Area engineering companies honored for work

By NEMS Daily Journal

Murphy Engineering of Guntown and Jenkins Engineering of Tupelo were honored with the top award at the 2013 Engineering Excellence Awards ceremony for the American Council of Engineering Companies of Mississippi.
The two companies, together with Mid-South Consulting, a consulting firm with offices in Florence, Miss., and in Memphis, won the Grand Conceptor Award at the meeting for their Waste-to-Energy project at the Three Rivers Regional Landfill in Pontotoc. The three firms designed the project.
The project was one of the first landfill gas to energy projects in Mississippi and the only facility in the state that removes siloxanes from the biogas.
The project utilizes methane generated from solid waste decomposition within the landfill to fuel a 1 megawatt generator. The power produced by the generator is sold to the Tennessee Valley Authority and Pontotoc Electric Power Association under a 10-year agreement as part of the TVA’s Green Energy Partnership Program. Power generated from the facility is capable of providing electricity to approximately 800 residential homes in the community.
This project is unique because the design, construction and operation of the facility were not mandated by any federal, state or local regulations nor subsidized by government funds. These conditions made it absolutely essential that the overall project be financially sustainable and operating in the black throughout the life of the project.
The project generates approximately $1 million/year in revenue, which is more than adequate to pay for principal and interest payments and day-to-day operations and maintenance expenses. The project also contributes more than $100,000 a year to the closure and post-closure fund of the landfill, which assists the Three Rivers Solid Waste Management Authority in keeping user fees and operational costs low for the residents and businesses within the seven-county planning area served by the landfill.
