Biogas Wastewater Assessment Technology Tool (BioWATT)

Developer or Source: Global Methane Initiative (GMI)

Biogas Wastewater Assessment Technology Tool (BioWATT) provides a quick and preliminary assessment of wastewater-to-energy projects. Includes: (1) biogas production estimate for various wastewater-to-energy technologies, (2) electricity generation potential from the produced biogas, (3) greenhouse gas savings associated with biogas-generated electricity, (4) preliminary assessment of the wastewater treatment facilities electricity demand that can be met through biogas-generated electricity; (5) preliminary design parameters of major components of a wastewater-to-energy project, such as required digester volume, required gas holder volume, and total combined heat and power (CHP) electric power output, and (6) impact on a wastewater treatment facility operating expenses (OPEX) by investing in energy generation technology
