Biodigester sewers use a technology that allows living organisms or digesters act on human waste to break it down over time to useful substances and filters the liquid waste away through micro-sized sewer constructions. The advantages of the technology include: ●It has a 25-30 years guaranty and may well exceed that duration. ●It is cost effective, saves land space, energy, time, and other resources. ●It can be done in a house with an existing man-hole, the inlet pipes can be diverted to the digester box and the soakaway would no longer be necessary.
