Disinfection detention time, one of the key factors in determining compliance with the Surface Water Treatment Rule, was evaluated in this study to determine (1) whether typical water plant basins can be modified with intrabasin baffles to improve detention time and (2) whether model basins can simulate full‐scale systems. The results of the work show that both a rectangular and a circular basin can be modeled quite accurately by small‐scale basins. Tracer tests showed that T 10 detention time can be improved with simple intrabasin baffle walls to approximately 60 percent of theoretical detention time.
