Officials from Lake Elsinore and representatives from a water treatment company that deployed a system earlier this year to eliminate algae and other impurities in the 3,300-acre water body will hold a “Global Water Summit” a week from Tuesday to highlight progress in the transformation process. The city’s partnership with Hawthorne-based Moleaer Inc. was announced just before Christmas, and within a couple of months, the company deployed its Nanobubble Generators system to begin cleansing the water, in what Lake Elsinore Mayor Steve Manos characterized at the time as a major move toward “progressive and sustainable change.”
