Black & Veatch is the designer and builder of a new, $35 million solids treatment system for the Liverpool Wastewater Treatment Plant in Medina County, Ohio. The system provides energy performance savings and other sustainable benefits through an innovative Design-Build Performance Contract. As a result, the county expects to be able to pay for the new system without increasing customer rates. “The Liverpool plant’s existing sludge heat treatment system is more than 40-years-old and extremely expensive to operate,” said Blake Childress, Black & Veatch Project Director. “Its new solids treatment system will reduce annual operating costs by approximately 50 percent, for a projected annual operating expense of $1.656 million, and recover essential resources for sustainable reuse.”
Built into the system are advanced technologies that are new or emerging in the United States. They significantly reduce energy and construction costs, and enable Medina County to remove, and recover, phosphorous.
“The county’s unique project requirements and strict budget meant we had to look beyond traditional U.S. technologies and apply our global capabilities and knowledge base,” said Childress. “Drawing from our work in the UK and other sites in North America, we developed a solution that met Medina’s budget, performance and other project objectives.”
