Bio Sewage Systems are modular in design and each sewage treatment plant is tailor-made to each customer’s requirements.

The smallest available unit, Flush n Spray® a 2 cube plant, can treat up to 2,000 litres of black and grey water per day, the largest plant is the “BioBEE500”, a 500 cube plant, which treats up to  500, 000 litres of waste water per day.
