Why check for lead?
SAWS is investigating lead in customer-owned water service lines as part of a new program required by the U.S. Environmental Protection Agency (EPA).
What is a water service line?
The service line is the piping that connects a home or business to the public water system. It is usually buried in the yard. The customer-owned service line, located between the water meter and the home, is the property of the homeowner and not part of the public water piping system maintained by SAWS.

We need your help to complete San Antonio’s water service line inventory. If your property is listed as unknown, we would like to partner with you to determine the material.

Exposure to lead is a well-known public health risk, especially for young children and those with other health issues.
Since the 1980s, SAWS has proactively replaced older pipes in the public water system that were made of lead.
We also conduct thousands of tests each year to make sure the water we deliver to your home or business is safe and secure.
