Collection system

Nine lift stations and a treatment works on DNP3, deliberately split across two Litmus Edges managed from one Litmus Edge Manager.

v0.1.0

How it works

A water and wastewater collection system: eight lift stations plus the treatment works, 9 devices and 274 tags over DNP3.

The fleet is split across two Litmus Edges managed from one Litmus Edge Manager, and that is the point rather than an accident. LEM manages Edges rather than devices, so a fleet of RTUs behind a single Edge is invisible to it. A shared lift station twin model is authored in the LEM registry and pushed to both districts, and drift between them is reported.

The money moments are pump efficiency degrading before anything alarms, a sanitary sewer overflow seen while it can still be prevented, and the NPDES report assembled from what was actually measured.
