How to Spec a Fire Protection Tank
Speccing a fire protection tank is less about a single number and more about a handful of decisions that have to line up: the construction type, the material and coating, the fittings, and the standards behind them. This page walks through those decisions in the order an engineer usually meets them, so the fire protection water tank specs you land on hold up to review.
It stays at the level of how to weigh each factor rather than fixed figures, since those change from tank to tank. Once you know which factors drive the choice, sizing the reserve and confirming the numbers with your Authority Having Jurisdiction fall into place.

Overview
What NFPA 22 Covers
NFPA 22 is the standard that governs water tanks supplying private fire protection systems. At a high level, it addresses the categories of tank construction that are acceptable, how stored water is kept available and protected, and the fittings and accessories a fire protection tank is expected to carry. The intent is a dependable supply that is sized, built, and maintained for its protective duty. Those requirements sit behind every tank in our fire protection water tanks range.
In practice, a specifier works with three ideas. First, the tank must hold a defined volume of water that remains usable for fire protection. Second, construction and coatings must suit the water, the site, and the service life expected. Third, the tank must include the connections, level indication, and protective features that let the system draw water reliably when it is called for.
Sizing the reserve volume is its own exercise. The figures that determine an actual tank are set by the system designer and the local authority, not by this page. For how those inputs come together, see our NFPA 22 sizing reference. The sections below describe the spec factors that shape selection so a specification conversation can start from the right place.
Fire Protection Water Tank Specs That Drive Selection
| Specification Factor | What It Governs | Where The Figure Comes From |
|---|---|---|
| Tank Construction Type | The acceptable build category for the application and water service | Catalog model, against NFPA 22 acceptability |
| Material And Coating | Corrosion protection and suitability for the stored water and the site | Product spec sheet, matched to water service |
| Usable Capacity | The volume that stays available for fire protection duty | System designer and your AHJ |
| Fittings And Connections | How the system draws, fills, and vents water | Product spec sheet and system design |
| Level Indication | Confirming the reserve is available when it is called for | Product spec sheet |
| Protective Features | Keeping the stored water usable and protected on site | Product spec sheet and NFPA 22 requirements |

Applying The Specs To Product Selection
Once the factors above are settled, matching them to a tank is straightforward. Browse the fire protection tanks category, compare configurations against your specification, and request the spec sheet for any model to confirm its materials, coatings, fittings, and capacity. Pricing and current availability live on each product, so they are not listed here.

Certification And Documentation
Fire protection projects are documented projects. The reference frameworks that may apply to a water tank supply include:
- NSF standards for potable water contact, where applicable
- AWWA references for steel water storage construction
- NFPA 22 for the private fire protection application
We provide the documentation a specifier needs to support submittal and review. Which certifications and reports apply depends on the tank type, coating, and intended water service for your project.
To receive the documentation set for a specific configuration, request a spec sheet and a Sales Specialist will confirm what applies.

FAQ
Fire Protection Tank Specification FAQs
What Standards Apply To Fire Water Tanks?
NFPA 22 is the core standard for water tanks serving private fire protection. Depending on the tank's material and whether the water is potable, references such as NSF for potable contact and AWWA for steel construction may also apply. Which of these apply to your tank depends on its configuration and your Authority Having Jurisdiction.
What Is NFPA 22?
NFPA 22 is the standard for water tanks that supply private fire protection systems. It sets out the acceptable categories of tank construction, how the stored water is kept available and protected, and the fittings and accessories a fire protection tank is expected to carry. It governs the tank as a water source, while the system design and your Authority Having Jurisdiction determine the figures for a specific project.
How Big Does A Fire Protection Water Tank Need To Be?
Tank size comes from the flow rate and duration your fire protection system has to sustain, which the system designer and your Authority Having Jurisdiction set for the project rather than from a fixed rule of thumb. Because that calculation stands on its own, we keep it separate. See our NFPA 22 sizing reference for how the inputs come together.
What Are Fire Protection Water Tanks Made Of?
Construction type is one of the core spec decisions. Fire protection tanks are often built in steel, with other construction types available depending on the water service, the site, and the expected service life. NFPA 22 addresses which construction categories are acceptable for the application, and the options that apply to your project are shown on the product pages.
What Coatings Are Used On Fire Tanks?
Coating selection follows the tank material, the water service, and the site environment rather than a single default. The right interior lining and exterior coating for a given tank are listed on its spec sheet. Request the spec sheet for any model to confirm the coating that applies to it.
What Fittings Are Required?
A fire protection tank carries the connections that let the system draw, fill, and vent water, along with level indication and protective features. The specific fittings required for your installation are set by the system design and your AHJ, and the fittings supplied with each tank are listed on its spec sheet.
Can A Fire Protection Tank Store Potable Water?
Some configurations can, when the tank's materials and linings meet the standards for potable water contact, such as the NSF references noted above. Whether a given tank is suitable for potable service depends on its construction and coating and on your Authority Having Jurisdiction. Request the spec sheet for any model to confirm what its water service supports.
How Much Does A Fire Protection Water Tank Cost?
Price depends on the capacity, construction type, coating, and fittings a tank carries, so there is no single figure. Current pricing is shown live on each product, and for a configured build a Sales Specialist can return a quote. Send us your specification through the request form and we will price what applies.
