A system for remotely managing a network of waste containers (12), each of which is associated with a monitoring unit (38), utilizes a central computer (50) having a communication link to each monitoring unit (38). The central computer (50) provides a dynamically updated display, via a display module (60) having a full container window (or zone) which shows full containers (12), an alarm window (or zone) which shows non-full containers (12) having an alarm condition, and a container status window (or zone) which shows non-full containers not having an alarm condition. The system additionally includes one or more remote monitors (404) capable of providing user access to the container status information maintained by the central computer (50, 402).
