What is the recommended distance for placing valves in water mains?

The recommended distance for placing valves in water mains is 1,000 feet apart. This standard is in place to ensure that valves, which control the flow of water and facilitate maintenance operations, are adequately separated to minimize the impact of any single valve failure on the system. By aligning with this distance, utility workers can more effectively isolate sections of the water main for repairs or maintenance without disrupting service to larger areas. A greater distance allows for proper water flow management and aids in quicker response times during emergencies.

Although other distances might be proposed in different contexts or systems, the 1,000-foot spacing strikes a balance between operational efficiency and maintenance practicality in most water distribution systems.
