercial, industrial, and municipal customers across Central Macedonia, with primary operations focused on Thessaloniki and surrounding municipalities, supported by a headquarters in Thessaloniki and regional facilities. Founded in 1987 as a publicly listed société anonyme on the Athens Stock Exchange, the company maintains strategic partnerships with local authorities and has pursued sustainability initiatives, including recent upgrades to its wastewater treatment plants for enhanced biogas production and energy self-sufficiency. In the last two years, EYAPS announced a major expansion project in 2024 involving a €50 million investment in smart water metering technology and digital infrastructure to reduce non-revenue water losses by 20%; formed a strategic alliance with European Union-funded programs for climate-resilient infrastructure; and completed the acquisition of complementary assets from smaller regional providers to consolidate market share in northern Greece, reflecting a shift toward integrated digital water management solutions.
