Description
Cleveland Utilities Authority (CU) owns and operates the Waterville Springs Water Treatment Plant (WTP), located south of Cleveland, Tennessee off Southeast Dalton Pike adjacent to the Falcon Pointe Golf Club. The WTP obtains groundwater from springs and injects chlorine solution for disinfection before sending to their distribution system. The WTP uses chlorine gas cylinders (150-pound) to produce chlorine solution for disinfection with a maximum of two (2) in service at a time. CU selected Stantec Consulting Services Inc. to design a fixed media scrubber and appurtenances to protect their employees and the public from potential chlorine gas leaks. The project installed fixed media chlorine gas scrubber equipment with sensors, ventilation fan and ductwork to address accidental chlorine gas releases in the building. The system was designed in accordance with CU safety guidelines, the National Fire Protection Agency (NFPA), the Uniform Fire Code (Article 80) regulations and the Tennessee Department of Environment and Conservation (TDEC) Community Public Water Systems Design Criteria. The scrubber system included a blower to ventilate the room at 900 cfm to meet the TDEC criteria for one complete air change per minute. The scrubber equipment includes FRP reactor tank with media to reduce chlorine gas releases from two 150-pound cylinders to below 5 ppm. The existing building is located very close to a fairway at the Falcon Pointe Golf Course and has experienced damage to windows and other equipment by errant golf shots. CU staff report that they have to be cautious about potential golf ball damage to vehicles and even themselves. Every weekend golfer knows we rarely hit the ball exactly where we aim! Because the WTP and scrubber equipment are “in the line of fire” for errant golf shots, we added higher fencing with protective netting over the scrubber equipment and protective covers over the new FRP ductwork. Therefore, this project accomplished somewhat unique dual goals: •Protect employees and the public from chlorine gas leaks •Protect the equipment from damage by errant golf balls This presentation will cover the regulatory criteria, scrubber equipment design and installation, golf ball protection enhancements, and construction photographs. The additional golf ball protection (higher fencing and netting) only added $7,950 to the total project costs, well worth the cost to protect the equipment from golf ball damage. The project was completed and placed into service in August 2024 with a total construction cost of $353,200.
