Target outcome · Zero storm-related effluent excursions. Biological recovery cut from 2 to 5 days down to under 2 days.
Business problem
During peak flow events, the biological treatment process is stressed by hydraulic surge, temperature shock, and shifting pollutant load. Operators manually adjust clarifier operation, return activated sludge rates, aeration response, and storm-mode transitions. Poor coordination leads to clarifier blowouts, sludge loss, and effluent excursions that risk permit violations and take days to recover.
What it does
Five specialised agents coordinate the complete biological and physical treatment response during wet-weather events, from storm mode activation through to biological recovery.
5-agent team
- Hydraulic Impact Expert — assesses how influent surge is affecting physical treatment units
- Biological State Expert — monitors process stress and recovery indicators
- Clarifier Operator — watches sludge blanket, overflow rate, and effluent turbidity from clarifiers
- Process Mode Orchestrator — coordinates storm mode transitions, clarifier and RAS response, and recovery sequencing
- Compliance Guardian — validates every action against discharge permit envelope and biological recovery indicators
What the team handles
Handles
Storm mode transitions, clarifier hydraulic management, RAS rate adjustment, storm-mode aeration profiles, recovery mode coordination, inter-team coordination with Storm Flow and Chemical Dosing teams.
Does not handle
Hydraulic routing upstream (Storm Flow Team), chemical dose (Chemical Dosing Team), regulatory notification, biological process design (SRT, MLSS targets).
Humans retain authority over
Envelope adjustments, storm severity reclassification, emergency bypass declarations.

Scoping questions
Expect these questions in a first scoping conversation. They signal engineering discipline and help narrow the template to your specific site context.
- What is the history of storm-related effluent excursions at the site?
- What is the current storm-mode SOP and biological recovery protocol?
- How is regulator engagement structured, and what is their expected posture on autonomous action during wet weather?
- Are clarifier, RAS, and aeration setpoints writable via SCADA?
- What biological state indicators are instrumented?
