Inspection Chambers

Our comprehensive range of inspection chambers gives you options for every non-adoptable and adoptable application. In some cases, one project may use a mixture of both solutions. To get things right from the start, our specialist consultants are happy to help you plan and deploy a solution that’s effective, cost-effective and compliant.

Adoptable Applications
According to the new Sewers for Adoption 7th Edition guidelines, lateral drains and sewers that serve two or more properties and connect to the UK public sewerage network are now the responsibility of the relevant water and sewerage company. Our new range of inspection chambers to BS EN 13598 can be used in these scenarios.


Non-Adoptable Applications
Drains that only serve individual properties remain the responsibility of each householder. Polypipe inspection chambers to BBA approvals or BS 7158 in 320mm and 460mm diameters can continue to be used in these applications, for both shallow access and non-man entry installations.
