“Gresham Smith’s staff was very intentional with including all of the plant’s personnel in the design process and identifying and addressing our concerns and goals throughout the project. All aspects of the project were considered, including operational aspects, maintenance, cost effectiveness, constructability and flexibility. It was a team effort, which is evidenced in the final product. We are very pleased with the new facility and we are confident it will perform well for many years to come.”

Mike Gardner, P.E., Water/Wastewater Systems Manager, Bowling Green Municipal Utilities

“Gresham Smith's work on both our brownfield plant rehabilitation and our new greenfield wastewater treatment plant saved us on capital costs, but more importantly, will save O&M costs and extend asset life compared to more mainstream design solutions. Partnering with local design firms, Gresham Smith provided us with a cost effective alternative which has proven to be very beneficial to our ratepayers.”

Miguel Bordallo, Guam Waterworks Authority

“From the onset of the PACE10 program, KUB took an aggressive, systematic approach to addressing SSOs through a combination of collection system rehabilitation, off-line storage, increased conveyance capacity, and treatment optimization. In addition to reclaiming capacity and reducing overflows, improvements made during Phase I have enhanced our system’s overall performance. All of this was made possible by the hard work, professionalism and dedication of the KUB project team including the planning, design and construction management support and leadership provided by consulting partner Gresham Smith.”

Bill Elmore, Executive Vice President and Chief Operating Officer, Knoxville Utilities Board

“It was a great experience working with Gresham Smith on the Southside Wastewater Treatment Plant major maintenance project. Throughout the design process, the firm managed the project along with their subconsultants in such a manner that the project management and plant staff were continually updated and involved throughout the process. The Gresham Smith team delivered a project that was completed on time and construction bid was on budget.”

Leslie Castillo, P.E., Project Manager, City of Dallas

“Gresham Smith's staff worked well with the Public Works Department throughout the sewer rehabilitation design and construction to ensure Public Works' needs were addressed. The presence of the Resident Project Representatives has been the most important staffing aspect during construction. Their on-site presence is a lifeline and they are immediately available and responsive to field related issues.”

Allan Ellis, Director of Public Works, City of Springfield

“Gresham Smith staff, serving as the Construction Managers for the Clean Water Nashville program, have been prompt and responsive to the concerns of our constituents; this attention to detail has helped to minimize the escalation of concerns and positively promotes our Program in the community.”

Greg Ballard, Deputy Program Manager, Overflow Abatement, Metro Water Services
