I think that the replies to this thread are getting away from the original question.
My understanding of the situation is this: When the water flow is adequate the Banki can be run full time (no problem), but during dry spells the water flow is not adequate so a scheme was designed to store water in a 500 gallon tank which would provide intermittent full flow to run the Banki. The question is how to make this work. Initial attempt with a flexible pipe running into the side of the header tank did not produce intermittent full flow, but constant low flow. I dont have an answer - it sounds a bit like the solution could be along the same lines as the flushing of a toilet. The key thing is to have two distinct states - no flow and full flow. If this could be done with a periodically fired flapper valve then that would work, but maybe there is some way to make a syphon system work where there is no valve. Any ideas?
