Fire Water Tanks

Above Ground, Corrugated Steel 
​by Corgal 

Corgal leads the field in the design and engineering of fire protection tanks for water storage. We produce dedicated reservoirs and water supply configurations and each tank is individually engineered for its application, whether commercial, industrial, or municipal. Corrugated Steel Above-Ground Tanks are often the most economical and longest lasting form of storage for fire protection water. Corgal offer a huge range of approved tanks that conform to NFPA-22 requirements. The modular bolted design allows for a fast and easy installation in all types of weather and requires no field coating, welding, or cranes. The polymer liner design is less expensive intially, requires less routine maintenance, and is easier, faster, and less expensive to refurbish than spray coatings. All CorGal water storage tanks are engineered to these minimum standards: ○ 100% Class 1 Structural AMERICAN MADE STEEL ○ G-115 hot dipped galvanization ○ 20-gauge steel sidewalls ○ 24-gauge steel roof panelsDesignated bottom wall sheets to better distribute weightFull tank geotextile preliner24 mil PVC flexible membrane linerSchedule 80 PVC flanges or hot-dipped galvanized steel flanges TANKS ENGINEERED SITE SPECIFIC We offer a thorough, site specific structural design calculation package (SDCP), stamped by a professional engineer licensed in the project location state. This ensures each tank is built to the location’s specific requirements and complies with local ordinances and laws, protecting all parties. Site specific tanks may incorporate thicker metal wall sheets or roof panels, stiffeners, heavy duty anchors, and other components to satisfy the local seismic, wind speed and live load requirements. We take engineering very seriously for the safety and security of all parties involved.

Corgal is superior in quality, and Georgia Water Tanks provides the best service in the Georgia. Our exclusive 30-year warranty on structural components is the strongest of any company like it. Georgia Water Tanks adds on to the parts-only warranty, so the WARRANTY INCLUDES LABOR

Underground, Fiberglass

by Containment Solutions

​​Watertight Flowtite® tanks, from Containment Solutions, can be custom built for any fire protection design. We understand the requirements of fire protection systems, and manufacture our tanks to National Fire Protection Association (NFPA) standards.

By providing a dedicated source of water required by local codes in residential development, CSI fiberglass tanks are a preferred way to have access to large volumes of water. The tank provides unseen protection for the residents, yet is easily accessible for fire and municipal vehicles. Flowtite tanks are also used for commercial fire protection due to the inherent water tight properties of fiberglass and the large volume capacities.
