This bin hold the water at the start of the siphon, it is constantly refilled by pumps from the lower reservoir.

Without a constant stream of water the siphon will run dry. Here are the pumps which move water from the lower reservoir to the upper reservoir to keep the system going. 

The siphon is three stories high within the hydraulics lab at the University of Melbourne. We built it alongside some of the pipes used years ago for large scale hydraulics measurements.

The top of the siphon which emerges in a lab, allowing us to connect our measurement sensors and data acquisition systems in a dry environment.

As part of the vacuum produced for FREO2, air is entrained into the water. Care must be taken in the technique used to introduce the air to the water.

Here a thin piece of pipe with holes in it is used to introduce the air into the water in a more homogeneous fashion. The bubbles being entrained can be clearly seen.

We designed this siphon with a clear section to facilitate aerator design. Here is a crude aerator and we can see the distruption it makes to the water flow.
