What is the minimum depth cover requirement for pipe installations in non-freezing locations to prevent mechanical damage?

• A. 24 inches
• B. 30 inches
• C. 36 inches
• D. 42 inches

Answer: (B)

The minimum depth cover requirement for pipe installations in non-freezing locations is indeed 30 inches. This requirement is set to ensure that the pipes are adequately protected from potential mechanical damage, which can occur due to surface activities such as vehicular traffic or construction work. Covering the pipes to this depth provides a sufficient buffer against these risks. The standard recognizes that while frost protection is a concern in freezing locations, in non-freezing areas, the main purpose of this depth is safeguarding the integrity of the pipes against external forces. Therefore, installing the pipes at a depth of 30 inches helps to strike a balance between providing sufficient protection and allowing for practical installation practices.
