A system capacity study conducted by Crespo Consulting - which sites Texas Commission on Environmental Quality standards - has indicated an increase in capacity is necessary to meet cur- rent and future water needs for City residents. The City's current water us- age records have also shown a need for additional capacity. With these facts in mind, the City is considering a $16.5 million TRA plant expansion package which may be approved by voters later this year. According to Carol Reed, Public Utili- ties Director, the expansion would ef- fectively increase water production capacity from a firm capacity of six million gallons daily to a firm capacity of 12 million gallons daily and address several key concerns at the plant sim- ultaneously. "The primary, overriding need for ex- pansion of the TRA water plant is to increase its production capacity," Reed said. "However, there are a number of other issues at the plant that need to be addressed, including filters, the removal of nitrates from our water, chlorine contact time in our existing clearwell, the age and condition of the high service pump station, and the electrical system that supplies the plan. "W e are currently looking at a plant expansion which would cost approxi- mately $16.5 million to complete and would address all of these needs. We have studied our water system and the needs of our residents, and we feel this plan is the best way to bring our plant's capacity to the needed level." Getting started Given voter approval, which would come following an election in Novem- ber of this year, the plan to make ex- pansions at the TRA plant would have to meet TCEQ approval. The TCEQ approval process, Reed said, would take a minimum of 90 days as the essence of the expansion goes beyond making basic improvements. "If we move forward with the plant ex- pansion, we would need to get TCEQ approval because the changes we're suggesting go beyond normal im- provements," she said. "We're not just updating one or more compo- nents to stay at the same level of production, but changing our capacity and altering the output of the entire plant. "Basically, the type of changes being made are completely different than updates or improvements, so the design changes that need to be com- pleted will take a few months before we can even consider bidding out the project." After the T C E Q a p p r o v a l and d e s i g n p r o c e s s , Reed said the earliest she could see construction beginning at the plant would be March 2012. "If we get approval from our voters and work with TCEQ on mapping out the expansion process, we could begin this multi-year process around March of next year," Reed said. "At this point, I feel like a time period of two to three years might be a realistic goal for completing the expansion. "We wanted to have the expansion completely paid off over the next eight years, and I can say with confi- dence that Huntsville would benefit from the expansion long before that time has passed." Specific alterations From the pumps that bring water from the Trinity River into the TRA plant to the high service pump station that sends water to the City for use, sev- eral key changes will be made as part of the expansion process. "To start from the beginning of the water treatment process, we would first begin the expansion by adding another intake pump to our existing set of three pumps," Reed said. "Our 30" raw water pipeline, which trans- ports water from the Trinity River to the plant, would also be improved. "In 1998, the first 900 feet of the pipe- line was replaced with a higher pres- sure rated 36" pipe, while the rest of the pipe was not replaced. With this expansion, an additional 2,000 feet of pipe would be upgraded in the same $I would expect [this expansion of the TRA water plant] to carry us well into the future."

"There would be a two-fold purpose in expanding our current filter system," she said. "First, the new filters would be used to increase our capacity to 12 MGD, but also, they would filter nitrates from our water, which is a current state requirement. "We would accomplish this by adding two filters to decrease turbid- ity - basically, dirt levels in our water - and two filters to address nitrate removal." Next on the list of expansion items would be the plant's clearwell, a large, circular container capable of holding 1.2 million gallons of water while it is being treated with chlorine. "We don't plan on tearing down our existing clearwell," Reed said. "Instead, we're going to add another clearwell which is larger than our current one. Our goal is to have 12 million gallons daily going out the door, and having the second clearwell will play a critical part in having that water ready for our citizens." The final step in the expansion process would be to update the high service pump station, which pumps the water from the plant to the residents of Huntsville. "We already have three high service pumps in place, and the ex- pansion would require adding a fourth," Reed said. "With that change made, we will have addressed all of the major plant components and reached a level of production of 12 million gal- lons daily." Looking to the future Keith Bass, who has worked at the TRA water plant for over 30 years, spent much of his time there as the plant's manager. Now, as the O&M Chief of Southern Region Support Services with the plant, Bass views the expansion as a necessary step to bring Huntsville back to a safe water production level comparable to similar cities. "Having worked at the plant for a significant number of years, I've seen the demand increase," Bass said. "From my perspective, I feel like this expansion is necessary, because we get so close to not being able to meet the demands of the citizens. "I honestly wouldn't have guessed we could make it this long with- out expansion, and if we don't complete the expansion soon, it's my opinion that we would be putting the city [at risk]." With the expansion completed, Bass said the City would more than likely have the capacity necessary to support its citizens needs for decades to come. "Right now, we have a firm capacity of six million gallons daily, and this expansion would double that to a 12 million gallons daily firm capacity," he said. "I would expect that level of production to carry us well into the future." 0 -+ 1 ,- 1 G -1 G 8 (0 *,# , <%,# -,- , 1 1 ,-, ,# -9 1 2 , H ,;12H=1 ,,, ,,-,,,, ,,# 0 -- - 1 # 0 9 ,+ (,9 ,8( ,,9 # 1 - 9 ,, 9 # (,,-/# F # $B ,,,F F ,,,-, ,,,G 3 #$:- ,-F -, ,,,#3 (1 , ,# $9 8(, G ,,9 - ,,,,9 --,9 -,3*,I ,A 1 ,8 # $7 9 ,,9 , J 9 ,,,, ,,,,,, ,# $, ,#3 M ^ IN � T� S U M M E FZ FILIMFESTIVAL. 5 LD TOWN TtlEAT E - DOWNTOWN "Off be C�f The Yearls 10 BeWl 1 �.
