Access & Inspection Chambers (Adoptable & Non- Adoptable)

Following the publication of Sewers for Adoption 7 (SfA7) outlining revised performance criteria, newly-defined design detailing and installation standards for all adoptable drainage networks including manholes and inspection chambers, Brett Martin have developed a range of Adoptable Inspection and Access Chamber Assemblies in 315mm and 450mm diameters. This ensures our full offering of Inspection and Access Chambers satisfy the requirements set out in Sewers for Adoption 7 (SfA7) and Building Regulations Part H1.
