This document is a technical diagram showing an underground water distribution or treatment system consisting of three large cylindrical concrete tanks arranged in series. The image illustrates the flow direction of liquid through the system from left to right, with red arrows indicating the primary flow path. Two vertical measurements of 30 inches are marked on the left and center portions of the diagram, indicating distances between connection points or tank dimensions.

The system includes mechanical components such as hand-operated valves with level indicators (shown in teal/green), pressure gauges, and interconnecting piping with various fittings and control mechanisms. The annotation specifies the precise directional orientation that the hand wheel valve must face upon installation. Each tank sits on a gravel bed foundation within what appears to be a concrete vault or underground chamber. The diagram provides detailed installation guidance for proper assembly and operational configuration of this multi-tank water handling system, likely used for municipal water treatment, storage, or distribution purposes.
