Roterra rainwater collectors are made of nature-friendly polyethylene (PU) material and are designed for burial in the ground. Access to the inside of the reservoir is provided by flat hinged covers with a diameter of 600 mm with opening on a hinge, which are mounted on a telescopic lift, which allows easy adjustment of the tank trench to the terrain. A seal is installed on the lid to ensure watertightness.

The Roterra 1800 rainwater collectors are available in sizes from 3,500 l to 6,000 l.
