S.C. Code Ann. § 6-11-110: Commissioners in certain counties may furnish services outside district.

In counties having a population between forty-one thousand and forty-three thousand according to the 1950 census, boards of commissioners of such districts may provide water, sewerage and fire protection to citizens outside of such districts in those counties or adjacent counties and charge such rates therefor as they may fix, which may be more but not less than the rates charged citizens of such districts for similar services and facilities.
