-- McCarthy Building Companies Inc. in a joint venture with Black & Veatch was recently awarded a contract by the Trinity River Authority of Texas for the solids process improvements at the 162-MGD Central Regional Wastewater System in Dallas. The $152 million project, which focuses on overall comprehensive biosolids improvements, will utilize a thermal hydrolysis/anaerobic digestion process to break down biosolids for significant reduction in biosolids quantity leaving the plant with the added potential for beneficial reuse in the future. This anaerobic digestion process will require construction of 3 new digesters and their associated ancillary processes.
“This will be the first plant in Texas to utilize the thermal hydrolysis treatment process, and only the second plant of its kind in the country. This treatment process will significantly reduce the volume of solid waste produced from the plant, as well as create a more robust methane production, which provides the future opportunity to add a combined heat and power expansion to the plant,” said Tracy Kimnach, project director at McCarthy.
CDM Smith, the engineer for the project, designed a comparable thermal hydrolysis installation in Washington, D.C. This is TRA’s first alternative delivery project. “As the Construction Manager at Risk, our goal is to optimize project delivery by maximizing cost and schedule savings while ensuring the quality is delivered throughout this project,” Kimnach added.
s team of wastewater specialists bring expertise regarding constructability issues, planning and work sequencing to effectively maintain ongoing plant operations during construction, which allows us to successfully execute this project while working around the complex existing site constraints.”
The anticipated three-year project construction schedule began in December 2015 with completion slated for December 2018.About McCarthy Building Companies
