Inspection chambers 🕳️
Also known as manholes, are an important part of any drainage system. These access points allow drainage professionals 👷🏻♂️to inspect and survey drainage infrastructure and perform essential repairs and cleaning work 🧹
The installation and maintenance of inspection chambers are crucial to keeping domestic and commercial drains in perfect working order, which is why property owners and residents need to understand how they work and what is required to keep them well maintained 👨🔧
What is an Inspection Chamber/Manhole❓
An inspection chamber is a sectional entry point that typically consists of a base, sealed sectional risers and a manhole cover made of steel, brick 🧱 , concrete or plastic.
They are situated along the length of the drainage system and are most typically found at key intersections, such as where:
💧 A branch drain joins the system’s main drainage pipe
💧 There is a straight run of piping extending more than 22 metres
💧 A drain or sewer pipe changes direction horizontally by more than 30 degrees
💧 There is a change in pipe size
Inspection chambers are usually designed to be large enough to allow a person to climb inside to perform an inspection or repair of the piping system, although this is not always the case. CCTV drain surveys and water jetting can be carried out via manhole chambers in order to remove blockages 🪠
