  • Treating the swimming pool water at The Centre with ultraviolet light won’t eliminate the need for chlorine treatments, but it likely will cut down the amount of chlorine needed, according to a report to the Rolla City Council.
    “With the introduction of UV, a reduction in chlorine levels will provide for greater longevity in the facility and equipment,” Parks and Recreation Direction Scott Caron wrote in his agenda commentary for tonight’s council meeting.
    Caron said the PoolPak is scheduled to be replaced May 28-June 2, and the pool will be closed at that time.
    During the design phase for the replacement, the company doing the work suggested the addition of the UV disinfection process.
    “The patron experience is improved due to a reduction in the chemicals and the facility is protected with the reduction in metal-corroding chloramines,” Caron said. “The greatest benefit of UV treatment is short-wave ultraviolet light has a photo-oxidation effect that destroys chloramines and other toxic byproducts of chlorine. This is done without adding any further chemicals to the water.
    “Less chlorine is used to provide bacterial control, resulting in improved water quality and atmospheric conditions (lower chlorine smell). The primary UV disinfection process destroys all bacteria. In particular, this protects bathers against bacteria in the filter re-entering the pool,” Caron’s report states.
    Caron acknowledged this will reduce, but not eliminate the need for chlorination. Nevertheless, he said, “current chemical costs for the indoor pool averaged $11,500 over the past five years. Some facilities have reduced the chemical consumption by 75 percent, but usually around 50 percent. The use of UV will increase electrical costs minimally, though.”
    The company doing the work is preparing the final costs, expected to be about $55,000.
    Caron said the annual operating savings will be $5,000 to $6,000 per year, along with enhanced air quality.
