Above Ground Potable Water Storage
NTP FRP Water Tanks are built to AWWA Standards using NSF approved resins with UV inhibitors to ensure durability.
In addition to National Standards, NTP adheres to the following Standards:
- ASTM D3299: Standard Specification for Filament-Wound Glass-FiberReinforced Thermostat Resin Corrosion-Resistant Tanks
- ASTM D4097: Standard Specification for Contact-Molded Glass-FiberReinforced Thermoset Resin
- ASTM C-581: Standard Practice for Determining Chemical Resistance of Thermosetting Resins used in Glass Fiber Reinforced Structures Intended for Liquid Service”
- ASTM D-883: “Definition of Terms Relating to Plastics”
- ASTM D-2563: “Recommended Practice for Classifying Visual Defects in Glass Reinforced Plastic Laminate Parts “
- ASTM D-2583: “Test for Indentation Hardness of Rigid Plastics by Means of Barcol Impressor”
- ASTM C582 Table 5: Classifying Visual Defects in Glass Reinforced Laminates and parts there from.

The Benefits of Fiberglass
- Fiberglass tanks have a long history of use in applications where watertight design integrity is critical, including extensive use in the storage of motor fuels. Leak-free performance is essential when it comes to fire protection water storage.
- Installation steps and costs are minimized by the lightweight nature of fiberglass since expensive heavy-lifting equipment generally is not necessary. This also is an important consideration when tank installation sites are difficult to access.
- Large capacity tanks, up to 60,000 gal. Sizes generally required in fire protection systems, are factory-manufactured products that provide superior quality control processes vs. fabricating a tank on site where it is subject to varying weather conditions and manufacturing controls.
- A fiberglass tank can be designed for dual-purpose use, with a common example being fire protection standby as well as potable water. A fiberglass tank can be ordered with a National Sanitation Foundation listing for potable applications.
