In plumbing and architecture, IC Detail refers to the Inspection Chamber Detail. An Inspection Chamber (IC) is a crucial access point in the underground drainage system, allowing for inspection, cleaning, and maintenance of pipelines.
It typically consists of a concrete or plastic chamber with a removable cover, strategically placed at points where pipes join, change direction, or slope.
The IC detail in architectural and plumbing drawings includes the chamber’s dimensions, depth, materials, pipe connections, invert levels (the lowest point inside the pipe), and cover specifications.
Proper detailing ensures easy access for maintenance, prevents blockages, and promotes efficient drainage flow, making it a key element in a well-designed plumbing system.

An IC (Inspection Chamber) Detail in construction is typically described through key elements and specifications. Here’s a written description of a standard IC detail:
Chamber Structure:
- Shape: Usually square or circular.
- Material: Commonly constructed with brick masonry, precast concrete rings, or PVC.
- Internal Dimensions: Typically around 450 mm x 450 mm or 600 mm x 600 mm for residential systems, but larger for commercial or industrial use.
- Depth: Varies depending on the system but often ranges from 600 mm to 1500 mm.
Base (Invert Level):
- Material: Concrete base with a thickness of around 100 mm to 150 mm.
- Channel: A pre-formed channel or benched base directs the flow of wastewater.
- Slope: Side benching sloped at about 1:12 for easy flow and to prevent debris accumulation.
Pipe Connections:
- Inlet and outlet pipes are positioned at appropriate levels, ensuring a smooth flow of wastewater.
- Pipe diameters typically range from 100 mm to 150 mm for residential use and larger for commercial applications.
- Joints are sealed to prevent leakage.
Cover and Frame:
- A removable cover made of cast iron, ductile iron, or reinforced concrete.
- The frame is securely embedded into the top of the chamber.
- Covers are graded based on load-bearing capacity (e.g., light-duty for pedestrian areas and heavy-duty for vehicular zones).
Ventilation (Optional):
- Some ICs incorporate ventilation pipes to prevent gas buildup.
Positioning:
- Installed at critical points such as pipe junctions, changes in direction or gradient, and every 30 to 40 meters in straight pipeline runs.
