    Just wondering why the Thais make their gravity fed filters with holes in it instead of our method. Is there advantage in this way? I borrow a pic I got from google to illustrate...

    This design is typically what you can a multichamber up and down biofiltration. The multiple pipes you see are water transfer pipe which is required if the flow rate is strong so as not to cause water to drop too much coming from chamber to another. Personally I dont agree on this multiple chamber design and prefer the simpler one chamber horizontal river design which is easier to clean thoroughly and takes less footprint.
