The San Antonio Water System (SAWS) will deliver a phased program in the next 11 years to expand its water supply portfolio.

The program will provide the county with more than 30 million gallons per day (MGD) of additional drinking water production capacity.

The new brackish desalination plants will reduce the population’s reliance on a primary drinking water aquifer.

Phase one of the facility will produce about 12 MGD of finished water from 2 MGD of filtered well water blended with 10 MGD of reverse osmosis (RO) permeate water.

SAWS is planning to complete the second and third phases in 2021 and 2026 respectively.

Black and Veatch is serving as the project manager for the phase one while Tetra Tech is the process design engineer.

Biwater will deliver reverse osmosis system for the project and be responsible for the RO trains, design of ancillary equipment as well as the RO system operation philosophy.

Biwater desalination and membrane treatment sector president Jorg Menningmann said: "This project award builds on our prior accomplishments in Texas. Our membrane technology expertise will be instrumental in ensuring that the first phase of this project delivers results ahead of SAWS embarking on latter project phases over the next 11 years."
