sumpmark

Sumpmark is a term used in civil engineering and site documentation to denote a marker or symbol on drawings and maps that identifies the location and basic characteristics of a sump, or drainage pit, used to collect and manage liquids in a building, landscape, or infrastructure project. The concept functions as a coordinating reference within design, construction, and maintenance workflows.

In practice, a sumpmark is typically accompanied by an alphanumeric label (for example, SUMP-01) and linked to a data sheet or database containing key attributes such as invert depth, capacity, inlet and outlet connections, access requirements, and maintenance intervals. On plans, sumpmarks support coordination among architects, mechanical engineers, plumbers, and facilities staff by providing a consistent reference point for installation, inspection, and servicing.

Standardization of sumpmarks varies by region, company, and software ecosystem. There is no universal symbol or labeling convention, and practitioners often adopt regionally or company-specific conventions. Some implementations align sumpmarks with BIM or GIS workflows, enabling integration with spatial data, asset management systems, and drainage models.

Related concepts include general drainage markers, manholes, catch basins, and sump pumps. Sumpmarks may also appear in flood risk assessments and sustainability planning to document drainage infrastructure and ensure accessibility for routine maintenance.
