The San Antonio Water System (SAWS) Water Resources Integration Program consisted of 45 miles of 48″ to 60″ steel pipe and two pump stations to ultimately convey water between four aquifer sources. Pape-Dawson was responsible for the design and permitting of Segment 1, a 60″ pipeline that begins at the Twin Oaks Water Treatment Plant in Southeast Bexar County and extends approximately 15 miles to the northwest. We provided a preliminary engineering report, alignment studies, topographic and tree surveys, environmental studies, permitting, design, and related construction support services.
The two-phase construction project will ultimately convey up to 75 MGD of potable water from four different sources: the Twin Oaks, Wilcox, Carrizo, and Edwards aquifers. The system will transport water into the distribution system during production mode and reverse flow to inject water into the Aquifer Storage and Recovery facility while in recharge mode.
