Benefits easier and quicker installation, low installation costs small pit and small amount of excavated earth, less disturbance to the garden ideal for retrospective installation on existing properties car-driveable can be installed in groundwater up to tank shoulder 25-year guarantee optimal use of tank volume thanks to pump basin The F-LINE underground tank is notable for its extremely flat construction which means an installation depth up to 60% lower and an excavation pit of up to 70% less compared to other tank types. Low installation depth automatically means less work, fewer suprises (e.g. critical soil layers or rock) and thus lower costs overall. Installation-comparison garden unit The installation depth for a garden unit comes in at 100 cm for tank types FT 1500 & 3000 l and only about 135 cm for tank type FT 5000 l. So based on the DIN 4124 standard, neither working tolerance nor slope incline are required. And the advantages in terms of excavation are obvious. The FT 5000 l flat tank means shifting only 10.4 m3 of earth, compared to a massive 40 m3 of earth for a 5000 litre cylindrical tank.
