San Antonio Water System has long been committed to protecting and preserving our most precious resource.

Since 2013, SAWS has engaged in proactive efforts to reduce non-revenue water — water that was produced or received from various sources, but never delivered or billed to a customer.

Non-revenue water is sometimes referred to as “water loss,” but that term can be misleading. While non-revenue water does include water “lost” through main breaks and leaking infrastructure, it also includes unbilled water use due to:

Authorized consumption

  • Hydrant flushing
  • Firefighting
  • Water line flushing for health and safety
  • Water used for sewer system cleaning and maintenance

Apparent losses

  • Inaccurate meters at homes and businesses
  • Water theft
  • Data errors

In 2024, the SAWS Board of Trustees initiated a renewed focus on water stewardship, to ensure customers receive the best value possible for their monthly water bill payments.

After a series of intensive Board work sessions, a task force of 18 key SAWS leaders from across the utility was assembled to initiate, plan and execute a comprehensive water stewardship program.

The task force identified accurate measurement as the first step toward controlling and ultimately improving non-revenue water loss, accomplished by:

  • Improved water production metering at the source
  • Enhanced customer metering via ConnectH2O electronic meters
  • More accurate estimates of water lost through breaks and leaks
  • Better estimates of unbilled-but-authorized water use such as firefighting and line flushing/cleaning

2025 Water Loss Interventions

In addition to improvements in measurement outlined above, SAWS is committed to reducing “real” water loss through:

  • Proactive leak detection
  • Improved response time to repair leaks and breaks
  • Exploring new technology
  • Prioritizing water main replacement projects
