Kudos to this city chief for having the foresight to supplement the city water system for a fire in an industrial building. Not only does this improve efficiency and supplies much needed water - but it reduces city water usage.
The city ladder truck’s water supply was from a city hydrant.
Three portable tanks supplied by tankers were used for a mutual aid pumper’s water supply. The tankers drafted water from a nearby river.
Additionally, two vacuum tankers were drafting from a river and alternately dumping into a portable tank to supply a mutual aid engine. They were able to supply 900 gpm of water from this site.
