Non-pressurized, atmospheric water-storage tanks
BreakTank non-pressurized, atmospheric water-storage tanks are designed for secure water storage in domestic water and fire protection systems. Commonly used where water resources, supply, or pressure are limited, these tanks rely on gravity for flow and can be installed upstream of domestic or fire pumps to provide spare storage and backflow protection.
The three main types of BreakTanks include welded-steel, corrugated steel, and precast concrete. Welded tanks are above-ground units structurally engineered and built to ASTM A36 standards in sizes from 100 to 40,000 gallons. Corrugated tanks use corrugated galvanized steel to create a lightweight storage solution that ships easily for onsite assembly with sizes from 800 to 440,000 gallons. Precast concrete storage tanks are structurally engineered for strength and durability in direct-bury applications. They’re manufactured in sizes from 500 to 50,000 gallons with optional interior linings available. Underground tanks are a space-saving solution that provides additional security and protection from the elements.
BreakTank tanks are resistant to wind, snow and seismic activity. NFPA 22-compliant tanks support buildings with a substantial risk of fire, such as industrial facilities and high-rise buildings. Typical applications include potable water storage, fire protection water storage, building or green roof irrigation, wastewater storage, and rainwater harvesting.
Each BreakTank is designed as a complete system with key components and accessories included. Tanks are equipped with high- and low-water sensor and alarm systems that monitor and control tank levels. Mechanical float-operated or electronic solenoid-actuated fill valves control water inflows when connected to a potable water pressure source. A control panel with alarms alerts operators when levels are too high or too low, while a sight gauge allows easy visual inspection of water levels. These tanks include an overflow pipe that allows excess water to escape into a floor drain if water levels rise too high, and drain ports in the bottom for maintenance and cleaning.
For safe access and long-term durability, BreakTank systems also incorporate top and side manways, interior and exterior ladders and accessories, such as access hatches, overflow drains, and automatic control systems. Interior liners, available in HDPE, PVC or epoxy, are applied to protect tank interiors from corrosion or contamination, while long-lasting exterior liners are standard for corrosion protection. Stilling wells and anti-vortex plates help stabilize water conditions inside tanks, and support efficient pump operation.
