Aquastore
Aquastore glass-fused-to-steel tanks are found in virtually every segment of the liquid storage market. Common applications include storing potable water, wastewater, process water, fire suppression water, and landfill leachate.
Our engineers provide Aquastore tank designs to a wide range of standards, such as AWWA D103 Standard for Bolted Steel Water Storage Tanks, AISC, Factory Mutual codes and National Fire Protection Association Standard 22. Submittal drawings and design calculations are available for every tank.
Aquastore sectional bolted tanks offer several advantages that have contributed to their success. They are cost-effective. Compare the life-cycle cost of a glass-fused-to-steel tank to a field-welded or concrete tank and the difference is significant. Glass coatings do not require periodic repainting and most graffiti can be removed in a matter of minutes.
Factory coating eliminates the weather delays and variables affecting the quality of field-applied paint. The unique design and bolt assembly of the tank can be pre-engineered to allow for capacity expansion in the future. Gateway Tank utilizes a variety of sealants with specific chemical resistant properties suited to the liquids to be stored. Aquastore tanks can be erected in remote locations and can be designed for relocation. Best of all, their performance is dependable, with minimal maintenance cost.
Interior and Exterior Coating
The heart of the coating system is a multi-step glass-fused-to-steel process. The fabricated sheets are grit blasted to a uniform, near white surface. The sheets are then inspected and pre-coated. Proprietary formulations of borosilicate, minerals, water and clays are blended into a sprayable slurry. After inspection, the slurry is fused to the steel sheets at temperatures above 1500 degrees Fahrenheit to produce the distinctive glossy Aquastore finish. The molten glass reacts to the profiled steel surface to form an inert, inorganic chemical and mechanical bond.
Gateway Tank uses Engineered Storage Products’ proprietary Edgecoat process, which thermal sprays the edges with a protective alloy. Glass is added to double coat the sheet edges with barrier coatings. For some individualm circumstances, multiple applications and firings produce specialized coatings.
Standard Features
Despite the complexities of manufacturing and glass coatings, Aquastore tanks are relatively simple to specify. Most projects will define the capacity requirement in the earliest stage. The application and any space limitations will determine the configuration. Once these parameters have been determined, there are only a few decision left. Gateway Tank can help you determine the requirements for your application.
The standard features of an Aquastore tank are very basic:
- Glass-fused to steel sidewall panels
- A sidewall manway and the hardware
- Sealant required to assemble the tank
Optional features of an Aquastore tank include:
- Floors and roofs or domes are optional
- Aluminum ladders with cages
- Ladder door assemblies
- Level indicators
- Manway or observation platforms
- Roof walkways and guard rails
- Bottom round access doors
- The Aquastore cathodic protection system
Aquastore’s cathodic protection system consists of sacrificial anodes that mitigate corrosion and provide protection to internal submerged surfaces of the tank. The system is simple, robust and requires only minimum inspection and maintenance. Aquastore tanks are erected from the top down using specialized jacking system. This building method is quick, efficient, safe, and allows the tanks to be expanded vertically in the future.
Aluminum Geodesic Domes
Aquastore Aluminum Geodesic Domes help protect your storage tank. The Aquastore Aluminum Geodesic Dome is available in diameters from 11 feet to 120 feet, provides protection for potable water, wastewater storage and treatment, process water for industry, landfill leachate storage and treatment, fire suppression water and more.
Low-Maintenance Protection
Designed for installation primarily on Aquastore and Tecstore tanks and suitable for retrofitting on any tank, the dome protects drinking water safety and ensures resistance to corrosive vapors for wastewater, process water and landfill leachate applications. Designed for fast on-site installation, the dome is constructed from standard components that allow easy assembly. Its low-maintenance service life also provides cost-efficiencies. The combination of the Aquastore Dome and the Aquastore Tank assures the owner of a low-maintenance service life, with no corrosion or re-painting necessary.
