S.C. Code § 6-15-100
If the notice or notices prescribed by Section 6-15-90 shall have been given and any hearing requested pursuant thereto shall have been held all connection or tapping fees, sewer service charges and other charges imposed by the governing body following that procedure under authority of this chapter and not paid when due and payable, shall constitute a lien upon the real estate to which the sewage service concerned relates so long as the fees or charges remain unpaid. In addition to such other rights and remedies as may be available to the governing body in law or in equity for the collection of such fees and charges, the lien may be enforced by the governing body in the same manner and fashion as the lien of property taxes on real estate.
