Quality Control

Because sensor data is noisy.

Real-Time Forecasting

Ingest public radar products, process, and incorporate into hydraulic models and recommendation engine

Control Engine

Even after QA/QC process, there are still 100s of data points to synthesize and transform into actionable information.

Existing Challenges

Without coordination, actions can lead to unforeseen consequences throughout the network.

 

Take this toy example with 3 upstream control points and a downstream WWTP.

Existing Challenges

As we use storage structures in the network to mitigate CSOs and reduce wet weather peaks at the outlet of the network, the structures fill up and experience stress.

Existing Challenges

If we release stored water without information from the entire system, it could actually compound wet-weather effects downstream, or cause CSOs.

Existing Challenges

Alternatively, managing downstream objectives through the release from some assets could result in upstream flooding in others.

Existing Challenges

These problems require a structured framework to release upstream volumes to meet downstream objectives.

Implementation

What if we did things differently? Coordinating actions at the system level?

 

 

Implementation

Implementation

Initially during a rain event, holding water upstream creates capacity downstream.

 

 

Implementation

As storages fill, stress increases. We seek to distribute downstream capacity among upstream storages based on their stress.

 

 

Implementation

When downstream is above a desired set point, the algorithm discourages releases from upstream.

 

 

Implementation

Repeating this process continuously throughout a wet-weather event will nudge downstream to its objective, while utilizing upstream storage maximally

 

 

Decision Dashboard

No action without effective communication of recommendations to operators.

Decision Dashboard shows real-time and historical recommendations alongside system data like flow and levels.
