The purpose of the Grid System is to provide circulating feed from several mains.

Explanation:
The grid system is an interconnected network of water mains designed to allow cross-feeding and circulation between multiple lines. This setup provides redundancy and stable pressure, so water can be drawn from several mains and circulated to balance flow. If one main drops in pressure or is taken offline, others can still supply hydrants and apparatus, reducing the risk of a pressure drop during high demand. This is the specific purpose of the grid system: to provide circulating feed from several mains. The other terms refer to parts or the overall network, not the grid’s cross-fed, circulating function.
