including screening and macerating solids,,(teeth), seperating solids from liquids, (side streams in the body leading to liver, kidneys, bladder, etc..), and temperature (98.6 in both digesters and humans ), and PH balance similar in digesters and humans...finally waste effluent in the plant is chlorinated and transferred to receiving waters...In humans urine is sterile and is transferred back to the sewer...There are many more similarities, too many to recount here,,,such as bacterial oxidation of solids. Also when digesters in the plant get "upset" they are dosed with lime or alkalines to raise PH levels....any way, my question actually is, is this all coincidental, or did the first waste water engineers model the plant process directly from the human body???....anybody know??? thx. in advice for answer..

There are similarities, but not as many as you recount. BTW, urine is NOT sterile. The main feature of the sewage treatment plant is the conversion of soluble organic matter to solids by the use of the aerobic reactor.
