Posted: 1:51 PM- PROVO - Provo will spend $200,000 to add high-tech equipment to fight cryptosporidium at swimming pools.
    Utah had more than 1,900 cases of crypto last year. It can spread in water contaminated with human feces and cause diarrhea and other problems.
    The ultraviolet disinfectant systems will be installed at the Veterans Memorial Pool and Waterslide Park complex and at the Provo Recreation Center.
    The equipment works by shining rays on water as it circulates through the system. It can take 24 hours to clean a pool, and there still can be some water that doesn't pass through the system.
    Salt Lake County is trying a similar strategy.
