What is a primary reason for maintaining adequate water pressure in a distribution system?

Maintaining adequate water pressure in a distribution system is critical primarily to ensure a sufficient flow rate for consumption. When water pressure in the system is adequate, it allows for an efficient movement of water from the distribution system to consumers' taps and appliances. This is particularly important in meeting the demands for everyday activities such as drinking, cooking, cleaning, and sanitation. If the pressure is too low, it may lead to inadequate service levels, where consumers experience slow flow rates or even interruptions in water supply.

The relationship between pressure and flow is essential; sufficient pressure facilitates the ability to move larger volumes of water quickly. In contrast, low pressure can result in some consumers not receiving water at all, especially those located at higher elevations or farther down the distribution line. Therefore, maintaining appropriate water pressure is fundamental to the overall functionality and reliability of a water distribution system.
