S.C. Code Ann. § 58-7-25: Right to repurchase unused condemned property.

(A) If the property, or any portion of it, condemned by a corporation engaged in the business of supplying sewerage service, pursuant to the provisions of this chapter, is not used for the purpose for which it was condemned within a five-year period from the date it was condemned, the former owner has the right to repurchase the property from the corporation upon payment of the original purchase price.

(B) Unless the former owner exercises his right to repurchase this property within a period of one year from the expiration of the five-year period as provided in subsection (A), the right to repurchase ceases when the corporation gives the former owner ninety days' notice that the right will expire at the end of the ninety-day period.
