The Marsh Horizontal Septic Tank (4500L) is an ideal solution for small developments seeking a simple and economical means of wastewater treatment. With a CE accreditation for hydraulic efficiency at 99.63%, this tank effectively holds sewage, enabling the settling of solids into sludge, which are naturally broken down through anaerobic digestion.

Suitable for all ground conditions, its heavy-duty shell ensures durability, while integral lifting eyes improve on-site handling. The 'keying-in' feature aids anchoring into granular or concrete surrounds, and a pedestrian cover is included as standard for added convenience. Although it provides substantial settlement and some biological treatment, further treatment is required before discharge to the environment.
