Full Description

From March to November 2001, two-day comprehensive filter plant performance evaluations were completed for forty-five small system rapid sand filter surface water treatment plants (WTP). These evaluations were based on a format adapted from the EPA Comprehensive Performance Evaluation (CPE) program. This program identified numerous design deficiencies that had the potential to limit treatment plant performance. There were several design issues common to the majority of plants reviewed and could have easily be corrected through better design or construction of the plants. In most instances, these limitations could also be corrected in existing WTPs with minor modifications. Many of the design deficiencies seen in the small WTPs are also applicable to larger WTPs. These limitations were seen in WTPs designed both by small local firms and large national and international firms. While limitations were identified in this proactive approach, the plants evaluated were operating with no known health problems. The purpose of these evaluations was to review existing plant operations and to suggest improvements to enhance the performance of water systems serving less than 10,000 people. Filter Plant Performance Evaluations (FPPEs) were performed on 45 small system surface water treatment plants that utilized rapid-rate filtration. FPPEs were accomplished by reviewing historical turbidity data, conducting site visits and evaluating the design, operation, and maintenance of each water treatment plant. Each visit included a comprehensive review of the facilities, from the intake of the water supply to the entry point of the distribution system. Includes tables, figures.
