La Verne lifts evacuations after battery fire at MWD's Weymouth plant
The City of La Verne said on September 25, 2026 that all evacuation orders from the September 22 lithium battery explosion and fire at the Metropolitan Water District's Weymouth Water Treatment Plant had been lifted after crews removed the modules overnight. The city says two 250-kilowatt units serving a solar farm were involved, one burned and the second overheated; its September 25 summaries put air monitoring in the normal range; the packs are expected off site within 3 to 5 days of September 25, pending materials; MWD then leads the investigation; the City Council meets September 29.
