Underground GRP Tanks
Type ST underground tanks from the Trokotex Water Series feature a robust, ribbed construction specifically engineered for underground installation. Compared to traditional concrete tanks, they are significantly lighter while offering exceptional durability and a long service life.
Our underground tank range includes single-wall GRP tanks designed for the storage of:
Drinking water
Rainwater (stormwater)
Fire protection water
The professionally engineered and reinforced construction of Trokotex underground tanks ensures safe and reliable storage while eliminating the corrosion issues associated with traditional concrete and steel tanks. All tanks in the Water Series are manufactured from Glass Reinforced Plastic (GRP).

Underground tanks are typically manufactured as horizontal cylindrical vessels with dished end caps.
Available in a wide range of capacities, they are suitable for numerous applications, including the food industry, agriculture, municipal infrastructure, and industrial facilities. Their robust construction, combined with PZH hygienic certification for drinking water, guarantees long-term reliability and outstanding product quality.
Trokotex underground tanks can be manufactured according to our own engineering documentation or based on customer-supplied drawings and specifications.
Depending on site conditions, groundwater levels, and soil characteristics, tanks can be installed on: Reinforced concrete foundations, compacted sand-cement bedding, engineered soil backfill
Tank length is fully customizable and is generally limited only by transportation requrements.
The standard burial depth is 1,000 mm. Greater installation depths can be accommodated following consultation with our engineering team.
Standard underground tanks are available with the following internal diameters: 800 mm, 1,200 mm, 1,600 mm, 2,000 mm, 2,400 mm, 2,800 mm, 3,200 mm.
