SQIDEP Myth: Are Hydraulic & Treatment Flowrates Part of the Assessment?

This claim is incorrect and hydraulics & treatment flowrates are key criteria in SQIDEP’s assessment requirements.

SQIDEP (Page 32, Table 3 — Minimum data and qualifying event requirements for assessment) states that at least 2 events should exceed 75% of the design water quality volume/TFR and 1 event must exceed 100% of the TFR. Flowrates (hydrographs) must be submitted to satisfy this requirement.
