Use rainwater,
Secure the future.
Rainwater storage tanks and shallow water tanks ranging from 900 to 65,000 liters for residential, commercial, and industrial use.
The right solution for every project.
Rainwater is a valuable resource. With ROTO’s rainwater tanks, which can be installed above or below ground, rainwater can be efficiently collected, stored, and used in the home, garden, or for commercial applications. Underground installation saves space, protects the water from light and temperature fluctuations, and allows for large storage volumes without visible equipment in the garden.
ROTO offers a wide range of underground and above-ground rainwater tanks for various requirements – from compact solutions for single-family homes to large-volume tanks for industrial, agricultural, or municipal applications.
With the underground tanks RoCube, Robox, Roterra and RoDrive, ROTO offers a wide range of rainwater storage tanks for various requirements.
The high-quality plastic tanks (polyethylene) impress with their stability, long service life, and easy installation – for sustainable and economical rainwater harvesting.
