Primary_Tank_drawing_2.pdf

The image is a detailed engineering drawing from Wright-Pierce, a civil engineering firm, focused on a primary settling tank plan and section. The technical blueprint includes a circular tank design with radial structural elements, accompanying elevation views, and specific dimensional annotations. The document appears to be a technical schematic for a water or wastewater treatment facility infrastructure component, showing precise architectural and engineering specifications for a primary settling tank structure. The drawing includes multiple views - a top-down circular tank plan, a side elevation section, and detailed measurement markings across the design. The document bears official municipal engineering stamps and contains multiple technical grid and measurement references typical of professional civil infrastructure design documents.
