Four cylindrical tanks are stacked vertically against a cloudy night sky

Four cylindrical tanks are stacked vertically against a cloudy night sky. Each tank has a conical bottom and a corrugated surface. Metal scaffolding supports the tanks, with glimpses of red machinery or fixtures visible. A concrete or paved surface stretches to the right, while a staircase leading up to the tanks is seen in the foreground. The image is dimly lit, casting long shadows.
