What is the recommended spacing for gate valves in a distribution system?

The recommended spacing for gate valves in a distribution system typically falls within the range of 200 to 2500 feet. This spacing ensures that there are adequate points for isolation and maintenance without putting excessive strain on the system during routine operations and emergencies.

Having gate valves at these intervals allows for effective control of water flow, helps limit the amount of system disruption during repairs or maintenance, and prevents water from being unnecessarily shut off to large areas. This also supports operational efficiency and provides flexibility in system management.

Gate valves are crucial for managing the distribution network, and adequate spacing is important for both operational functionality and safety. It allows for effective isolation of sections of the pipe should a failure occur, enabling maintenance personnel to work on repairs without affecting larger portions of the water system.
