Lawton WWTP Improvements

Working alongside the City of Lawton, Garver developed a conceptual engineering report and phasing plan to strategically reconfigure the Lawton Wastewater Treatment Plant (WWTP) over both the short term (2-3 years) and long term (10-15 years) planning horizons. With a combination of new and refurbished elements to transition the existing plant to a more modern facility, Garver’s team will create detailed plans for the estimated $85M worth of Phase I construction improvements. These improvements will also build toward the long-term phasing plan that will include expanding the plant’s biological treatment capacity from 18 MGD to 24 MGD over two additional phases.

Due to the significant financial cost associated with constructing a completely new treatment facility, short-term improvements will be necessary to keep the existing facility operational and build toward the ultimate solution until funding is in place for the future phases. The Phase I Improvements are anticipated to include a new administration and operations building, new mechanical screening, a new grit removal structure, and a new influent pumping facility, as well as rehabilitation of the trickling filters, solids thickening and dewatering facilities, and digestion complex.

Further, Garver will design new electrical services facilities, including a backup power generator system, two new electrical substations, and a complete rehabilitation/replacement of the plant’s SCADA system.
