Brief Loss in Pressure in South Bexar County Triggers Boil Water Notice

 The combination of a water main break and closed valves near Loop 1604 and IH 37 south caused a loss of pressure to customers south of Loop 1604 near the Waterwood subdivision along Priest Road.


Service has already been restored, however State law requires that after pressure is restored and the system is cleared, water samples must be taken to confirm the water is safe, which will take approximately 24 hours.

SAWS has completed phone notifications and social media announcements to customers in the area.

While SAWS has every expectation that water in the area is safe, as a precaution, customers are urged to follow boil water procedures (see attached) until test results are back late Wednesday.


Boil Water Notification

SAWS PWS – 0150018 and 0150249

May 28, 2019

A main break early Wednesday morning near south Loop 1604, combined with water valve closures caused a drop of pressure in the potable water. Required water pressure of 20 psi was unable to be maintained. In this situation, The Texas Commission on Environmental Quality (TCEQ) requires utilities to notify customers in the affected area to boil water prior to consumption.

SAWS has already reestablished pressure in the system. While we have every expectation that water in the area is safe to drink, we urge customers to follow boil water procedures out of an abundance of caution until test results are back sometime on Wednesday.

Two gallon containers of bottled water per household are available at the following locations:

Entrance to Waterwood subdivision on Priest Road

Northeast corner of IH37/1604 across from Bill Millers


To ensure destruction of all harmful bacteria and other microbes, water for drinking, cooking, and ice making should be boiled and cooled prior to consumption. The water should be brought to a vigorous rolling boil and then boiled for two minutes. In lieu of boiling, you should consider bottled water or obtain water from some other suitable source.

We appreciate your cooperation and will notify you when the required state tests confirm that the boil water notice is no longer in effect.  If you have additional questions, please feel free to contact these individuals:
