Lake Elsinore council approves $262,685 purchase order with Moliere to address Summerly odor
Summary
After a presentation by Moliere’s CEO, the Lake Elsinore City Council unanimously authorized a purchase order for a 1,000-gallon-per-minute oxygen system to treat anoxic zones and hydrogen-sulfide odors in the Summerly area and portions of Lake Elsinore, authorizing the city manager to execute the agreement for up to $262,685.
Lake Elsinore — The City Council voted unanimously Dec. 10 to authorize the city manager to execute a purchase order with Moliere for up to $262,685 plus applicable sales taxes to install an oxygen-based nanobubble system intended to reduce odors and improve water quality in the Summerly area and other hard-to-oxygenate parts of Lake Elsinore.
The action followed a presentation from Moliere CEO Nick Dine, who described how high‑purity oxygen nanobubbles can be targeted to anoxic zones near the lake bottom where sulfate‑reducing bacteria produce hydrogen sulfide, the compound that causes rotten‑egg odors. "What we're delivering is over 90% oxygen," Dine said, adding that the company has deployed similar systems internationally and in emergency responses in the region.
Mayor Manos summarized the item as an action request and said the city had already tested emergency deployments in November. "The results speak for themselves," he said, praising the speed of the emergency response. The motion to authorize the purchase order was made by Mayor Pro Tem Brian Tisdale and seconded by Councilmember Sheridan; the motion passed with all members present voting in the affirmative.
City staff described the recommended system as a fully integrated, mobile solution sized at 1,000 gallons per minute — smaller than a prior 2,400‑gallon air‑based emergency deployment — but capable of using higher‑purity oxygen for more effective treatment. The council heard that the city had previously used peroxide and air-based temporary systems while crews evaluated longer-term options.
Council members thanked the vendor and staff for a rapid response to recent odor complaints and for pursuing a deployable solution that could be moved to other parts of Lake Elsinore if needed. The council did not discuss contract amendments or long-term maintenance details on the floor; procurement and execution were delegated to the city manager under the approved purchase order.
The item was recorded as an affirmative, unanimous vote; staff will return with contract execution documentation if required by the city’s purchasing rules.
