In all technical sense, it can be treated as a large septic tank that is functioning correctly and does not leak or is discharging sanitary sewage to the environment in the interim! Not like the +40% of failing septic tanks in the area now.
All pipes are buried underground; I don't know how one can say "I can't believe my eyes" as you can't.
Remember LORCO and ALMU are the sanitary sewer experts, "They Know Sewers"!
As for health concerns, the sewerage is in the pipe is better that raw sanitary sewerage discharged to the drainage swale in front of your home. Do you know the many deadly diseases that can be contracted from RAW SANITARY SEWERAGE exposure???
God Bless OhioEPA, LORCO and ALMU, they are the real HEROS in this epic story! As well as President Obama, Federal funding putting Ohioans back to work!
