GRAF Garantia Lilo 1500L Flat Underground Tanks Perth

The GRAF Garantia Li-Lo 1500L Underground Tank is a compact, German-engineered solution for efficient rainwater harvesting with minimal excavation. Designed specifically for shallow installations, the Li-Lo series reduces installation depth and cost—saving both time and labour on-site. Its flat profile requires up to 80% less digging than traditional cylindrical tanks, making it ideal for space-restricted or urban areas.

Despite its lightweight construction (just 80kg), the Li-Lo tank boasts exceptional structural strength. It remains stable in groundwater up to the shoulder without needing concrete anchoring. When paired with the optional telescopic dome shaft and cast iron lid, the tank is also suitable for vehicle loading applications.

Perfectly suited to WA conditions, the Li-Lo 1500L can also be made vehicle-loadable with the optional Telescopic Dome Shaft and Cast Iron Lid, making it ideal for driveways and trafficable areas.
