The activator is composed of a chamber generally listed below the ground. It has an inlet for inputs (mostly human excreta) and 2 electrical outlets (one at the centre for biogas, and the various other on among the sides for electrical outlet of sludge). Addition of animal manure and vegetation will improve the efficiency of the reactor.




If adequate wastes are generated, specific homes can each have one and obtain the advantage of biogas production. In bigger towns and cities, liquid waste may be conveyed by means of a sewerage network to a centralised wastewater therapy plant; for example, Addis Ababa's waste is dealt with at the Kality Wastewater Treatment Center.
