Overview
A city project covers storm drains along flooded roads and the pressure in the buried mains beneath them. Crews relied on calls from the public and on patrols after heavy rain. By the time a crew reached the drain, water was already standing and traffic had slowed.
The programme set two goals. First, road ponding had to be reported while it was forming, not afterwards. Second, the pipeline network had to be watched at the same time, so valves could be opened and the water sent to the river before damage spread.
Challenges
Storm water reported by the public
Crews learned about standing water from calls and from patrols after heavy rain, by which time traffic had already slowed.
A drain reached after the fact
By the time a crew arrived at a road drain the water was already standing, and the window to open it early had passed.
Pipeline watched separately
The buried mains and the road drains were read on different records, so a pressure change and a rising level could not be seen as one event.
Solution
Level and pressure readings leave each transmitter over the WES-WIO wireless terminal protocol. The edge gateway collects the wired and wireless nodes and holds the last value if the link drops. One uplink carries the whole site to the WES device management platform.
On the platform, a rising level crossing its threshold sends an alert to the municipal screen and to the duty engineer at once. The same event opens the storm drain relays through the gateway, and pipe pressure is checked against its own band before any valve moves.
