Engineered for external sanitary and stormwater connections, this Marley OGH drainage gully hopper is provided as a native Revit family component. The asset depicts a rounded, domed external overflow gully hopper with an upper access boss. Modeled with clean cylindrical and domed geometry, the fitting displays a raised top plate detailed with four corner standoffs and an elongated central drainage slot. The exterior surface transitions smoothly from a circular rim profile to a raised central collar, reflecting standard below-ground drainage accessories designed to catch discharge from downpipes and waste outlets while preventing ingress of debris.

The download is a 133 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Load the RFA component directly into your Revit MEP or architectural project. It can be positioned at ground level against perimeter footings, aligning with exterior soil and waste or stormwater riser stacks. The geometry includes clearly defined boundary edges for precise coordinate snapping in plan views, building elevations, and detailed groundworks section sheets.

Ideal for residential groundworks, commercial utility entries, and industrial stormwater detailing, this drainage accessory populates external utility interfaces. It integrates cleanly alongside exterior downspouts, inspection chambers, foul drainage stacks, and perimeter paving details across schematic design, planning submission sets, and technical civil drawing packages.
