ABSTRACT:
A sewage gas collection reservoir is provided with a valve and distribution system. Combustible gases are produced by anaerobic bacteria in mixtures of organic matter which are trapped by the cone shaped reservoir at the top of the mixture from which the gas is drawn past a valve, then past a water trap, then past an activated charcoal filter and fed into an ordinary household gas line by the vacuum created by the flow of the household gas supply. A one way valve is provided at the activated charcoal filter to prevent a reverse flow into the system and reservoir.
