Operator Need to Know

The Need-to-Know can be simply defined as that knowledge that an operator or those desiring to be operators must possess to be prepared for the duties and challenges he will face as an operator. These Need-to-Know documents were developed to provide those individuals with a listing of subject matter and understanding areas for each operator classification of water treatment, distribution systems, wastewater treatment and collection systems available in Tennessee.
