A liquid quality system for removing particulates from liquid (e.g., storm-water runoff). The system can include tubular portion (e.g., a manhole). The tubular portion has an inlet and an outlet. The system includes liquid quality device. The liquid quality device includes a partitioning portion. The partitioning portion has a first region including a funnel shape with a sump inlet aperture. The partitioning portion also has a second region including a sump outlet aperture and optionally a sump access aperture. A sump region is located between a base portion and the partitioning portion, wherein a flow of the liquid travels from the inlet in the tubular portion, into the funnel, through the sump inlet aperture, into the sump region, through the sump outlet aperture, and out the outlet of the tubular portion. At least one drag-inducing portion is positioned proximate the tubular portion in the sump region and projecting inwardly towards a central axis of the sump region.
