Types of Water Tenders: Support and Tactical

What is a Water Tender?

A wildland water tender is a specialized vehicle capable of bringing water, foam, or dry chemicals to fire trucks in the field. Water tenders have a large truck-mounted tank with a minimum of 1,000 gallons and up to 4,000 gallons of water. 

Water tenders are typically larger, less agile apparatus. These vehicles are specifically designed for fires in more rugged terrain to help supply water for the fireline. Many modern water tenders can be used tactically to supply critical incident hose lies directly. 

Tenders are typically used in wildfires because urban fire departments usually get their water from water supply infrastructures. In contrast, rural departments transport large volumes of water to the fireline with water tenders because of a lack of access to municipal water systems.

Tactical water tenders can perform some of the functions of a wildland fire engine, such as deploying hose lengths. Unlike support water tenders, tactical water tenders are capable of a technique of pump-and-roll.
