- 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
