In-sewer stability of illicit drug biomarkers has been evaluated by several reactor-based studies, but less has beendone in sewer pipes. Experiments conducted in sewer pipes have advantages over lab-scale reactors in providing more realisticbiomarker stability due to theflow and biological dynamics. This study assessed the transportation and transformation of sevenillicit drug biomarker compounds in a pilot-scale rising main and a gravity sewer pipe. Biomarkers presented diverse stabilitypatterns in the pilot sewers, based on which a drug transformation model was calibrated. This model was subsequently validatedusing transformation data sets from the literature, aiming to demonstrate the predictability of the pilot-based transformationcoefficients …
