The innovative treatment process used at Brown County WID's 10 MGD <br />treatment plant employs tube settlers in the clarification basins, which allow <br />treatment at a higher rate than a conventional basin of comparable size by <br />shortening the settling distance and improving flow distribution. The tube settlers <br />provide enhanced turbidity removal. Clarification is preceded by rapid mixing and <br />flocculation and followed by filtration in dual media gravity filters with air/water <br />backwash. Operations are simplified by splitting influent flow evenly between filters <br />in service and utilizing the increased head loss concept to signal backwash <br />requirements, rather than using rate of flow controllers for filters <br /> <br />A site selection analysis was made to determine that the site near the original facility <br />was preferable to other locations on the north and east sides of Brownwood. Freese <br />and Nichols also administered construction for the project, which was completed in <br />1986 at a cost of approximately $3.7 million. <br /> <br />Following an evaluation of the plant conducted in 1991, Freese and Nichols <br />designed improvements to the plant and provided construction management <br />seIVices. <br /> <br />Currently, Freese and Nichols contracted to conduct an uprating evaluation for the <br />water treatment plant. The purpose of the evaluation is to determine if the plant can <br />be rated at a higher capacity (20% increase) while still meeting SWDA requirements. <br /> <br /> <br /> <br />.... <br /> <br />~PSU <br /> <br /> <br />On Wednesday, Moy 13, 1998 the <br />District was honored by the TNRCC and <br />received recognition os one of the first of <br />only two water treatment facilities in the <br />state to achieve the high quality <br />standards under the Water Optimization <br />Program. The quality of water being <br />produced equates to five times better <br />than normal standards. The District's <br />board General Manager, Harry Miller, <br />Assistant General Manager, Sam <br />Oswood ond treatment stoff were singled <br />out for their efforts in providing the <br />highest quality water for Brown County. <br />The District received this prestigious <br />award for the second time on October <br />14, 1998, making it the only water <br />district in the state to hove received the <br />award twice. <br /> <br />oetic <br /> <br />(:~.\ <br /> <br />j/O( <br /> <br />A{ <br /> <br />C' <br /> <br />(I <br /> <br />o <br />
