There are five different possible symbols on the map and each one is described below.
Unmonitored: The small light grey dots are outfalls to the lakes/rivers that can be a source of sewage overflow to the environment, but are locations that do not yet have the capability of displaying real-time information. Utilities Kingston has been monitoring, to some extent, many locations over the preceding years and we have taken efforts to ensure we have the capability of displaying data for the locations that have overflowed once, on average, every year or more, between 2010 to 2016. These unmonitored locations will be brought online when facility upgrades permit them to be added.
Monitored, but out-of-service: These are black circles on the map. These are locations that have real-time monitoring, but are temporarily out-of-service. They may be out of service for one reason or another, including establishing a new location, general maintenance, testing, calibration or replacement of equipment.
Monitored: No Overflow: These are green circles on the map. These are locations that have real-time monitoring and have not registered an overflow event within the last 48 hours. In other words, there is no overflow at that location nor has a recent overflow taken place there.
Monitored: Overflow. These are red triangles with an exclamation point. These are locations that are either are currently overflowing or are no longer overflowing but are still in ‘overflow state’ as part of a larger multi-location “event”. Operators monitor this status and reduce it to yellow when they are satisfied that events have ended.
Monitored: Overflow in the last 48 hours: These are yellow triangles with an exclamation point. This are locations that are no longer overflowing, but have overflowed in the last 48 hours.
