On April 25, 1980, in compliance with the provisions of Chapter 88 of Title 11, Code of Alabama, 1975, Limestone County Water Authority was awarded the Certificate of Incorporation, creating the initial Limestone County Water Authority with three directors, B. Turner, T. Smith, Jr. and I. Warren. On December 10, 1997, the Articles of Incorporation of the Limestone County Water Authority were amended to change the name to Limestone County Water & Sewer Authority. Numerous amendments to the original Article of Incorporation give a concise, legal description of the areas to be served with water and sewer services.
Prior to 1982, the independent systems of South Limestone, East Limestone, Fort Hampton, and North Limestone were under the direct management of the Limestone County Commission. In October 1982, the Commission turned over full authority for operations of all four systems to LCWSA.

The South Limestone Water and Fire Protection Authority, another independent system, was consolidated into LCW&SA on March 25, 1986. In May of 1998, we took over the water and sewer service for the Elkmont Rural Village.
The growth of the system has been phenomenal, as evidenced by the fact that as of July 1985 LCWSA was billing 4,200 customers and presently we are billing over 16,381 customers. Currently LCW&SA has over 1100 miles of water mains with approximately 1,224 fire hydrants.
