Crowder Constructors, Inc.

Scope Of Work

The R.M. Clayton Wastewater Treatment Plant is one of the largest wastewater treatment facilities in the Southeast. It has a permitted capacity of 100 MGD and a current average flow of 70 MGD, including both primary and secondary treatment unit processes. Crowder was contracted to perform this design-build, cogeneration project that provided a means to capture the energy potential in the digester gas and convert it to electrical power and thermal energy. The electrical power provided some offset for the current power usage at the facility. Crowder was responsible for the design, installation and start-up of major project elements including one biogas-fueled internal combustion gas engine generator, the combined heat and power process to recover thermal energy used in digester operation, and electrical facilities connecting the engine-generator equipment to the electrical power grid.
