FIRE PROTECTIONBENEFITS

NFPA 22 COMPLIANCE

DN Tanks designs and constructs fire protection tanks in accordance with the National Fire Protection Association Standard 22 (NFPA 22) and the AWWA D110 Standard.

SINGLE PARTY RESPONSIBILITY

All aspects of tank design and construction, including tank insulation and heating systems, are performed by DN Tanks providing a turn-key solution for your fire protection storage needs.

NO OUT OF SERVICE TIME

The concrete interior of an AWWA D110 tank eliminates the need for protective coatings and the downtime associated with periodic coating maintenance. By eliminating down time for maintenance, a prestressed concrete tank ensures your facility is continuously protected with reliable fire suppression storage.

FLEXIBILITY

DN Tanks provides the ultimate flexibility in siting and architectural enhancements to fit your project. Our tanks can be constructed at-grade, partially buried, or fully buried. Architectural elements including painted logos, brick veneers, EIFS systems, or other aesthetic enhancements can be included to compliment nearby buildings and structures.

UNPARALLELED DURABILITY & RELIABILITY

Our unique design features provide unmatched durability and service.

PRECAST WALL CONSTRUCTION

The tank walls are horizontally precast in one continuous concrete pour with no horizontal joints. Each panel is inspected and tested before it is incorporated into the structure. This provides the highest degree of quality control by casting on-site individual sections.

EMBEDDED STEEL DIAPHRAGMA continuous steel diaphragm acting as a water barrier is permanently encased in concrete in the finished tank wall. This provides assurance for long-term reliability and elimination of leakage.

FLEXIBLE FLOOR WALL CONNECTIONS

The tank is constructed so that the floor and walls are structurally independent. This allows the wall to expand and contract without placing excessive bending stressed on the wall or floor.

EXTERNAL WIRE-WOUND PRESTRESSING

The tank walls are placed into compression by circumferential prestressing. Every prestress wire is fully encased in shotcrete to provide long term corrosion protection. This ensures the tank walls will remain in permanent compression, eliminating shrinkage cracks, stress cracks, seepage, and deterioration.

SPEED OF CONSTRUCTION

DN Tanks’ on-site precasting operation permits simultaneous construction of the tank walls and floor; resulting in a fast and efficient tank construction process. With no need for protective coatings, the construction time can be further reduced by placing the tank into service immediately upon structural completion.

LOCAL INVESTMENT

DN Tanks’ on-site construction process provides a boost to the local economy by incorporating local materials, labor, and equipment into every project we construct.
