New $6.7M Nanobubbler Systems To Boost Oxygen In Lake Elsinore

Since 2023, the city has deployed multiple technologies to improve the health of the lake, which is the largest natural freshwater lake in Southern California. In addition to the Nanobubbler technology, the city has used algaecide, and Phoslock treatments to clean up the water.

The first Nanobubbler was installed in February 2024 as a pilot project, pumping 500 pounds of oxygen into the lake per day. In October 2024, for phase two, two Nanobubbler systems were installed, each pumping 2,500 pounds of oxygen per day. With the city council’s approval on July 28, phase 3 will upgrade the pilot Nanobubbler and barge, and add a second unit, both equipped with ozone technology, which are expected to each pump 5,000 pounds of oxygen per day.
