If you like sub sandwiches and would like to help firefighters, police and other first responders stay hydrated during the severely hot summer hitting the Valley, then Firehouse Subs has an offer for you.

On Saturday, anybody who donates a 24-pack of bottled water will receive a free medium sandwich from any of company’s restaurants in 44 U.S. states, Puerto Rico, Mexico, and Canada. 

Firehouse Subs’ only Valley location is at 128 W. Nees Ave. in Fresno, northwest of the Blackstone Avenue intersection.

“With record-setting high temperatures creating dangerous weather conditions across the country, Firehouse Subs invites guests nationwide to help in its effort to support America’s first responders with the sixth annual H2O for Heroes bottled water collection drive,” states a press release from the Jacksonville-based company.

Last year’s drive – which was the second to occur nationally after being started in Arizona – brought in more than 528,000 bottles of water.

And organizers say that with record heat occurring across the country this year and wildfires igniting from California to Georgia, the need for donated water remains high.

“We hear from so many departments that don’t have the additional money to purchase bottled water, and the donations they receive from our guests assist them in a variety of emergency situations,” said Firehouse Subs Franchisee Windy Griffin, who, along with her husband, Jerry, launched the water-collection campaign at their Phoenix-area restaurant in 2012.

“From hydrating firefighters in the scorching summer heat to keeping K9 officers cool on patrol, this water is a life-saving tool,” she said in a written statement.

All the water donated will be distributed to local first responders as well as to local organizations that aid people in need of water, the release continues.
