1. Shallow Manholes (Inspection Chambers)

- Features: Smaller size, lighter lids, and sometimes a flat or sloped top.

- Depth: 3 to 6 feet (approx. 0.9 to 2 meters).
- Purpose: Most common type for routine access to sewer, drainage, or utility lines in residential and commercial areas.
- Features: Made from precast concrete rings with a conical top, they offer standard access and often include built-in steps or ladders.
3. Deep Manholes (Deep Utility Access)
- Depth: Greater than 6 feet (over 2 meters).
- Purpose: Used where utility lines run at significant depths, providing full access for maintenance crews.
- Features: Heavier covers, built-in ladders or rungs for descent, and robust construction to handle greater depths and traffic.
