Field Erected Galvanized Steel Tanks w/NSF Coating

Field Erected Corrugated Galvanized Steel Tanks With "NSF" Approved Coatings & Liners

Potable Domestic Water Supply
Private and public water systems, campgrounds and resorts use NSF approved coated tanks for potable water storage applications. NSF coated tanks meet all Federal & State standards for storage of safe drinking water.

Fire Protection Reserve Water Storage
Many county and state fire departments recommend our tanks as economical alternatives to bolted or welded water tanks for fire protection storage.

Most field erected tanks meet seismic safety standards without anchoring, saving the expense of a concrete foundation. Set on a contained gravel foundation, wide diameters provide resistance to overturning without the need for seismic anchors. If anchoring is required or requested, American Tank Co. will provide a foundation design and submittal drawings with a California Civil Engineers wet stamp for building permits or customer approval.

Warranty & Savings Field Erected Corrugated tanks are baked by a one year manufacturer's warranty. Tanks are engineered, hot dipped mill galvanized and corrugated steel. These tanks are extremely cost effective when compared to bolted or welded steel tanks.

Irrigation Water Storage Farms and ranches throughout the west rely ATC tanks to maximize the efficiency of water well production and to control distribution and pumping cycles.

Size Field erected corrugated tanks are typically specified between 20,000 to 150,000 gallon capacities.

Erected on Site Field erected tanks come in sections and are erected on site. This makes the ATC tank an ideal choice for those hard to reach locations.

National Sanitation Foundation is an organization that certifies products that contact potable drinking water. This certification insures that only the absolute safest non toxic materials are used in the interior coating of our tanks. NSF certification meets or exceeds all Federal and State requirements.

Corrugated field erected tanks are assembled without the need for heavy equipment or flammable materials. Corrugated tank components can be trucked in, hand carried or dropped in by helicopter when grading of access roads is not possible or desirable. Please ask your sales representative for details and costs.

Corrugated galvanized steel tanks have been manufactured in California for over 100 years. The normal service life is 25-30 years based on historical observations. With periodic maintenance, ATC tanks can provide 30 to 50 years of qualified service.

Important Customer Notice:
Foundation Requirements For Field Erected
Storage Tanks

When installing your Gravel Ring Foundation, it is mandatory that
ONLY 3/4" Crushed Rock be used.
Do Not Use Pea Gravel.

Failure to use 3/4" Crushed rock in your tanks foundation, will result in time delays and additional labor charges while our erection crew waits onsite for the proper rock to be installed.

Thank you,
