Steel water tanks

In recent years, we’ve witnessed an increase in extreme weather patterns—longer periods of drought followed by intense, short bursts of rainfall. Coupled with population growth, this has led to a growing scarcity of safe, fresh water. As a result, storing and reusing water has become more critical than ever.

The key to building a reliable water buffer is having a system that can effectively store water. By installing water tanks or basins, you can secure water for future use. Our galvanized steel water tanks provide a dependable solution for your water storage needs, offering a range of benefits for long-term sustainability.

Looking for a dependable water storage solution? Our steel water tanks are engineered for both durability and convenience. Crafted from high-quality steel and premium lining materials, they require minimal maintenance and boast a long lifespan. The closed, impermeable design significantly reduces water loss through evaporation and allows for precise control of water levels. This enclosed system also simplifies water quality management with the integration of filtration or treatment systems.

Despite their robust construction, our tanks are incredibly versatile. Available in a range of sizes, they can store up to 2,500 cubic meters of water while occupying minimal space. Installation is quick and easy—thanks to the prefabricated sections, which include metal panels, liners, protective layers, and optional covers. Simply assemble the sections on-site for a hassle-free setup.

We’ve made global transportation efficient, too. By packaging the tanks compactly, we can ship them anywhere in the world. Designed to fit in tight spaces like trucks and containers, our modular tanks can be delivered even to locations with limited access.

Clean water is essential across many industries, and our steel water tanks provide versatile solutions for a wide range of applications. At NPI, we offer water storage systems tailored to meet the needs of various sectors, including irrigation, fish farming, agriculture, industrial use, civil engineering, firefighting, rainwater collection, and safe drinking water storage. 

At NPI, we provide a diverse range of tanks in various diameters and heights, offering over 400 standard sizes. Whether your needs are for agriculture, horticulture, aquaculture, fire protection, or wastewater management, we have a water tank to fit every type of facility.

We offer fully customizable water tanks, allowing customers to choose the size, materials, and appearance that best suit their needs. Our tanks can be tailored to fit specific requirements, surroundings, and personal preferences. Whether it’s size, material, or design, we adjust every detail to meet your exact specifications.

We manufacture our modular tanks as prefabricated kits, ready for easy delivery. Each tank comes as a complete construction package, including all necessary installation materials (excluding tools). Our custom-made silos are supplied standard with cord, protective fleece, clamp profiles, and the Install+ fixing system. We can also prefabricate outlets in your desired diameter and weld them into place at the specified location.

With our construction kit, assembling the silos requires only basic labor and a few simple tools. Thanks to their durable materials, compact shipping, and straightforward installation, our modular tanks are ideal for export and global use. Every tank comes with a comprehensive instruction guide to ensure easy setup.

Strict norms and standards apply to nearly all water storage applications, where maintaining water quality and ensuring safety are paramount. We are KIWA certified for processing films, adhering to rigorous safety and quality standards, including ISO 9001, CE, and VCA certifications. These certifications ensure that we can process plastic films both in our production facility and on-site, all under strict compliance.

We have thoroughly tested all steel configurations using advanced calculation models, ensuring a minimum safety tolerance of 40%. This means our steel constructions are 40% stronger than the required strength for water storage, providing added durability and reliability.

At NPI, quality and continuous improvement are always our top priorities. In fact, we often exceed regulatory requirements by implementing additional procedures. Through our certifications, rigorous quality control measures, entry and exit protocols, and comprehensive testing, we ensure consistent, high-quality products. The result? Reliability you can trust, every time. At NPI, we guarantee:

AEO – Expert in export!
At NPI, we place great emphasis on ensuring the efficiency and reliability of our shipments. Our Authorized Economic Operator (AEO) certification reflects this commitment, offering significant benefits to both NPI and our clients in international trade. With AEO certification, we face fewer physical and administrative inspections, and our shipments receive priority during certain scan checks. This results in faster processing times and reduced administrative costs. As an AEO-certified company, NPI has proven to be a trusted and reliable export partner!

CE
The CE marking serves as a clear indicator that a product complies with EU legislation. It signifies that our products have been rigorously tested to meet EU laws, ensuring they are safe, high-performing, and meet environmental standards. As part of this compliance, we are required to issue Declarations of Performance (DoP) for relevant products. NPI BV provides DoP declarations for our ENPEX FPP films. You can view or download these declarations as individual PDF files on this page.

Our high quality water storage solutions should not be at the expense of the environment, we believe at NPI. We value sustainable choices and prefer options that have a lesser impact on nature. Which choices do we make?

Sustainability and environmental responsibility are core principles of our production. We are committed to continuously improving our processes and products to be more eco-friendly.

The positive impact of our steel water tanks is twofold. First, they offer a highly durable solution for long-term water storage. Second, they help build resilience against extreme weather events. With climate change, population growth, and pollution making clean water increasingly scarce, relying on groundwater is not a sustainable option—it’s costly, lower in quality, and harmful to ecosystems. By collecting and storing water, our tanks create buffers that ensure water is available when needed, reducing dependency on unsustainable sources. This reliable supply of fresh, safe water benefits communities, horticulture, agriculture, and the food processing industry—in a clean and sustainable way.

Choosing our steel water storage tanks is a smart investment. They provide unmatched reliability, durability, and flexibility, making them ideal for a wide range of applications. With our steel tanks, you’ll enjoy a custom, long-lasting solution that also supports sustainable water management.
