Hello, I just read the SALES PITCH!!! Look, this person is not telling us anything NEW! I also like the part about the bio material emitting infra red something or other. #1 Why use a pump in the drainage area? The laws of physics indicate that water will naturaly FLOW into the drainage pipes ( gravity feed)! #2 no sediment chamber??? well here to he is a little wrong, as the sediments flow over and through the bio material, they will clog the bio material, thus suffocateing the good bacteria from the oxygen that they need to live. Ceramic bio material is fine, so are lava rocks, but with modern times there are better materials like, PLASTICS which are lighter and cheaper! Also this person mentions BAD WATER??? well, where would this bad water be ????
It is very simple, the act of water softly running over and through pourus material will naturaly provoke the growth of the bacteria that we want. and by the water running over and through a material, this will naturaly cause a disturbence in the flow of water thus oxygenating the water! so with these STAND PIPES??? do not worry.

Hi ayranjim, Thanks for the response. However, I still don't understand the working of a standpipe. Does it mean that in a settlemnt chamber that has a standpipe, there is also another waste outlet for flushing and both these are then connected to the main flush line? Sorry, this might seem like a silly question but I am new. So please excuse the ignorance. Much obliged.
