5,000-litre flat tank

Speidel's underground storage tank is also available as a flat version. Especially in rocky terrain or if the pit is to be dug by hand, the flat tank is the best choice, because in this case there is considerably less excavated earth than in the case of normal underground storage tanks.

This model, too, has everything that distinguishes a Speidel tank: It is seamlessly moulded in one piece from high quality, food-grade PE plastic, very thick-walled and extremely dimensionally stable. Its large manhole chamber has a diameter of 55 cm and an aperture of 48 cm. The green tank cover can be screwed on, it is double-insulated and has a stainless steel, child-proof lock.
