The city of Longview, in the US state of Texas, has held a ceremony to officially unveil its wastewater cogeneration project, which is scheduled for completion by the end of September.

City officials were able to fund the new cogeneration power plant and energy efficiency upgrade at the Grace Creek facility through a US$781,900 Energy Efficiency and Conservation Block Grant (EECBG) from the US Department of Energy (DOE) via the Recovery Act.

The city also provided approximately $300,000 in matching funds.

To cut emissions and reduce energy usage, the Wastewater treatment facility will capture the methane gas byproduct produced by the treatment process and convert it into electricity to help run the plant.

The electricity produced will be routed back into the wastewater treatment plant’s grid or sold to the utility American Electric Power (AEP) or the Southwestern Petroleum Corporation (SWEPCO).
