What is AWWA's recommended maximum distance between valves in a residential area?

The American Water Works Association (AWWA) recommends a maximum distance of 800 feet between valves in residential areas to ensure effective operation and maintenance of the water distribution system. This guideline is based on the need for accessible shut-off points for repairs, maintenance, or emergency situations that may arise within the distribution network. Spacing valves at this distance allows for a more manageable section of the pipeline to be isolated if necessary, minimizing the impact on the surrounding residents and ensuring a prompt response to any issues.

In residential areas where water service interruption can significantly affect daily living, having valves no more than 800 feet apart is a practical measure to maintain service continuity and improve operational efficiency. Additionally, this spacing assists in minimizing the risk of flooding and water damage during repairs, as it allows for quick isolation of smaller sections of the system while reducing the number of customers affected.
