Tezu OpHmization Proeram: Charter Year Successes for a MediSm-Sized System Sam B. Oswood: Depury General Manager: Brow! CountY Water Improvement District 91 - Brownwood, Texas, USA Michael G. Momson, P.E., DEE: Principal: Freese and Nichols, Inc., Fort Worth, Texas, USA ABSTRACT: This paper present5 the experience of the Brovm County Water Improvement District R11 (gC WID) tlvough its p articipation in che Texas Optimization Program The District, lo cated in Brownwood, Texas has a service population of 36,000, providing treated water to the communities of Brovmwood, Bangs and the Brookesmith Water Supply Corporation. In this charter year of the state's optimizarion*~program, the BCWID has achieved the recognirion 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 similaz to the AWWA Parhlership for Safe Water Program. The purpose ofthe state-implemented program is to maximize the performance of an existing 'treatment plant by addressing the factors which limit iis performance. The goal of the program is to reduce the risk of waterbome diseues by reducing the number of pathogenic organisms that could pass through a treatment plant. Through the optimization of the BC WID treaiment plant's performance, the District realized a cost savings in chemicals while improving plant performance. This paper presents a review ofthe optimizarion process from parrncipation in the voluntary Texas Urility Co-op Program for training 6Y the state of Texas in the Comprehensive Performance Evaluarion (CPE) approach. This process involves the actual CPE study of the plant and of the approach to modifying the four major conh-ibuting areas which impact plant performance (operations, design, adminisiration and maintenance) in ordec to oprimize treatrnent plant performance to meet the Tesas Oprimization Program's goals. Teaas Optimization Proeram's Iiecoenition Criteria i. Filtered Water Turbidity less than or equal to 0.1 NN ia 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 NTIJ• backv✓ash 4. Filtered Water Turbidity less than or equal to 0.3 IVT[J durinB Post- turbidity spikes. 5. Recovery to less than or equal to 0.1 NTU within 30 minutes.
