Peachtree City Water and Sewerage Authority is accepting proposals for design-build services for wastewater treatment facility improvements. The project generally consists of the following improvements: installation of a new UV disinfection system at the Owner's two wastewater treatment facilities, Rockaway WPCP and Line Creek WRF; design and construction of an additional secondary filtration system at Rockaway WPCP; and installation of a new headworks bar screen at Line Creek WRF. Equipment has been pre-selected by the Owner. Design-build services will include both pre-construction and construction services.
