_ __ <br />I-2 <br />• <br />BO DS, 12 mg/1 TSS and 2 mg/1 NH3-N required for the Clear Creek <br />watershed. Using the original construction drawings and the <br />latest State design criteria, the capacity of each individual <br />treatment unit was calculated. As shown in Table 1, the plant <br />has an average capacity of only about 80,000 gallons per day <br />(gpd) assuming a peak to average flow ratio of 4. This capacity <br />is limited by the chlorine contact basin. The next most critical <br />unit is the final clarifier which limits the capacity to 120,000 <br />gpd. Higher peak flows would result in less capacity. <br />A discussion with the Texas Department of Water Resources <br />District 7 (Deer Park) personnel generally confirmed the evalu- <br />• ation. The plant is currently treating an average flow of <br />approximately 210,000 gpd and is not meeting the effluent stan- <br />dards. Thus, either a major modifica~ <br />diversion of the flow to the La Porte <br />necessary to treat the projected 1986 <br />290,000 gpd. <br />Since the existing facility is a <br />treatment plant, it will be difficult <br />lion, a new facility, or <br />treatment plant appears <br />daily average flow of <br />pre-engineered, package <br />to increase the capacity <br />by modifying existing units. Thus, the more likely means to <br />provide additional capacity to serve the needs of College View <br />MUD and to meet the permitted effluent standards, will be either <br />a new facility or the diversion of flow to the La Porte's main <br />treatment plant. <br />• <br />Turr~rCollie~Braden Inc. <br />
