Gutters are used in Bentley SewerGEMS only to model the water which exceeds the capacity of in catch basin inlet and must flow through a surface gutter to the next catch basin. A Bentley SewerGEMS gutter can only receive water from a catch basin.

A conduit can refer to any prismatic channel or pipe that conveys flow. The cross section of a conduit must remain constant from one end to the next.

A channel refers to a channel that changes geometry from the upstream cross section to the downstream cross section. Channels can be used to model natural streams or swales which are not prismatic in cross section. Channels must have a cross section element at either end and properties are interpolated along the channel.

A uniform trapezoidal channel can either be modeled as a conduit with the shape defined in a conduit element or a channel with the shape defined as a property of the cross section elements at each end.

A lateral link can be used to model a surface (channel) or piped (conduit) tributary flow into the hydraulic network. The point at which this flow is injected into the network is modelled with location of a tap node. User should select a lateral instead of small diameter conduit when it is not important to compute full hydraulic results along the tributary link. User may option to use a lateral link and tap node to model this injected flow when the connection point is not an access hole with junction losses, or user does not wish to split the carrier pipe into two distinct hydraulic links.
