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.

Inlet connections are made according to the project (1/2 “, 3/4”, 1 “, 2”) for the purposes of distribution of water or PVC pipes from DN 32 to DN 400 for gravity overflows.

The Roterra 1400 rainwater collectors are available in sizes from 2,200 l to 3,300 l.
