What is sewage or wastewater?
Sewage or wastewater is water that goes down drains inside homes or businesses. The wastewater portion of your bill pays the costs associated with cleaning wastewater andreturning it to the environment. Storm water is collected in a separate drainage system operated by the City of Charleston Public Service Department.. Charleston Water System acts as a billing agent to collect storm water fees on water/sewer bills, but does not operate the storm water system; all storm water fee revenue transferred to the City.
