Flat tanks F-Line

Flat tanks for rainwater o sewage

The Fline tank from Rewatec is an underground, flat tank for rainwater, municipal waste water or chemically aggressive waste water. The tank is characterised by its high strength and durability. It is possible to cover up to 1.5 m of ground level with soil. It is possible to install the tank in the area of car traffic using a suitable set for car traffic. The entire tank can be installed in ground water without additional reinforcement. Manufacturer's tests confirm the 100% watertightness of the tank - warranty 25 years. F-Line is made of environmentally friendly polyethylene (PE - MDPE) using the rotomoulding method. The tank has a monolithic structure (one piece), has no seams or welds, which makes it extremely resistant to the effects of the external environment (it does not crack, deform, bulge or break). The excavation for the installation of the F-Line tank is much shallower compared to traditional tanks, which reduces costs and facilitates the foundation of the tank.

Every Rewatec underground rainwater tank (our offer includes the BlackLine tank or the NEO tank) is subjected to intensive quality control after production. In addition, the tanks are subjected to pressure testing using complex and extreme loads simulating conditions in the ground. 

We also offer complete sets for using rainwater in the garden: GARDEN STANDARD SYSTEM WITH F-LINE TANK
