What population range does the Distribution System Medium (DSM) serve?

The Distribution System Medium (DSM) refers to systems that serve a specific range of populations, which is crucial for determining operational requirements, safety standards, and regulatory compliance. The correct population range for DSM is greater than 3,001 but less than 10,001. This classification helps in establishing guidelines for water quality monitoring, treatment processes, and distribution system management specifically tailored for communities within this population range.

Understanding the operational needs and regulatory frameworks that pertain to this population size is essential for water operators, as it affects the infrastructure design, maintenance schedules, and staffing levels required to ensure safe and reliable water supply. This range is significant because it distinguishes medium-sized systems from larger systems that may have different regulatory requirements and operational complexities.
