What is the primary purpose of a grid system in water distribution?

The primary purpose of a grid system in water distribution is to ensure redundancy. This design allows for multiple pathways for water to travel through the distribution system. In the event of a break, shut-off, or maintenance work on a primary line, water can still be routed to consumers through alternative paths. This redundancy not only aids in maintaining a continuous water supply but also contributes to the reliability of the water distribution system, ensuring that consumers have access to water even when parts of the system are compromised.

In contrast, while a grid system can potentially improve flow rates and enhance water pressure by creating more branch pathways, these are secondary benefits rather than the primary objective. Similarly, a grid system does not specifically focus on collecting surface runoff as this is a separate function typically associated with drainage systems rather than water distribution networks.
