In the city of Cincinnati and other older large cities the sewers are what’s known as “Combined Sewer Systems”. The pipes and conduits for wastewater are shared with stormwater and it all goes to the city’s wastewater treatment plants. In Adams and Clermont counties all systems are instead “Separate Sewer Systems” where sanitary sewer systems or septic systems receive all of the piped household waste, but Stormwater is in entirely different pipes which lead directly into nearby streams with absolutely no treatment at all.
The only thing which should be flushed down a sink drain or toilet is bodily wastes, standard household soaps and detergents along with effluents from your laundry and dishwasher. Wipes, diapers, harsher chemicals than soap or acids should never be flushed down a toilet. These items either interrupt the waste breakdown process at the treatment plant, or in the case of materials other than toilet paper, have to be individually raked off of settling tanks at wastewater treatment plants.
The only thing which should go down a storm drain is rain water. Period.
