In Indian architecture, the Indian Water Closet (WC) with a P-trap is a common sanitary fixture designed to ensure hygiene and efficient waste management. The P-trap is a U-shaped pipe located below the toilet that holds a small amount of water, creating a seal to prevent foul gases from the sewage system from entering the building.
This type of trap is particularly effective in maintaining hygiene and odor control, making it a popular choice for Indian-style squat toilets and modern water closets alike. The P-trap is typically used when the drainage outlet is horizontal or located in the wall, ensuring smooth wastewater flow while minimizing blockages.
Its simple yet effective design aligns well with both traditional Indian construction practices and contemporary architectural standards, balancing functionality, sanitation, and ease of maintenance.

An Indian WC with a P-trap in construction involves several key components that need to be precisely arranged to ensure proper functionality, hygiene, and ease of maintenance. Here’s a detailed description:
Toilet Pan:
- The Indian-style squatting pan is installed at floor level, with its slope directed toward the P-trap for efficient waste flow.
- The pan is securely fixed into the flooring, ensuring stability and proper alignment with the trap.
P-Trap Placement:
- Positioned directly below the pan, the P-trap is a U-shaped pipe designed to retain water, creating a barrier against sewer gases.
- The inlet of the P-trap connects to the toilet pan outlet, ensuring a seamless flow of waste into the drainage system.
Outlet Connection:
- The P-trap’s outlet is aligned horizontally to connect to the drainage pipe, usually embedded into the floor or wall.
- The diameter of the outlet pipe is typically 100 mm, matching standard plumbing practices for efficient waste removal.
Floor Slope:
- The surrounding floor is sloped gently toward the pan to prevent water stagnation and ensure effective drainage.
Ventilation Pipe:
- A vent pipe is connected to the drainage system to release sewer gases, preventing pressure buildup and maintaining a smooth flow.
Water Supply and Flushing System:
- A tap or flush valve is installed nearby to facilitate manual or automatic flushing.
- In some installations, a cistern with a flush pipe directs water into the pan for thorough cleaning.
Finishing and Sealing:
- The floor around the pan is sealed with waterproofing material to prevent leaks.
- Tiles or other non-slip surfaces are applied for safety and ease of cleaning.
