Underground Concrete Water Storage Tank
Underground Concrete Water Storage Tank
(OP)
I am designing the piping and equipment for a fire suppression system which includes an underground concrete storage tank. The tank will be located below an expansion of the existing building. Some of the walls of the tank will also serve as the foundation of a part of the building.
The way I read and interpret NFPA 22 is that the tank walls must be poured concrete construction.
The architect wants to use a block wall construction.
I need to know if I should bring this up.
Thanks

Is there going to be access for maintance????
1.2 Purpose.
The purpose of this standard is to provide a basis for the design, construction, operation, and maintenance of water tanks for private fire protection. Nothing in this standard shall prevent the use of systems, methods, or devices that are equivalent in quality, strength, fire resistance, effectiveness, and durability to those prescribed by this standard, provided technical documentation is made available to the authority having jurisdiction that demonstrates equivalency, and the system, method, or device is appropriate for the intended purpose.

There is an access hatch for maintenance.
I agree that there is nothing in the code that explicitly prohibits the use of CMU but my concern is that it would be a whole lot easier sealing a single piece of concrete than it would to seal several joints inherent in the use of CMU. It can be done, but I would be concerned.
