Abstract
This handbook is an interim version of a source document for individuals responsible for improving the performance of existing surface water treatment plants using conventional and direct filtration unit processes to achieve compliance with the Surface Water Treatment Rule (SWTR). It includes an evaluation technique to identify causes of poor plant performance and to assess the capability of existing facilities for achieving compliance, the Comprehensive Performance Evaluation (CPE). It also describes implementation of the Composite Correction Program (CCP) phase, which details methods of optimizing existing facilities without major capital improvements. Procedures to address design, operation, maintenance, and administrative factors limiting performance are outlined. The overall top ranking factors limiting performance that were identified at the 21 CPEs in 6 states are discussed and the conclusions based on these observations are presented.
