Purpose of a zone map in irrigation design?

• A. Identify water source quality.
• B. Document zone boundaries, controller assignments, valve locations, and head types for installation and maintenance.
• C. Schedule irrigation times.
• D. Measure soil moisture.

Answer: (B)

A zone map is a documentation tool that records how the irrigation system is laid out and wired. It shows where each zone begins and ends, which valve controls each zone, where those valves and controllers are located, and what head types are installed. This clear layout makes installation and maintenance much easier, because technicians can quickly identify the exact hardware in each zone, understand how it’s wired, and perform repairs or replacements accurately. It also helps with future changes or upgrades by providing a reliable reference that matches the field setup to the design. The other functions aren’t the purpose of a zone map. Water source quality is determined through water testing and analysis, scheduling irrigation times is handled in the controller’s programming, and soil moisture is measured with sensors or probes.
