Addition of animal manure and greenery will enhance the effectiveness of the reactor.



If adequate wastes are generated, individual houses can each have one and obtain the advantage of biogas production. In bigger communities and cities, fluid waste might be conveyed via a sewerage network to a centralised wastewater treatment plant; for example, Addis Ababa's waste is dealt with at the Kality Wastewater Treatment Facility.
