GARANTIA Quality


Everything can be integrated into the tank

Filter rainwater directly in the tank and then use it for watering the garden and/or your domestic water system. GARANTIA offers you various solutions for filter systems and rainwater harvesting. Due to the integrated filter technology, no separate filter shaft is necessary. Installation is quick and easy, without tools.


Tank covers

Whether as a green plastic cover for pedestrian loading or in the version suitable for vehicle loading made of cast steel for installation under the driveway – GARANTIA offers you the right cover for every installation situation.


Connection surfaces

All GARANTIA underground tanks are prepared ready for connection in combination with the telescopic dome shaft and allow immediate installation. Tanks and shafts have pre-fitted sealings


Simple installation

GARANTIA underground tanks allow easy handling due to their relatively low empty weight and yet offer the necessary stability in the presence of groundwater.
