The Stormwater Information System distributes storm pump operating conditions, etc. to residents in real time via the Internet utilizing a private network that employs optical fibers installed in sewer pipes. Information to be distributed includes advisory and warning information relating to weather data, weather radar information, river information, emergency disaster information, refuge maps, etc. in addition to storm pump operating status information (for example, running, stopped, or failed). Residents can utilize these pieces of distributed information for their use in providing self-help and mutual help for evacuation, protection from floods, and more.
