RoTerra rainwater tanks are made of nature-friendly polyethylene [PE] material and are intended for burial in the ground (underground installation). Access to the inside of the tank is provided through a PE cover with a diameter of DN600, which is mounted on a telescopically adjustable height with the possibility of easy adaptation to the terrain. A seal is installed to ensure watertightness.

Inlet and outlet pipes (connections) can be made according to the project with PVC pipes from DN 32 to DN 400 or more with gravity overflows or with PE pipes (1/2'', 3/4'', 1'', ...) with pressure pipes.

Rainwater tanks RoTerra are available in sizes from 2200 L to 50000 L.
