What minimum depth in mm should drainage pipe be buried?

  1. 200mm

  2. 300mm

  3. 400mm

  4. 500mm

The correct answer is: 300mm

The minimum depth for burying a drainage pipe is dependent on a variety of factors, including the type of soil, climate conditions, and location of utilities. While options A, C, and D may seem like viable choices, option B is the most suitable as it allows for proper water flow and reduces the risk of damage from freezing temperatures. A depth of 300mm provides enough coverage to protect the pipe but also allows for easy access if any maintenance or repairs are needed.
