In irrigation design, why is it essential to locate utilities before trenching?

• A. To avoid damaging lines and ensure safe installation
• B. To simplify permit applications
• C. To fix soil fertility near utilities
• D. To determine sprinkler head color

Answer: (A)

Locating utilities before trenching is about preventing harm and ensuring a safe, reliable installation. Digging without knowing where underground lines run can accidentally cut water mains, gas pipes, electrical cables, or communication lines. Hitting any of these can cause dangerous leaks, fires or explosions, electrical shocks, service outages, and costly delays or repairs. By having utility marks, you can plan a trench route that avoids these hazards, choose appropriate digging methods, and coordinate with utility owners if a line must be crossed. This safety-focused step protects people, property, and the irrigation system itself. The other options don’t address the real risk or safety implications of digging near underground utilities.
