Which spacing pattern provides better coverage and less water waste in sprinkler layouts?

• A. Equilateral triangular spacing
• B. Square layout
• C. Random spacing
• D. Vertical spacing

Answer: (A)

Uniform coverage comes from how the spray zones overlap. Equilateral triangular spacing places sprinklers so their circular coverage areas intersect in a honeycomb pattern, forming a hexagonal grid. This arrangement minimizes the farthest distance any point is from a sprinkler and ensures each point is within reach of multiple heads, giving consistently even water application. The result is fewer dry spots and less overwatering, which means less water waste overall. A square layout tends to leave gaps at the centers of squares and causes uneven overlaps, leading to dry spots or excessive watering in other areas. Random spacing gives unpredictable coverage, and vertical spacing isn’t designed for even distribution. So the triangular pattern provides the best balance of coverage and conservation.
