Field Erected Corrugated Galvanized Steel
Tanks With "NSF" Approved Coating
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.
Safety
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
10 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.
NSF
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.
Installation
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.
Service
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.

CORRUGATED
GALVANIZED STEEL TANK
TEN YEAR WARRANTY
All corrugated steel water storage tanks are designed to provide
many years of service when properly installed and maintained. Please
review and follow the installation and maintenance guidelines prior to filling tank with water.
Installation
1. Tank
should be located on firm, compacted native soil.
2. Tank should be carefully set on a level foundation of
3/4" crushed rock, 4-6" deep with a minimum 1 foot radius from
tank wall. When seismic design considerations require
anchoring to a
concrete wall or slab, a layer of 1/2" asphalt impregnated fiberboard,
between tank bottom and cement, is necessary.
3. Use dialectic couplings on all metal piping connections to
tank to prevent possible electrolysis.
4. When attaching electric controls or wires to your tank--care
should be taken to prevent cables and control mounting brackets from
contacting tank. Use insulated brackets and other nonconductive materials. Do not use metal anode probes for level control.
Maintenance
1. Water should be changed with fresh water about every three to six months. It is preferable that water be circulated as often as possible. Use water for irrigation, cleaning or other uses, then replenish tank supply with fresh water.
2. If your tank is equipped with an automatic fill shut-off float valve, periodically check the adjustment of the float arm attached to the float ball to prevent over flow.
3. If the water supply contains "hard" or corrosive
minerals, tank interior may require periodic cleaning and recoating. Inspect tank interior and exterior coatings annually, clean and re-coat if needed. Consult with your local factory representative for additional recommendations if necessary. Under normal water conditions, tank
coatings should last the life of the thank (typically 25
years).
To Clean Tank- Wash walls with water and use soft bristle brush to remove rust and mineral deposits. Rinse with water and dry. Leave the top of the tank off. To Recoat Tank- Once tank is cleaned and dried, recoat using a large brush. If it`s a warm day it could take as little as 48 hours to dry. Leave the top of the tank off.

RE:
NSF Corrugated Galvanized Steel Water Reservoirs
Corrugated Steel Tanks will provide years of flawless
service. Our corrugated galvanized storage tanks offer tremendous
advantages over the options for water storage.
The options available to store water in large capacities are limited. They
are either welded or bolted steel tanks. Welded tanks are typically
"butt" welded that rely on a single weld bead for structural
integrity. Certifying the structural quality and penetration of the weld
is not economically feasible for this type of tank construction. Bolted
steel tanks rely on rubber gasket joints that may require periodic servicing for
leakage.
Installation
Corrugated field erected tanks are assembled without the need for heavy
equipment or potentially dangerous welding construction. Corrugated tank
components can be trucked in; hand carried or even dropped in by
helicopter. Expert experienced craftsmen who insure the highest possible
construction integrity fabricate the tanks.
Construction
Corrugated steel has nine (9) times the tensile strength of flat steel
and is superior in resistance to compressive loads. Corrugated steel is
especially resistant to the buckling and "mushrooming" that can affect
flat metal tanks during an earthquake. Corrugated tank seams are
overlapped and hand-riveted with solid steel urethane polymer coated rivets
forming a double thickness of steel that further enhances the lateral and
vertical strength of the tank.
Service
Corrugated galvanized steel tanks have been manufactured in California for
over 100 years. With minimal periodic maintenance, corrugated water tanks
can provide decades of trouble free water storage.
Safety
Most of American Tank Company`s Corrugated Tanks meet Seismic Zone 4
requirements and conform to Unified Building Code (UBC) criteria. Set on a
wide contained gravel foundation, the width of the tank provides resistance to
overturning without the need for expensive seismic anchors. If anchoring
is required or requested, American Tank Company will provide a foundation design
and submittal drawings with a California Civil Engineers wet stamp for building
permits upon receipt of purchase order.
Warranty
There is an unprecedented 10 year manufacturer`s warranty against
defects in material or workmanship that cause either leakage or corrosion.
Date: January 21, 1998
American Tank Co., Inc. has been a supplier of water storage tanks
throughout the United States since 1976. Our Corrugated Galvanized Water
Storage Tanks are commonly used for domestic water storage, fire protection and
small private water systems.
ATC Corrugated Galvanized Steel Water Storage Tanks are structurally
designed to A.I.S.C. engineering criteria. Tanks can be engineered to meet
Seismic Zone 4 design criteria of section 12 of AWWA D-103-87. Our tank appurtenances can be specified to conform to the accessories requirements of
NFPA-22 and Health Department Requirements for Small Water Systems. Our tank sealant (Sika-Flex 201) is NSF approved for drinking water storage applications.
ATC Corrugated Galvanized Steel Potable Water Tanks are lined on the
inside with Farbertite coating.
We apply NSF Approved Polyurethane to our galvanized tanks for the
following reasons:
1. Adhesion - NSF Approved Polyurethane forms a water tight,
molecular bond to galvanize without sandblasting. Sandblasting galvanized steel would remove the factory applied zinc coating,
removing a valuable Secondary defense against corrosion.
2. Application - NSF Approved Polyurethane is factory applied to
all submerged surfaces in strict conformance with the coating manufacturer`s recommended procedures. Field touch up can be easily performed without imposing health or environmental risks associated with field applied epoxy coatings.
3. Acceptance - NSF Approved Polyurethane is accepted by
regulatory agencies for use in water systems including schools, hotels, restaurants, campgrounds and water districts.
