To expand its water supply portfolio over the next 11 years, the San Antonio Water System (SAWS) will deliver a phased program that will provide the county with over 30 million gallons per day (MGD) of additional drinking water production capacity.
 
The Phase I facility will produce 12 MGD of finished water from 2 MGD of filtered well water blended with 10 MGD of reverse osmosis (RO) permeate water. SAWS will complete Phases II and III, in 2021 and 2026 respectively.
 
The Phase 1 project manager is Black and Veatch, the process design engineer is Tetra Tech, the construction manager at risk (CMAR) is Zachry-Parsons and the mechanical contractor is Dynamic System Inc. Biwater was selected as the reverse osmosis system supplier for the project and will be responsible for the RO trains, design of ancillary equipment as well as the RO system operation philosophy.
