Custom Polyethylene Tank (HDPE)

Custom HDPE Tanks

You need a tank that fits your space and your process. We build custom HDPE tanks to your exact specs. You get reliable storage, long service life, and strong chemical resistance.

BARR Plastics manufactures tanks for industrial, commercial, and municipal projects across North America.

Why Choose HDPE Tanks

HDPE performs well in tough environments.

• High chemical resistance - handles many acids, bases, and salts
• Corrosion proof - will not rust or rot
• Impact resistant - absorbs shock better than many rigid plastics
• Lightweight - easier transport and installation
• Long service life - often 15 to 25+ years depending on use

HDPE works well from about -40 C to 60 C in many applications.

Fully Custom Built

You choose the dimensions and features. We fabricate tanks to fit tight mechanical rooms, crawl spaces, and unusual layouts.

You can specify:

• Length, width, height, and shape
• Wall thickness based on load and contents
• Flat bottom or sloped bottom
• Internal baffles
• Lids, hatches, and manways
• Lifting lugs and supports

We build tanks too large to move through doors in sections and assemble on site when needed

Fittings and Connections

We install fittings at the factory to match your system.

Common options include:

• Inlet and outlet bulkhead fittings
• Flanged nozzles
• Overflow connections
• Drain fittings
• Level sensor ports
• Vent fittings

You send us a drawing or sketch. We place fittings exactly where you need them.

Typical Applications

You see HDPE tanks in many industries.

• Potable and non-potable water storage
• Wastewater and process water
• Stormwater systems inside buildings
• Chemical storage and batching
• Agricultural liquid storage
• Food processing wash water, where allowed by code

For example, a facility may use a 2,000 gallon HDPE tank for process water reuse. A mechanical room may use a low-profile tank under 48 inches tall to fit under piping.

Fabrication Quality

We use industrial-grade HDPE sheet. Certified plastic welders fabricate each tank.

• Thermoplastic welding creates strong, leak-tight seams
• Reinforcement ribs reduce wall deflection
• Tanks are pressure tested or leak tested as required
• We build to project drawings and engineering requirements

Material and design can be selected to meet NSF, FDA, or other standards when your application requires it.

Size Range

We build small and very large tanks.

• Small tanks under 100 gallons
• Mid-size tanks from 100 to 5,000 gallons
• Large tanks 5,000 gallons and up

Actual size depends on shape, wall thickness, and site access.
