About this asset

Designed with a ribbed structural shell, this sewage ejector basin Revit family models below-grade wastewater storage for MEP coordination. The model depicts a tall, vertical cylindrical sump basin finished in uniform mid-grey, characteristic of heavy-duty molded polyethylene or composite drainage assemblies. Its cylindrical body features pronounced external structural ribs spaced evenly down the entire shaft to resist soil pressure in sub-slab installations. The top is sealed with a circular domed service cover designed for inspection and piping penetrations, while the base terminates in an integrated lip ring for stable anchoring within floor slabs or excavated pit sumps.

The download is a 266 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 this RFA component directly into your Revit project or template to establish below-grade drainage infrastructure. In MEP project views, position the ejector pit below lowest-level slabs or within designated utility sumps, aligning vertical datums with architectural foundations. Modelers can route incoming waste stacks and vent piping directly to the unit, verifying clash avoidance against footings and structural grade beams in federated Navisworks or Revit coordination models.

Engineered for sub-grade drainage layouts, this sump vessel suits residential basements, commercial parkades, hospitality utility wings, and light industrial plant rooms. It integrates seamlessly into schematic plumbing risers alongside lift stations, submersible pumps, backwater valves, and wastewater discharge pipework. Plumbing designers and BIM managers searching for ribbed ejector pits, sump basins, or below-slab drainage equipment can deploy this family during early spatial coordination through to detailed MEP construction documentation.
