Omfang

This standard describes the design, fabrication, installation, inspection, and testing of bolted aboveground thermosetting fiberglass-reinforced plastic (FRP) panel-type tanks for potable water storage. Requirements for the fabrication, handling, construction, and testing of FRP panels, concrete and steel foundation structure, foundation, and accessories are included. Site elevation and procurement, tank sizing; post-commissioning inspection and maintenance; and the design, operation, and control of the water distribution system that connects to the bolted aboveground FRP panel-type tank are beyond the scope of this standard. Tank roofs. Tanks storing domestic or potable water shall have roofs conforming to the requirements of this standard. Tanks storing nonpotable water may be constructed without roofs. Items not covered. This standard does not cover all details of design and construction. Details that are not addressed shall be designed and constructed to be as adequate and as safe as those that would otherwise be provided under this standard. Local requirements. This standard is not intended to cover storage tanks erected in areas subject to regulations more stringent than the requirements contained within this standard. In such cases, this standard should be followed where it does not conflict with more stringent requirements. Where more stringent federal, state, provincial and local government requirements exist, such requirements shall be specified, and this standard shall be interpreted to supplement them. Purpose The purpose of this standard is to provide minimum requirements for the design, manufacture, installation, and inspection of bolted, aboveground thermoset fiberglass-reinforced plastic (FRP) panel-type tanks for the storage of water. This standard is only applicable to tanks with a base elevation substantially at ground level.
