Lake Havasu City Council on Sept. 23 approved a materials purchase of TrojanUV 3000-plus ultraviolet disinfection equipment for the Mulberry wastewater treatment plant.

Staff said the current UV disinfection equipment at Mulberry is nearing the end of its service life and that the replacement is part of a three-year capital plan to upgrade UV systems across the city's wastewater facilities. Jason Hart explained the quote is a sole-source purchase because the replacement lamps and specialized modules are proprietary to the Trojan system used at Mulberry. The materials-only quote to Trojan Technologies totaled $705,350; staff said the project's budget is $1,330,000 and installation/labor procurement will follow through a separate competitive process.

Councilmember David Diaz moved approval and the council adopted the purchase 7-0. Hart said the materials are expected to ship in 14'16 weeks after submittal approval and that staff will solicit bids for the installation portion of the work.

Staff described the current equipment as decades-old and said the replacement ensures continued disinfection compliance and will be staged as part of a three-year plant upgrade program.
