This model is based...

... in which air regulation is achieved through two pipes which dip into the surfaceof the headwater. Oneof these dip pipes admits air to the crown of the siphon passage, and the other admits air at the crest. This form of air admission produces good dispersion of air into the water flowing through the siphon...
