Osma offer a wide range of drainage products, including Osma guttering, drain fittings and rainwater accessories. Their inspection chambers are used to provide access to underground systems for inspection, cleaning, and maintenance. They’re typically installed at key junctions or changes in direction within foul and surface water pipework. Modern Osma systems are designed to be modular and lightweight, with components that meet BS EN 13598 standards. Most installations involve plastic bases, risers, and covers. You’ll often see them used with 110mm or 160mm Osma pipe systems in residential and light commercial projects.
