Texas Optimization Program: Charter Year Successes for a Medium-Sized System Sam B. Oswood: Deputy General Manager: BroWI'). COtUlty Water Improvement District #1 - Brownwood, Texas, USA Michael G. Morrison, P.E., DEE: Principal: Freese and Nichols, Inc., Fort Worth, Texas, USA ABSTRACT: This paper presents the experience of the Brown Co'tUlty Water Improvement District #1 (BCWID) through its participation in the Texas Optimization Program The District, located in Brownwood, Texas has a service population of36,000, providing treated water to the communities of Brown wood, Bangs and the Brookesmith Water Supply Corporation. In this charter year of the state's optimizatio~'program, the BCWID has ~chieved the recognition criteria as set for the Texas Optimization Program. The District is one of the first water systems in the state of Texas to be recognized under this program, which is similar to the A WW A Partnership for Safe Water Program. The purpose of the state-implemented program is to maximize the performance of an existing treatment plant by addressing the factors which limit its performance. The goal of the program is to reduce the risk of waterborne diseases by reducing the number of pathogenic l organisms that could pass through a treatment plant. Through the optimization of the BCWID treatment plant's performance, the District realized a cost savings in chemicals while improving plant performance. This paper presents areview of the optimization process from participation in the voluntary Texas Utility Co-op Progi~ for training by the state of Texas in the Comprehensive Performance Evaluation (CPE) approach. This process involves the actual CPE study of the plant and of the approach to modifying the four major contributing areas wl}ich impact plant performance (operations, design, administration and maintenance) in order to optimize treatment plant performance to meet the Texas Optimization Program's goals. Texas Optimization Program's Recognition Criteria 1. Filtered Water Turbidity less than or equal to 0.1 NTU in 90% of the readings for each filter. 2. Filtered Water Turbidity less than or equal to 0.1 NTU in 95% of the readings for all filters. 3. No Filtered Water Turbidity greater than 0.5 NTU. 4. Filtered Water Turbidity less than or equal to 0.3 NTU during post-backwash turbidity spikes. 5. Recovery to less than or equal to 0.1 NTU within 30 minutes.
