Terlan

What Terlan does

Terlan S.A. is a Poznań, Poland-headquartered infrastructure construction company founded around 2000, operating as the construction and rehabilitation arm of the Aquanet Capital Group. The firm serves municipal governments, local water utilities (PWIK), and transport authorities as a general contractor (generalny wykonawca) on water and sewage networks, wastewater treatment plants, water treatment stations, roads, bridges, and tramway infrastructure across at least six Polish voivodeships. Its core technical competency is trenchless (no-dig) rehabilitation, offering the full CIPP spectrum (UV-cured fiberglass, hot water-cured felt, steam-cured glass), Coverlan centrifugal polyurea-basalt composite coating, PE and GRP-module relining, static cracking, close-fit technology, spot rehabilitation packers, and HDD directional drilling, alongside CCTV and Smartball network monitoring. Headcount is 51-100 employees and the firm maintains a registered headquarters at ul. Lutycka 95, Poznań.

Terlan generates revenue through three streams: (1) one-time project-based construction contracts awarded via Polish public procurement (PRL tenders, EU co-funded programs such as FEnIKS 2021-2027), evidenced by individual contracts valued at 47-100 million PLN each; (2) recurring network operation and maintenance services under Comprehensive Service Agreements (KUS), including 24/7 monitoring, leak detection, and pipe repairs for utilities such as Aquanet SA; and (3) product revenue from Komcel, an organic soil improver produced at its composting facility from processed sewage sludge. Customer acquisition occurs through direct enterprise field sales into public tenders, reinforced by conference sponsorship (XVII WOD-KAN conference) and integration within the Aquanet Group ecosystem. Distribution is exclusively B2G, with no retail or consumer channels and no publicly disclosed pricing. Notable flagship projects include the Świecie WWTP consortium with Melbud S.A. (~$25M USD), the Miękinia Water Treatment Station, the Kórnik 15.6 km DN500/DN400 main pipeline (2021-2024), the Tramwaj w Ratajczaka project for Poznańskie Inwestycje Miejskie, and DN2500 GRP-module rehabilitation of a major Poznań sanitary collector.
