2. REQUIREMENTS
Based on a regularly scheduled April 2022 inspection report, the City is exploring the option to replace the Overlook Standpipe with a new tank. This will require evaluation, recommendations, engineering, and design to determine the following:
- Correct sizing: Whether to remain at 150,000 gallons, or increase/decrease volume;
- Location: Replace on the existing standpipe footprint, or locate at a different spot on the reservoir site;
- Modeling and State TDEC permit requirements;
- Installation plan to avoid disruption of service to existing customers
- Demolition/Removal plan for existing tank
(a) The current City of Alcoa Water Overlook Standpipe is located on the City’s Reservoir facility at 2909 to 2915 Patrick Avenue, Maryville, TN. The standpipe supports the Overlook Pressure Zone, consisting of approximately 415 customers, some of whose properties are located above the elevation of the City’s main reservoir tanks.
(b) The Overlook Standpipe was constructed in 1980 by Caldwell Tanks, Inc. of Louisville, KY.
- Tank No.: D8762
- Capacity: 150,000 gallons
- Type: Ground steel with stainless steel roof
- Height: 64-feet, 0-inches
- Diameter: 20-feet, 0-inches
(c) The standpipe supported by the Overlook Booster Pump Station No. 1 (2 pumps, 170 gpm each), also located at the City’s reservoir site.
(d) The standpipe was most recently inspected on April 29, 2022 by SE Diving Services, Greenville, SC. The inspection consisted of an external visual inspection, and an internal inspection by divers. Following the inspection, the tank was cleaned. The inspection determined that the overall condition of the standpipe was : POOR.
