1000 mm (39.4 inch).


Under no circumstances are occurring loads to be transferred directly to the tank.
The Li-Lo Rainwater Underground Tank may under no circumstances be installed in areas traversed by
heavy goods vehicles or heavy machinery (See point 5.2.3).

6.4   Assembling the extension riser as adapter
If a wider dome shaft  is used as shaft extension or adapter for larger earth coverage, it is fitted loosely
between the tank opening  and the top extension riser . The shaft extension gains its final stability
without further fastening when the pit is filled up and compressed.
The maximum effective length per shaft extension or adapter is 406 mm (16.0 inch). The dome shaft can
be shortened at 7 positions from top by 50 mm (2.0 inch) in each case (see sketch).
The maximum allowed earth coverage height in combination with a second GARANTIA extension riser is
1200 mm (47.2 inch) above tank shoulder (only in green areas – not in the areas used by passenger cars.
