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. ## Claims ### Claim 1 A system for removing particulates from liquid, wherein the system comprises: a base portion; a tubular portion extending upwardly from the base portion, wherein the tubular portion comprises an inlet and an outlet; a liquid quality device located above the base portion, wherein the liquid quality device includes a partitioning portion comprising: a first region comprising a funnel and a sump inlet aperture, wherein the first region is arranged to receive a flow of the liquid from the inlet of the tubular portion; and a second region comprising a sump outlet aperture, wherein the second region is arranged to transfer a flow of the liquid to the outlet of the tubular portion; a sump region located between the 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; and a plurality of drag-inducing portions positioned proximate the tubular portion in the sump region and projecting inwardly towards a central axis of the sump region; wherein the plurality of drag-inducing portions comprise: a first drag-inducing portion; a second drag-inducing portion located below the first drag-inducing portion; and a third drag-inducing portion located below the second drag-inducing portion. ### Claim 2 (depends on 1) The system of claim 1, further comprising a weir extending upwardly from the partitioning portion and positioned between the first region and the second region. ### Claim 3 (depends on 1) The system of claim 1, wherein the plurality of drag-inducing portions are attached to a supporting portion, which is positioned proximate the tubular portion in the sump region. ### Claim 4 (depends on 3) The system of claim 3, further comprising a plurality of supporting portions, each being positioned proximate the tubular portion in the sump region and having attached the respective plurality of drag-inducing portions. ### Claim 5 (depends on 4) The system of claim 4, wherein each of the plurality of supporting portions are positioned equidistantly around a perimeter of the tubular portion from the other plurality of supporting portions. ### Claim 6 (depends on 5) The system of claim 5, wherein the plurality of supporting portions comprise: a first supporting portion; a second supporting portion; a third supporting portion; and a fourth supporting portion. ### Claim 7 (depends on 6) The system of claim 6, wherein the first drag-inducing portion and second drag-inducing portion of each the first supporting portion and third supporting portion respectively have a different orientation than the first drag-inducing portion and second drag-inducing portion of each the second supporting portion and fourth supporting portion. ### Claim 8 (depends on 3) The system of claim 3, wherein the supporting portion is integrated with the partitioning portion. ### Claim 9 (depends on 1) The system of claim 1, wherein the plurality of drag-inducing portion each comprises a substantially triangular shape. ### Claim 10 A system for removing particulates from liquid and inducing drag in a liquid flow, wherein the system is configured for insertion into a manhole thereby creating a sump region below the system, wherein the system comprises: a partitioning portion positioned above the sump region, wherein the partitioning portion includes: a first region comprising a funnel and a sump inlet aperture; and a second region comprising a sump outlet aperture; and a plurality of drag-inducing portions positioned proximate a sidewall of the manhole in the sump region and projecting inwardly towards a central axis of the sump region; wherein the plurality of drag-inducing portions comprise: a first drag-inducing portion; a second drag-inducing portion located below the first drag-inducing portion; and a third drag-inducing portion located below the second drag-inducing portion; a first supporting portion; a second supporting portion; a third supporting portion; and a fourth supporting portion; wherein each the first supporting portion, second supporting portion, third supporting portion and fourth supporting portion are positioned proximate to the sidewall of the manhole in the sump region and comprise: the first drag-inducing portion; the second drag-inducing portion; and the third drag-inducing portion. ### Claim 11 (depends on 10) The system of claim 10, further comprising: a weir extending upwardly from the partitioning portion and positioned between the first region from the second region.
