Underground
Underground tanks are perfect for building blocks where access is tight and room is limited.
The Garantia Li-Lo range of flat rainwater tanks are specially developed for rainwater harvesting. The range consists of 1500, 3000 and 5000 litre water tanks. It features a minimum installation depth and can be installed under driverways (additional fittings required) with a vehicle loading of up to 3.5tons.
We also have underground tanks ranging from 1250 litres to 3000 litres in a one piece design.
