JUMBO BLOCK® is an innovative, modular system for underground rainwater retention and water storage, developed by the ZANNI GROUP. It offers exceptionally high storage capacity with minimal space requirements, setting new standards in sustainability, load-bearing performance, and global applicability.
Maximum Storage with Minimal Footprint
Each JUMBO BLOCK® module is a cube measuring 2.5 m x 2.5 m x 2.5 m, capable of storing up to 13.9 m³ of water. The modular design allows the creation of large-scale storage systems for cities, industries, agriculture, and critical infrastructure – all with minimal land use.
The modules are installed underground, making the surface above them available for roads, parking lots, green spaces, or buildings.
Sustainability & Environmental Friendliness
Unlike plastic-based systems, JUMBO BLOCK® is made entirely of high-strength concrete – no microplastics, no chemical leaching, and no environmental degradation. The system is fully recyclable, built for over 100 years of durability, and supports natural infiltration and groundwater recharge.
Modules can be equipped with advanced IoT technology such as LoRaWAN® sensors and IOTA Tangle architecture, enabling real-time monitoring and efficient water management.
Global Applicability & Future-Readiness
Designed for all regions and climates, JUMBO BLOCK® adapts to both urban and rural areas, flood-prone zones, and water-scarce regions.
It provides scalable resilience for a wide range of applications:
