CNBC went to the wreckage of the Palisades Fire to ask officials what happened to the water system in LA, and what other cities can do to be better prepared. As many as 1 in 6 Americans now live in areas with significant wildfire risk.
"A firefight at this size, such an urban conflagration, any system is going to have its challenges in maintaining water pressure," said State Fire Marshall Daniel Berlant, of the California Department of Forestry and Fire Protection, known as Cal Fire.
Water pressure was the primary problem, rather than a lack of supply, fire officials and water experts told CNBC.
