What is the name of a map that provides detailed drawings of the distribution system's zones?

• A. Sectional Maps
• B. System Overview Map
• C. Zoning Map
• D. Atlas Map

Answer: (A)

Sectional maps provide the distribution system drawn in detailed sections or zones, showing what belongs to each area and the features inside it—pipes, valves, hydrants, storage, and other equipment. This level of detail is essential for operations because it lets you isolate a problem to a specific zone, plan maintenance without disrupting the entire system, and manage pressure and flow within that zone. It also makes it easier to locate valves or hydrants and coordinate work across different parts of the network. In contrast, a System Overview Map tends to show the whole system at a broader level, a Zoning Map focuses on land-use boundaries rather than water distribution, and an Atlas Map is a general collection of maps not specialized to the distribution network’s zone-by-zone drawings.
