Reservoir Outlet Structure Diagram - Engineering Illustration #235934 (License: Personal Use)

This black-and-white engineering diagram depicts a reservoir with a horizontal outlet pipe embedded in an earthen embankment, allowing controlled water release. The labeled components-“OUTLET” and “RESERVOIR”-highlight key structural elements, while the sloped fill and groundwater table suggest subsurface flow considerations. The illustration style is typical of early 20th-century civil engineering manuals.

Used in educational materials, civil engineering textbooks, or municipal water infrastructure documentation to explain reservoir outflow mechanisms; matches user intent for learning or designing small-scale water retention systems.
