NOVELTY - A biogas capture and/or collection system comprises biogas capture and/or collection units to capture and/or collect all of the biogas generated in biogas generating chambers (BGC) by the degradation of waste received from sources of waste. The biogas capture and/or collection units are tubular conduits (40) operatively linked to the biogas generating chambers, and/or containers (canisters) removably linked to the biogas generating chambers and designed for reversible capture of the biogas generated in the chambers.    USE - As biogas capture and/or collection system for capturing and collecting biogas generated in biogas generating chambers, useful in gas utilization centers located at individual sources of water or at centralized location, for electricity production, as fuels, and for chemical synthesis (claimed).    ADVANTAGE - The biogas capture and/or collection units (BCCUs) capture and/or collect all of the biogas generated in the biogas generating chamber (BGC). The BCCUs can function as stand-alone units that are harvested on an appropriate periodic basis for the biogas stored in it. The BCCUs are structured such that they create minimal disruption to the operation of the BGC. The stored biogas can optionally be used on-site for a variety of applications including domestic applications. The BCCU is positioned and structured so as to exit the BGC through a slab on top of the BGC, thus preserving the integrity of the BGC, as the BCCU does not exit the BGC on its sides. The dimensions of the BGC are determined based on its application of use. In high-performance sewer system (HPSS), the majority of solids remain within the individual BGCs, that minimizes the peaking factor, and eases the sizing constraints and ensures that the HPSS is a smaller, less complicated sewer system with lower capital costs to install and maintain that a traditional historic sewer system (HSS).
