Norwesco Tanks: Complete Manufacturer Guide and Product Review
Norwesco: Manufacturer Overview
Norwesco is the largest rotational molder of polyethylene tanks in North America, operating 15 manufacturing plants across the United States plus 2 in Canada. Founded decades ago, the company has built its reputation on the broadest product line in the industry, consistent quality, and a nationwide manufacturing network that keeps shipping distances and lead times short.
Company History and Background
Norwesco grew from a single rotomolding facility into the industry leader through strategic acquisitions of regional tank manufacturers and continuous expansion of their product line. Today they produce everything from 10-gallon utility tanks to 10,000-gallon bulk storage tanks, plus a comprehensive catalog of fittings, valves, and accessories. Their manufacturing network means most orders ship from a plant within a few hundred miles of the destination, reducing freight cost and transit time.
Product Line
Norwesco manufactures vertical storage tanks, horizontal tanks, cone bottom tanks, doorway/slimline tanks, septic tanks, water storage tanks, loaf tanks, applicator saddle tanks, elliptical tanks, pickup truck tanks, and a full line of polyethylene fittings and accessories. Capacities range from 10 gallons to 10,000+ gallons across multiple configurations.
Manufacturing Quality and Standards
Every Norwesco tank is manufactured from proprietary resin formulations specifically engineered for rotational molding. UV stabilizers, antioxidants, and processing aids are compounded directly into the resin — not applied as surface coatings. This means the protection extends through the full wall thickness, not just the surface. Every tank is visually inspected before it leaves the production floor, and quality control includes wall thickness measurements, fitting torque verification, and dimensional checks against engineering specifications.
Warranty Coverage
Norwesco backs their tanks with a manufacturer warranty against defects in materials and workmanship under normal use conditions. The warranty covers manufacturing defects including cracks, pinholes, material failures, and fitting defects present from the factory. It does not cover damage from exceeding rated specific gravity, improper installation, chemical attack from incompatible substances, UV degradation beyond the rated service life, physical impact damage, or modifications to the tank after purchase.

How to Choose the Right Norwesco Tank
Selecting the right tank from Norwesco's extensive product line starts with answering four questions:
1. What are you storing?
The chemical you plan to store determines the specific gravity rating, material compatibility, and any certifications required. Water storage needs FDA-approved tanks. Agricultural chemicals need SG 1.5+ rated tanks. Each application has specific requirements that narrow your options to the right product category.
2. How much capacity do you need?
Calculate your storage needs based on daily usage, refill frequency, and peak demand. Add a 20% safety margin to account for delivery delays and peak usage periods. It is always better to have slightly more capacity than you need — the cost difference between adjacent sizes is usually small compared to the inconvenience of running out.
3. What are your space constraints?
Measure your installation space including clearances for plumbing, inspection access, and maintenance. Vertical tanks use the least floor space. Horizontal tanks work under low clearances. Doorway tanks fit through standard doors for indoor installation. The right shape depends on your specific site conditions.
4. What is your budget?
Norwesco offers products across a range of price points. Water-only tanks cost less than chemical-rated tanks. Standard configurations cost less than specialty designs. But remember — the tank itself is typically the smallest part of the total installed cost. Foundation, plumbing, delivery, and installation usually exceed the tank price. Saving $100 on the tank while creating a $500 plumbing problem is a bad trade.
Frequently Asked Questions About Norwesco
Where are Norwesco tanks manufactured?
Norwesco operates manufacturing facilities across North America. Tanks are typically shipped from the nearest facility to minimize freight cost and transit time. Contact us for specific lead times and shipping estimates to your location.
Are Norwesco tanks FDA approved for drinking water?
Norwesco offers FDA-approved tanks for potable water storage. Not all tanks in their line carry FDA approval — specifically request FDA-approved tanks if you plan to store drinking water or food-grade liquids. The product listing will indicate FDA approval status.
What is the warranty on Norwesco tanks?
Norwesco provides manufacturer warranties against defects in materials and workmanship under normal use conditions. The warranty requires proper installation according to manufacturer guidelines, use within rated specifications (specific gravity, temperature, chemical compatibility), and normal handling and maintenance. Keep your purchase receipt and installation photos for any warranty claims.
Can I get custom fittings or modifications on a Norwesco tank?
Many Norwesco tanks are available with custom fitting locations, additional outlets, and other modifications. Custom work may require additional lead time and cost. Contact us to discuss your specific requirements — we can coordinate directly with Norwesco for custom orders.
How long do Norwesco tanks last?
Under normal conditions with proper installation and maintenance, Norwesco polyethylene tanks typically deliver 15-20+ years of service. Actual lifespan depends on UV exposure, chemical storage history, temperature cycling, and installation quality. Tanks used within their rated specifications consistently reach or exceed the 15-year mark.
