Custom Manufactured Plastic Tanks

Custom Plastic Tanks

Our structural panels are engineered with hollow core designs and internal stiffening supports, offering a remarkable combination of strength and lightweight properties. The 50mm by 50mm panels, each 50mm thick, are equivalent in strength to half-inch solid sheet material, but they offer enhanced flexibility and are much more structurally efficient. This technology allows us to design custom size water tanks of virtually any shape or size, up to specific capacity and volume requirements, ensuring your tank is custom-made to fit your exact needs, whether you need custom made plastic water tanks, custom marine water tanks, or custom made poly tanks.

Built for Performance and Ease of Maintenance

These custom tanks are equipped with several practical features to ensure reliability and ease of use. Each custom built water tank can include up to four 8-inch flange fitting connections, along with an internal plumbing system for overflow, inlet, and outlet management, making our custom built plastic water tanks ideal for a range of applications. For easy access, the tanks also feature a square bolted hatch on top, allowing users to perform necessary maintenance or cleaning. Inside, they are reinforced with two full cross baffles, ensuring structural stability and making the tank easy to service when required.

One of the key advantages of using Barr Plastics' custom rectangular tanks is their adaptability in difficult installation locations, like the underground spaces of high-rise developments. Traditional poured-in-place concrete tanks are often the only viable option in such scenarios, but our custom-built plastic tanks offer a lighter, more flexible alternative. Whether for stormwater detention, custom storage tanks, or other containment needs, our custom poly water tanks are engineered to deliver reliable performance while being easier to transport and install.

Benefits & Applications

BARR Plastics' Custom Manufactured Plastic Tanks solve critical storage challenges by providing durable, tailored solutions for various applications. Whether in agriculture, where they store fertilizers and pesticides safely, or in chemical processing for hazardous materials, our tanks ensure compliance with safety standards. Additionally, they are highly effective for water treatment systems, emergency water supplies, and industrial requirements. With our precise manufacturing processes, these tanks offer exceptional performance and longevity, significantly improving operational efficiency.

Engineered Potable Water Tanks

Constructed from food-grade HDPE and polypropylene, our tanks are built to meet NSF/ANSI 61 standards for drinking water safety and hygiene. Designed for both indoor and outdoor installations, they offer superior resistance to UV degradation, algae growth, and corrosion-ensuring a clean, long-lasting supply of drinking water under any conditions.

Potable Water Applications

• Residential and cabin drinking water systems
• Off-grid water storage and backup supply tanks
• Agricultural operations and greenhouses
• Commercial kitchens and food processing facilities
• Mining, remote workforce, and temporary camp setups
• Municipal reserve tanks and institutional systems
• Emergency water reserves and preparedness planning

Engineered Grey Water & Sewage Tanks

Effective wastewater containment is essential for maintaining environmental compliance, operational efficiency, and public health—especially in locations where traditional infrastructure is limited or unavailable. Our tanks are fabricated from high-performance, chemical-resistant HDPE and polypropylene, offering exceptional durability, corrosion resistance, and long-term reliability-even in demanding environments.

Applications for Grey Water & Sewage Storage

• Off-grid wastewater systems for cabins, tiny homes, and rural properties
• Commercial greywater systems for laundry, lavatory, or light-industrial reuse
• Mobile waste containment for RVs, boats, marine, or remote work camps
• Temporary or emergency sewage holding tanks at construction sites or events
• Industrial wastewater storage for washdown operations or processing facilities
• Equalization or surge tanks in septic system design and upgrades

Custom Plastic Pump Chambers & Lift Stations Engineered

Ideal for both above-ground and buried installations, our solutions support a wide range of applications including sewage lift stations, stormwater pump tanks, effluent transfer chambers, and remote pump station infrastructure. Tanks can be pre-plumbed and outfitted for rapid deployment, minimizing onsite labor and ensuring code compliance from day one.

From urban infrastructure to remote installations, BARR Plastics delivers custom plastic tank solutions tailored to your operational and environmental needs. Our tanks are more than storage—they’re purpose-built systems that support compliance, performance, and peace of mind.
