Klargester BioFicient sewage treatment plants are specially designed for shallow dig applications, with its low profile cover and adjustable extension neck saving on-site installation time and cost. It also offers low running costs, high performance and low maintenance.

Like the BioFicient 4, the BioFicient 5 model has 2 covers (1500mm & 900mm cover sizes) but is suitable for properties and applications of up to 20 inhabitants. This makes it suitable for small housing estates consisting of multiple properties.

Suitable for trafficked areas (structural advice needed depending on expected load - contact JDP for further details), the BioFicient 5 is manufactured from glass reinforced plastic (GRP).
