San Antonio Water System is committed to making sure our water and wastewater delivery systems meet the highest standards of safety and quality that our community expects and deserves.

Critical construction projects are underway throughout San Antonio as SAWS continues its ongoing preventative maintenance and repair of the city's water and wastewater infrastructure.

Until recently, the rate of infrastructure replacement was only enough to change out each pipe, pump and manhole once every 200 years. Thanks to recent improvements in planning and efficiency, we are now moving toward a more aggressive replacement cycle – one more in line with the 70-80 year potential lifespan of most larger mains.
