About this asset

Floor-hosted dual-outlet rainwater sump Revit family modelled with a flanged rectangular catch basin and dual bottom pipe connections for drainage. This drainage component features a rectangular sump basin bordered by an integrated perimeter flange for flush floor or slab seating. Inside the open catch box, the base incorporates two circular cylindrical outlets arranged side by side. One outlet functions as a low-level drain while the adjacent collar forms a raised overflow riser or dual downpipe discharge point. The exterior body reveals clean orthogonal geometry designed to drop directly into floor penetrations or exterior slab cutouts, presenting a neutral grey metallic or composite surface finish.

The download is a 276 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.

Designed for Revit workflows, this floor-hosted plumbing family inserts directly into floor slabs or roof deck hosts. Users can align the rim to finished surface levels, configure subcategory visibility in plan and section views, and coordinate pipework connections to MEP sanitary or stormwater drainage systems. The geometry ensures precise penetrations in structural floor layouts without excessive polygon overhead.

Engineered for stormwater management and architectural MEP coordination, this rainwater sump suits commercial, industrial, and multi-residential projects. It integrates into exterior balconies, plant rooms, podium decks, car parks, and utility drainage zones. Plumbing designers and BIM coordinators commonly search for floor sump, rainwater collection box, scupper pit, and drainage catch pit families to model reliable rainwater discharge and prevent surface water ponding across large concrete decks.
