  The affected area is generally north of Loop 1604 and west of U.S. 281 in and around the Stone Oak subdivision. Click to view full-size map.  

2 p.m. UPDATE:

After three days of intense work, the pipeline that is the primary source of water for the Stone Oak area has been repaired and is back in service. SAWS crews worked 48-hours straight to repair and modify the damaged pipeline. Finally, wells at the Bitters Road site that provide flow to Stone Oak were cranked up early Thursday morning, and water line flushing and quality testing ensured the water continued to be safe to drink.

“We would like to offer our sincere thanks to all the people in Stone Oak who helped reduce demand by turning off their outdoor watering,” said SAWS Vice President Mike Brinkmann. “With their help and the efforts of SAWS crews, we were able to maintain supply to the area. Everyone was very cooperative and helpful and this is just another reminder of what a great community we live in.”

In recent months, SAWS added connections between the former BexarMet service area in Stone Oak and the surrounding SAWS infrastructure. These connections were part of ongoing efforts that continue to make the integration of the former BexarMet into SAWS a success and infrastructure challenges such as these manageable.

Now that the emergency is passed, Stage 2 watering days and times are back in place. Homes and businesses with addresses ending in 6 and 7 can water tonight between 7 to 11p.m. Addresses 8 and 9 can water Friday 7 – 11 a.m. and 7 – 11 p.m. Hand watering is still allowed any day, any time.

7 a.m. UPDATE:

SAWS crews substantially completed repairs to the failed 48-inch water line supplying Stone Oak overnight. The pumps were started around 1:30 this morning and the system has run in a "flushing mode" overnight with no problems reported.

Flushing of lines will continue throughout Thursday morning.

Assuming all continues to go well, the ban on outdoor water use for Stone Oak area homes and businesses could be lifted before the end of the day Thursday. However, please wait for "all clear" announcement from SAWS (via news media, Facebook or Twitter) before starting any landscape irrigation.

4 p.m. UPDATE:

SAWS crews spent another day working on the failed 48-inch water line, originally constructed by BexarMet, that supplies most of Stone Oak. The area that experienced most of the damage has been excavated, and new parts are coming in from Houston to replace those that couldn’t be repaired.

Work that still needs to be done includes: assembling new and rebuilt parts, testing pump and connections, and flushing the water line.

Thanks to interconnects established since the two utilities merged, sufficient water pressure has been maintained to supply water for indoor water use. However outdoor water demand would critically reduce water supplies.

As a result, SAWS is extending the outdoor watering ban in Stone Oak through Thursday morning. SAWS off-duty police officers and personnel will once again be in in the Stone Oak area to ensure that business and residential irrigation systems are turned off.

6 a.m. UPDATE:

Repairs on this major main break will continue throughout the day Wednesday. Please, NO OUTDOOR WATER USE for ALL of Stone Oak, The Vineyard, Sonterra and Greystone until further notice. Indoor water use may continue as normal.

Multiple water system inteconnects constructed over the last 2 1/2 years since the former BexarMet became part of SAWS have maintained pressure to the area.

Curtailing ALL outdoor water use until further notice will ensure water continues to be available for all other uses until repairs are completed.

Prohibited outdoor water use includes:

  • Lawn sprinklers
  • Irrigation systems
  • Hand watering
  • Washing of sidewalks/driveways
  • Home car washing

SAWS crews will continue to work 24/7 until service is fully restored. We apologize for the inconvenience and appreciate your cooperation.

The primary water pipeline from the former BexarMet infrastructure serving the Stone Oak area is out of service due to a mechanical malfunction. Crews are making emergency repairs.

Water service in the Stone Oak area is currently being maintained through infrastructure that has been newly constructed and installed by SAWS since the merger with BexarMet.  Four interconnects around the Stone Oak area are now open and providing water service during repairs.

SAWS is committed to continued improvements of former BexarMet infrastructure.  Recent improvements to the former BexarMet infrastructure have made this service interruption manageable.

To help ensure continued water service, Stone Oak customers must discontinue outdoor water use. Irrigation systems should be turned off until further notice. This includes residential, business and public area systems, and medians.

Intensive work is being done to correct the problem, but assistance from SAWS customers is needed to avert further issues. Specific areas affected include The Vineyard, Sonterra and Greystone, but all of Stone Oak is being asked to discontinue outdoor watering until further notice.

SAWS is continuing to monitor repairs closely, and will provide updates via Facebook, Twitter and news media.
