Underground Storage Tanks

Underground storage tanks are designed for safe and long-lasting liquid storage in confined spaces, providing solutions suitable for below-ground use. At Tempo Kompozit, we manufacture custom GRP underground tanks tailored to site conditions and the properties of the stored fluids.

Made from GRP material, these underground tanks offer superior resistance to soil moisture, chemical interactions, and harsh environmental conditions. Unlike concrete or metal tanks, GRP tanks do not suffer from cracking, corrosion, or leakage over time.

Tanks are designed according to static calculations, considering soil loads, groundwater levels, and external pressures. When necessary, external reinforcements and special rigidity layers are applied to enhance structural strength. They can store wastewater, rainwater, process water, and various chemicals, and can be manufactured as monoblock or modular units. Their lightweight construction allows for easy transportation and installation on site.

Filling, discharge, ventilation, and level control points are designed according to project requirements, along with manhole covers and connection nozzles. Special sealing and odor-control cover systems can also be integrated upon request. With long service life, minimal maintenance needs, and safe operation, GRP underground storage tanks provide an economical and sustainable solution for infrastructure projects, industrial facilities, and municipal applications.
