What is an inspection chamber?
An inspection chamber, commonly known as a manhole cover, is an essential part of an underground drainage system. It provides access to drains so they can be cleaned, cleared, and inspected when required. Inspection chambers also play an important safety role by preventing unauthorised access to drainage systems.
How to choose the right one for you?
Choosing the right products for your drainage system is an integral part of planning and design, whether your project is large or small. There are several factors to consider when choosing an inspection chamber, including:
- The size of the pipe
- The type of pipe you have
- Cover level/invert level or depth
- Configuration
It’s important to understand the needs of your project:
- Is your drainage installation adoptable or non-adoptable?
- What is your proposed depth to invert from cover level?
- How many inlets do you need and at which angles?
- What is the diameter of the outlet?
Plastic inspection chambers are now widely used as an alternative to concrete because they offer numerous benefits:
- Safe – lightweight, reducing confined space and machinery risks.
- Versatile – suitable for surface or foul water systems.
- Consistent – factory-produced for high-quality and easy installation.
- Fast – up to 4× quicker to install due to smaller excavation needs.
- Sustainable – recyclable and lowers CO₂ from transport.
- Cost-effective
Benefits of concrete inspection chambers include:
- Economic and versatile
- Reinforced build – durable and reduces site construction costs
- Tongue and groove joint detail for easy placement
- Available in a wide range of sizes suitable for most domestic requirements
