500-litre mini underground tank

This compact underground tank is just right for those who do not need as much water, but still want to save their rain water underground. The mini underground tank, too, is seamlessly moulded in one piece from black, food-grade PE plastic, very thick-walled and extremely dimensionally stable. A real Speidel tank, in fact.

Its large 55-cm manhole chamber has a 48-cm opening. The green tank cover can be screwed on, it is double-insulated and has a
stainless steel, child-proof lock.
