Far North Side Water Pressure Issue Triggers Localized Boil Water Notice

Area west of IH-10, neighborhoods Terra Mont & Stonewall Estates, near Babcock and Heuermann affected

SAWS officials have determined that an area of about 700 homes and businesses had water pressure that dropped below 20 psi overnight. As a result, SAWS is required to notify customers to boil their drinking water.

Neighborhoods affected by the issue are Terra Mont and Stonewall Estates.

SAWS is working to resolve this situation as quickly as possible.  SAWS will complete repairs and restore pressure before final samples are collected, and SAWS is authorized to lift the boil water requirement. Until the sample results confirm that water is safe to drink, customers are asked to boil water for drinking, cooking and ice making.

Boil water instructions are shown below.

SAWS will provide notice once pressure is restored, and final test results have cleared water for consumption.

If you have questions, contact the SAWS 24-hour line at 210-704-7297.

During a Boil Water Notice

When a boil water notice is issued and you need to use tap water, you must boil the water before: drinking it, making drinks, preparing food, brushing your teeth or making ice.

Official Notice Language

Due to a drop in water pressure below minimum standards, the Texas Commission on Environmental Quality has required SAWS to notify all affected customers to boil their water prior to consumption (e.g., washing hands/face, brushing teeth, drinking, etc). Children, seniors, and persons with weakened immune systems are particularly vulnerable to harmful bacteria, and all customers should follow these directions.


To ensure destruction of all harmful bacteria and other microbes, water for drinking, cooking, and ice making should be boiled and cooled prior to use for drinking water or human consumption purposes. The water should be brought to a vigorous rolling boil and then boiled for two minutes.

In lieu of boiling, individuals may purchase bottled water or obtain water from some other suitable source for drinking water or human consumption purposes.

When it is no longer necessary to boil the water, SAWS will notify customers that the water is safe for drinking water or human consumption purposes.

Once the boil water notice is no longer in effect, SAWS will issue a notice to customers that rescinds the boil water notice in a manner similar to this notice.

Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.
