What are distribution loops in a water system?

Distribution loops in a water system are designed specifically to enhance water quality by promoting circulation throughout the network. This circulation prevents stagnation, which can lead to water quality issues such as the growth of bacteria and the accumulation of sediments. By ensuring that water continually flows through different parts of the system, loops help maintain optimal conditions and ensure that the water delivered to consumers is fresh and safe for use. This is particularly important in managing temperature and chemical stability of the water, thus reinforcing the overall health of the distribution system. Other features, while important for various aspects of water distribution, do not directly address the primary purpose of maintaining water quality through circulation.
