Grand Rapids, MI is the larger of the two, with 333,997 more residents than Allendale. Grand Rapids is served by 4 public water systems, compared with 1 in Allendale — a difference of 3 systems. A larger number of systems often reflects a more fragmented distribution network spanning multiple utilities, suburbs, or rural service areas, while a single large utility serving a big population can benefit from economies of scale in treatment and monitoring, but may also face more complex, aging infrastructure to maintain.
