The Short Answer

Economics and physics. Rubbish isn't a fluid. Sewage and water mostly are, with floaty or clumpy bits in the former. So you can use gravity and pumps to quite inexpensively make them "flow" from the source to the destination. Further, rubbish is very much irregularly shaped, with sticks and poles and things that can't bend at all around corners. So even if you could somehow construct some expensive technology that allowed you to convey your trash through them, your pipes would get jammed up at every curve or bend all of the time.
