The Walhalla Water Department understands the fundamental need to make efficient use of the limited and valuable water resources under its stewardship in order to protect the public's health and safety and environmental integrity. The purpose of this chapter is to establish a plan and procedures for managing water demand and evaluating supply options before and during a drought-related water shortage. The intent is to satisfy the requirements of the Drought Response Act of 2000 (S.C. Code Ann. § 49-23-10, et seq., as amended), with the goal of achieving the greatest public benefit from domestic water use, sanitation and fire protection and to provide water for other purposes in an equitable manner. Therefore, the Walhalla Water Department has adopted this Drought Management Plan and Drought Response Regulations that provide the policies and the authority to fulfill this obligation. The Drought Management Plan (Article II) outlines the framework by which Walhalla Water Department will internally prepare for water shortages. The regulations (Article III) provide the regulations by which the Walhalla Water Department will manage and control its customer water usage during various levels of a drought.
