The El Centro City Council approved an upgrade to the disinfection system at the city’s wastewater treatment plant on Tuesday, Feb. 19, at City Hall. “Ultraviolet light disinfection is the last treatment process to eliminate any remaining bacteria in wastewater before it is released,” Public Works Director and City Engineer Abraham Campos said. The UV-treated water is discharged into the Imperial Irrigation District’s drainage system and ultimately into the Salton Sea, according to city documents.  The existing UV lamps, which have been in use for the past 15 years, will no longer be serviceable as manufacturers and current part suppliers are transitioning to a new system.
