Choosing the Right Liquid Storage Tanks for Data Centers: A Practical Guide
In today’s data-driven world, uptime matters. Behind every seamless online transaction, streaming service, or remote login, there’s a data center working around the clock. And while servers and networking gear usually steal the spotlight, there’s a behind-the-scenes hero supporting it all—liquid storage tanks.
From backup fuel to water for cooling systems, storage tanks play a huge role in keeping data centers running smoothly. If you’re managing or designing a facility, understanding your storage needs is key to reliable, uninterrupted performance.
Let’s walk through what you need to know—and how to choose the right tank for every task.
What Exactly Is a Data Center?
Think of a data center as the digital brain of a company or service. It houses critical IT hardware: servers, networking equipment, and massive storage systems. These facilities support everything from cloud storage and financial transactions to health systems and streaming platforms.
They come in all shapes and sizes—modular, cloud-based, colocation, hyperscale, edge—you name it. But they all rely on efficient infrastructure. And that includes more than just fiber optics and firewalls.
Why Storage Tanks Matter in Data Centers
Sure, data centers handle digital storage. But they also depend on liquid storage to keep operations stable, safe, and sustainable.
Here’s how tanks help:
- Power backup fuel storage
- Water for cooling systems
- Fire suppression support
- Rainwater harvesting to cut costs and conserve water
- Chemical handling for equipment maintenance
- Emergency potable water and wastewater management
Bottom line? A smart tank setup helps reduce downtime, improve energy efficiency, and keep systems compliant with regulations like NFPA, EPA, and ASHRAE.
Key Storage Tank Applications in Data Centers
Let’s break down the common uses for storage tanks in these facilities:
Glycol Tanks for Cooling Systems
Servers generate an enormous amount of heat. A large data center can push out 20 to 50 megawatts, and some campus-scale facilities exceed 300 MW—enough to power a city.
To keep things cool, many centers use glycol-based cooling systems. Glycol lowers the freezing point of water and keeps temperatures stable across the system.
Why Tanks Matter
Glycol is toxic and needs to be stored safely. Having a dedicated glycol tank ensures proper containment, minimizes risks, and helps maintain optimal cooling performance.
Fuel Storage for Backup Generators
Data centers can’t afford to go dark—even for a second. That’s where backup generators come in, powered by stored diesel fuel.
Most facilities store enough fuel to run their generators for 48 to 72 hours. Tanks must be compliant with safety standards and sized appropriately for your power needs.
Pro Tip:
HDPE liquid storage tanks with a specific gravity of 1.5+ are a popular choice for DEF storage thanks to their durability, chemical resistance, and regulation compliance.
Aluminum fuel tanks are becoming a go-to choice for commercial operations requiring frequent fueling. Lastly, stackable lubes offer a dependable option for storing oils, lubricants, antifreeze, and more.
Rainwater Harvesting Tanks
Did you know the average data center can use 300,000 gallons of water per day—equal to the usage of about 1,000 homes?
To reduce strain on local water systems (and utility bills), many data centers collect rainwater. This water can be reused for:
- Cooling towers
- Landscape irrigation
- Non-potable flushing systems
A properly sized rainwater harvesting tank is a smart investment for data centers aiming to meet sustainability goals.
Water Storage for Cooling & Fire Suppression
Water tanks do double duty in a data center:
- Cooling Support: Above-ground water tanks feed cooling towers, helping to maintain stable temperatures.
- Fire Safety: Data centers need quick access to large volumes of water in case of emergency. That’s where NFPA-compliant fire suppression tanks come in.
Need a Large Tank?
Plastic Mart offers bulk storage options made from steel, poly, and fiberglass for industrial-scale applications.
Other Helpful Tanks for Data Center Operations
Your facility might also benefit from these specialized storage solutions:
DEF Tanks (Diesel Exhaust Fluid)
For generators with emission control systems.
Chemical Storage Tanks
Safe containment for biocides, pH adjusters, and corrosion inhibitors used in cooling towers.
Portable Water Tanks
Emergency or onsite drinking water supply, especially for remote data centers.
Wastewater Holding Tanks
For capturing and treating graywater or condensate before disposal or reuse.
Oil Storage Tanks
Store used oil for biofuel production, motorized equipment use, or as a lubricant.
Each of these plays a role in improving efficiency, safety, and environmental compliance.
Choosing the Right Tank for Your Data Center
Here’s what to keep in mind before hitting “Add to Cart”:
Capacity Planning
Estimate how much fuel, glycol, or water you need based on daily operations, emergency reserves, and growth expectations. Bigger isn’t always better—pick a size that aligns with your usage and space.
Material Selection
We recommend polyethylene, fiberglass, or stainless steel depending on the liquid type and environment. Poly tanks are versatile and cost-effective, while steel is ideal for fire safety.
Safety & Compliance
Stick with tanks that meet NFPA, EPA, and ASHRAE standards. This keeps your site safe and avoids regulatory headaches.
Space & Installation
Got limited space? Consider vertical tanks for a smaller footprint or underground tanks to save surface area. We also offer installation accessories to help you set it all up the right way.
Maintenance & Monitoring
Choose storage tanks that are easy to clean and inspect. Some liquids, like glycol or diesel, require more frequent checks for leaks or contamination. Consider adding level sensors or digital monitors for peace of mind.
