Market leader in water storage

In the past decade, NPI has grown to become an international market leader in water storage systems, including metal water tanks. Specifically, we have used our technical expertise to become a specialist in modular metal water tanks with high-quality silo linings. We realise these water storage solutions for the horticulture sector and many other applications and markets. These include drinking water storage, rainwater storage, fish farms and manure storage.

Water storage tanks

Our water storage silos are a durable, modular choice that is popular across the globe. We manufacture these tanks from high-quality corrugated steel, which has very high structural stability and high tensile strength. We line the metal tank walls with a film. In addition, the water tank can also be completed with a cover and various accessories and connections.

Water tanks for agriculture

Our metal water tanks find their way to different markets, including agriculture. As a result, many NPI water tanks have been installed at farms, storing (drinking) water for livestock and poultry. Livestock producers, in fact, need a safe and reliable supply of good quality water for their animals. In light of this, rainwater harvesting is a good suggestion since collected rainwater can be used for drinking water or for other processes that are at play at farms. For this reason, our storage silos are a popular solution for farm water storage. Contact us for more information about agricultural water tanks.

Customised solutions

Every application and environment demands a different water storage type. Therefore, NPI produces metal water tanks to measure; we can adapt the dimensions, composition and finishing of the tank to suit the application, environment and the wishes of the client. For example, we can increase the steel thickness for extra strength or apply a coating to extend the lifespan.

Various modular metal water tanks types

  • Standard tanks (minimum 0.8 mm steel thickness)
  • Type A tanks (minimum 1.0 mm steel thickness)
  • Short panel tanks (reduces shipping costs)
  • Coated tanks (coating per ring possible)
  • E-range tanks (industrial, heavy duty tanks)
  • Fish farm tanks (special heights and silo linings)


We offer standard water tanks in a wide range of standard heights and diameters. That is to say, the diameter of the tank can vary from approximately 1 to 32 metres, with a height of approximately 1 to 5.5 metres. This allows customers to opt for storage capacities of up to 2,000,000 litres. Additionally, tanks with specific dimensions are no problem whatsoever: our advisers would be happy to discuss your wishes.
