Any company that manufactures a product will have wastewater and process water from its processes. In industries, wastewater and process water are stored to create a buffer and to manage and treat it properly before discharge or reuse. For a facility it is important that the water storage capacity is accurate, reliable, safe and that it meets the required regulations.
Many NPI water tanks are used across various industries worldwide as storage solutions for wastewater or process water. Industries include water treatment and the agrifood sector, such as dairy and meat processing plants, as well as canning, production and preservation facilities for oil, vegetables, beverages, fish, starch and more.
Process water storage tanks
Process storage tanks are essential for storing and treating wastewater generated from various processes in industries. NPI steel water tanks are designed to safely store wastewater. Our water tanks are constructed from corrugated MagiZinc® steel and are often used for large volumes of wastewater. The bottom rings are typically coated to ensure that the lower steel panels, which might come into contact with moisture or other substances, are extra protected.

The interior of the tank is lined with a premium lining material. These lining materials are food-grade, ensuring they are safe for contact with food products and other substances involved in the process. Our most commonly used lining material, ENPEX FPP, not only meets food-grade standards but also excels in chemical resistance, flexibility and durability. It guarantees safe and watertight water storage, while also protecting the steel from the chemical and corrosive effects of wastewater.
Advantages of process water tanks
Efficiency
Our tanks provide a high-quality water storage solution with a focus on efficiency, saving on costs and security. This way, our customers can rely on a continuous operation without having to worry about their water storage system.
Cost-effective
The high-quality materials, sourced from first-class suppliers, our unique production process, our in-depth knowledge of the industrial water market and our certifications guarantee consistent and superior quality water storage systems. This quality and efficiency ensure that our customers benefit from low maintenance costs and a water tank with a long lifespan.
Environmentally friendly
Water is costly and scarce, so industries need to conserve and reuse it. NPI water tanks support water recovery, including rainwater harvesting, and facilitate effective treatment for reuse in processes. They are a sustainable solution.

Considerations when choosing a process water tank
Location
Process water can vary widely in composition and volume during production. Whether you need to store large quantities of fresh water or small amounts of treated water, our water tanks for process water come in various capacities and diameters to suit any production facility.
Maintenance
Another consideration is the straightforward maintenance for our process water tanks. While maintenance is minimal and simple, it is essential for extending the lifespan of your water tank. Fortunately, we provide good guidance through our maintenance sheets, which explain what you need to monitor.
Site preparation
Modular tanks used for fire protection are installed on a concrete foundation. The metal walls of the tank are then placed on this foundation. Our instruction guide provides clear details on how to set up the foundation for a fire protection water tank.
Installation process
Installing the metal walls is straightforward; it involves fastening bolts and nuts. The metal walls are lined with protective fleece, and the liner, custom-made for each project, is supplied with cord and clamp profiles as standard, as well as the effective Install+ fixing system. We can prefabricate outlets in the diameter of your choice and weld them in place at the desired location. The compact shipping and simple installation of the materials make our modular tanks very suitable for export and installation even in very hard-to-reach places.

Maintenance
In general, NPI tanks require minimal maintenance, but regular upkeep is important. This extends the lifespan of a water tank and ensures that it meets safety and performance standards. Proper monitoring and maintenance of the various tank components are crucial, as the tank plays a critical role in emergencies and must function correctly. Our maintenance guide explains what needs to be done and how to periodically maintain your tank
In summary, our water tanks offer various benefits. As we produce each tank to measure, there is always a water tank that fits your facility and needs. Our tanks are built to last for years with minimal maintenance and allow you to store, treat and reuse water. With an NPI tank, you will get a reliable, durable and eco-friendly water storage solution.
