Underground HDPE and PP Tanks with Cylindrical  Spiral-Wound Walls, in Single Wall or Double Wall Construction


Monitored underground tanks represent an important development for safe underground storage of hazardous liquids. Underground tanks must be designed and installed in accordance with water conservation and building regulations. formoplast tanks feature an annular void space which is constantly monitored for airtightness. In the event of damage to the tank, a leak detection system immediately triggers an alarm.
