1500 Litre Garantia Lilo Underground Water Tank


Delivery Is Included In The Price. The Garantia Lilo Underground Tank Range is only available for Sydney Metro Delivery at the moment.

With a 1500 litre capacity, the innovative Garantia Lilo tank range by Graf is specifically designed for storage underground, providing all the extra water you need, conveniently and economically.

Tanks are typically buried out of sight beneath a driveway or under your front or rear lawn, which also helps to keep the water cool.


Due to the Lilo Flat Rainwater Tank being underground, no rain or sunlight can penetrate it – keeping the water storage free from UV and reducing temperature fluctuations.


Underground water tanks can be used for water retention.


Suitable for vehicle loading (up to 3.5t) when installed with separate class B cast iron lid.*

*Adequate drainage system may be required if groundwater is present. Contact Kingspan for further information.
