Abstract
Designing and Integrating Toronto's Largest Sanitary/Combined Sewer Overflow Pumping StationAbstractThe City of Toronto has launched the largest and most significant stormwater management program in its history to prevent combined sewer overflows (CSO) from entering the waterways. The program includes over 30 km of new tunnels and storage shafts, a new pumping station, a Landform Project with a High-Rate Treatment Facility, and a new treatment plant outfall to Lake Ontario. The new Integrated Pumping Station (IPS) will replace two aging sanitary pumping stations and add a Wet Weather Flow (WWF) pumping system to pump Combined Sewer Overflows (CSOs) to a new high-rate treatment facility. The program will greatly improve the water quality in the Lower Don River, Taylor-Massey Creek and along Toronto’s Inner Harbour by treating CSOs and keeping them out of the waterways. This paper will focus on the design aspects of the new Integrated Pumping Station, highlighting some of the key construction considerations necessary to maintain plant operations throughout construction.The City of Toronto has launched the largest and most significant stormwater management program in its history to prevent combined sewer overflows from entering its waterways.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
