Underground tanks

The right rainwater harvesting system

Speidel's indestructible underground tanks tanks are made out of high-quality PE-plastic and therefore suitable for drinking water storage. Massive reinforcement ribs and the thickest walls of all PE-rainwater tanks make these cisterns extremely robust and stable in form. The underground tank RTMO is available from 2,000 litres up to 10,000 litres storage capacity. The flat tank is available with either 2,500 or 5,000 litres capcity and the mini underground tank is available in versions of either 500 or 1,000 litres.
