Halomi Street Sewer Rehabilitation
Project Scope
184 m DN1200
Application
SPR TM RO
Rehabilitation Process
The Rota-LOC technology met all project-specific requirements and technical specifications, fully complying with the structural, operational, and environmental criteria established for the rehabilitation works. Owing to its proven reliability, compatibility with the site conditions, and its ability to ensure rapid, trenchless execution without compromising pipeline integrity or traffic flow, this method was ultimately selected as the most suitable
solution for the project. The rehabilitation carried out using the Rotaloc technology delivered fully satisfactory results. The installation was executed in complete accordance with the relevant technical specifications and regulatory requirements, and the implementation process was completed within a notably short timeframe. The method ensured a high-quality outcome while minimizing disruption, thereby fully meeting the expectations set for the project
Halomi Street Sewer Rehabilitation Project Overview
The Halomi Street Sewer Rehabilitation project in Budapest (Client: Fővárosi Csatornázási Művek Zrt.; Distributor: Sekisui Chemical GMBH; Partner: Agriapipe Kft.) required a fast, trenchless solution due to severe internal corrosion caused by hydrogen-sulfide exposure and the pipe’s location beneath a heavily trafficked roadway. The RIB Loc / Rota-LOC trenchless technology was selected for its proven structural reliability, compatibility with site conditions, and ability to minimize surface disruption. Installed between November 3–18, 2025, the method fully met all technical, structural, and environmental requirements. The rehabilitation was completed quickly, without traffic impact, and delivered a high-quality, fully compliant restoration of the pipeline. Aggressive wastewater from the upstream regional sewer network had caused significant biochemical and chemical corrosion along the interior surface of the pipeline. Prolonged exposure to hydrogen-sulfide–induced acidification and anaerobic by-products led to visible deterioration of the pipe wall, confirming the need for comprehensive rehabilitation
