Southwest Bexar Sewer Pipeline

Journey into 32 miles of pristine tunnels

It spans about the same distance as from San Antonio to Pleasanton. You can even drive a small car through sections of it.

Besides its massive length, the Southwest Bexar Sewer Pipeline – a unique public-private infrastructure partnership – has another impressive quality: to support recent and future growth to the south and west sides of the county.

The pipeline, completed in 2014, snakes along the Medina River and ultimately link far west and southern San Antonio to the Dos Rios Water Recycling Center. It's a key component of SAWS' Capital Improvement Plan.

This project is an example of ratepayer dollars at work in our community. In a move that will open up new development in the far south and west portions of the county, the Southwest Bexar Sewer Pipeline provides a backbone for wastewater service in this area, ultimately capable of providing service to more than 250,000 people. In addition, the project will result in cost savings in other areas for ratepayers by eliminating at least 10 lift stations, reducing costs for upgrades and maintenance, as well as eliminating the need to expand other SAWS treatment facilities.

"The Southwest Bexar Sewer Pipeline will ensure that the far west and southern parts of our county can continue to grow by providing the necessary infrastructure for residents and businesses moving into the area," said Robert R. Puente, SAWS President/CEO.

The pipeline was constructed at a total cost of $103.5 million. The project includes 32 miles of large diameter sewer pipe, ranging from 36 inches to 96 inches, or 8 feet, in diameter.

SAWS has more than 12,000 miles of water and sewer mains under more than 550 square miles of service area – enough pipe to reach from San Antonio to Australia!

Now that you have the facts, journey inside the Southwest Bexar Sewer Pipeline and witness first-hand the enormity of the project.
