SOA Category OG6
Working on aqueducts, pipelines, gas networks, irrigation systems, and sewer networks with SOA qualification
The OG6 category of the SOA certification system covers network-based infrastructures for water and energy distribution: aqueducts, gas pipelines, oil pipelines, irrigation systems, and sewer networks. It is one of the strategic general categories, as it ensures the distribution of essential resources such as water and gas, as well as the collection and treatment of wastewater. OG6 includes aqueduct systems with pumping stations and reservoirs, water-distribution networks, sewer and drainage systems, and gas and oil pipelines for energy transport.
Fields of application: water networks, sewers, irrigation system and energy pipelines
OG6 applies to a wide range of infrastructure works linked to the transport of water, gas, and other fluids. Key sectors include:
- Potable-water aqueducts and distribution networks: construction of conduits for water supply and distribution, including reservoirs, pumping stations, valves, and remote-monitoring systems.
- Sewer networks and drainage systems: installation of wastewater and stormwater collectors, separate or combined sewer systems, lifting stations, and microtunnels leading to treatment plants.
- Agricultural irrigation systems: construction or modernization of irrigation networks and canal systems with pumping and filtration components to optimize water use.
- Gas pipelines and distribution networks: installation and maintenance of regional pipelines and urban gas networks, with valves, cathodic protection systems, and safety devices.
- Oil pipelines and liquid‑fluid conduits: construction of pipelines for petroleum or chemical products, including pumping stations and leak‑detection systems.
Categories that integrate with OG6
- OS1 – Earthworks: OG6 projects always include trenching and excavation. While OG6 firms may perform these works directly, complex or large‑scale excavations (unstable soils, deep trenches) may require OS1 or specialized subcontractors.
- OG3 – Roadworks and reinstatements: when pipelines run beneath roads or urban areas, OG3 is required for road reinstatement, paving, and signage.
- OS22 – Water‑treatment and purification plants: OG6 covers the network, while OS22 covers the treatment plants. In complex projects, OG6 installs the pipelines and OS22 handles tanks, equipment, and treatment processes.
- OS35 – No‑dig technologies: OG6 and OS35 often work together in projects that require trenchless methods such as horizontal drilling, relining, or pipe jacking, especially to avoid surface excavation.
- Accessory categories: OS21 (special foundations), OG1 (technical buildings), OG8 (hydraulic canalization or river defenses), and OS30/OG11 (technological plants).
FAQ
SOA Category OG6
OG6 represents the backbone of Italy’s water‑energy infrastructure: aqueducts, sewers, gas pipelines, and oil pipelines that ensure water supply, energy distribution, and environmental safety. Investing in OG6 means contributing to the modernization of national networks, reducing waste, and strengthening the resilience of essential public services.
For companies, obtaining OG6 certification is a decisive competitive advantage: it enables access to major public and private tenders, strengthening credibility and positioning in the network‑infrastructure market.
