Products

Factory not connected to City main sewer, as it is not on zoned industrial park

Currently the 224 Cu. Meters of waste water produced per day is disposed on dug out ponds.

Slurry removal from sedimentation tanks cumbersome.

As production ground gets choked with the water this method of disposal is not sustainable.

Hence the need for a proper waste water disposal system.

Sedimentation Ponds:

BIL approached the University of Dar es Salaam to find solution to the wastewater problems in 2009

This was because we heard that they have been working on waste water treatment systems especially constructed wetlands

UDSM suggested energy generation combined with polishing in a constructed wetland

BIL and UDSM applied for Bio-innovate funding
