Wastewater Treatment Plant Improvement Projects & Travisso Water Reclamation

GBA provided engineering services for this project that included surveying, design, bidding and construction phasing.

• Filter Improvements– This project provided tertiary filter improvements to the FM2243 wastewater treatment plant. The City of Leander desired to upgrade filter technology to replace the aging traveling bridge sand filter. A unique approach for these improvements consisted of a retrofit of one of the two existing traveling bridge sand filter units with the installation of five new disk filter units. The design eliminated the need for new structures and piping outside of the existing plant chambers by incorporating all new equipment within an existing filter chamber.
• Aeration Improvements– This project provided supplemental aeration capacity to the FM2243 wastewater treatment plant. The project consisted of the design and installation of two blower-assisted mechanical aerators and associated equipment and electrical improvements.
• Travisso Water Reclamation Plant– The project included two lift stations, a 0.25 MGD water reclamation plant, 14 MG reclaimed water storage pond, 1,050 gpm reclaimed water pump station and a 12” diameter raw water makeup system for the Travisso master-planned community. The systems were designed to be expanded in two additional phases to reduce up-front capital costs and allow for system capacity expansions to meet growth and project build-out.
