ET tanks

Underground rainwater or sewage tanks

Polyethylene tank intended to collect rainwater and municipal waste water. All rewatec tanks are made of ecological polyethylene (PE). With the formation of the rotation, we managed to achieve unmatched strength and highest stability tanks. Due to the monolithic structure (one element), the reservoir ET is 100 % watertight. Thus we achieve lasting protection against fracture or rupture the tank. It is therefore a safe investment for decades. All tanks Rewatec after manufacture are subjected to intensive quality control. In addition, the tanks are subjected to selective pressure tests using complex and extreme loads simulating conditions found in the ground. Thanks to the unique design of the tank is durable, can be placed in a circular motion. The reservoir of elongated shape and low high. This makes it particularly easy during installation, plus additional saves during the foundation earthworks.
