FTC Tanks can be custom-built with multiple compartments to suit a variety of applications within a single tank footprint. Each compartment is fully isolated, allowing you to store fire water, domestic water, irrigation water, or HVAC makeup—in any combination. Whether you need fire/fire, domestic/domestic, or fire/domestic configurations, we can design the tank to your exact needs. There is no practical limit to the number of compartments, and each is engineered to meet performance and code requirements for its intended use.
