Type ZP – GRP underground tanks – durable solutions for water and fluid storage
Underground tanks type ZP of the WODA series are characterized by a robust, ribbed structure that allows them to be buried in the ground and much lighter weight than concrete tanks, and above all, many years of service life. In the group of underground tanks we offer single-walled tanks for drinking water, rainwater (precipitation water), water used for firefighting purposes.
The expertly made and additionally reinforced construction of TROKOTEX underground tanks guarantees the safety of storing the medium and eliminates the dangers associated with storing it in tanks of other material design, such as highly corrosive concrete or steel. WODA series tanks are made of glass-reinforced plastic as standard.

GRP underground tank – the advantages of modern material technology
Choosing a GRP underground tank from TROKOTEX means investing in a product that combines mechanical strength with outstanding resistance to corrosion and chemical degradation. Unlike conventional concrete or steel tanks, GRP tanks are immune to rust, corrosion, and biological growth, which drastically reduces maintenance requirements and operating costs. Our WODA series grp underground tanks are certified for hygienic use and are suitable for applications ranging from potable water storage to rainwater harvesting systems. Their cylindrical, convex-bottomed design further enhances stability and optimises space usage underground.
Advantages and benefits
Underground tanks are usually cylindrical tanks with a horizontal axis enclosed by convex bottoms.
Thanks to the different capacities, the underground models available in our offer are used for various purposes, including in the food industry and agriculture. Robustness of workmanship and PZH (National Institute of Hygiene) certificate make them high-quality solutions.
The depth of downhole is 1000mm. Placement of tanks at a different depth by agreement with the manufacturer.
