The San Antonio Water System issued a boil water notice for the City of Somerset on Monday.
On Monday afternoon, a crew drilling broke through a water main and gas line south of Loop 1604 on Somerset Road, said SAWS.
SAWS advises customers to boil all water that will be used for drinking and cooking.
The boil water notice is expected to remain in place through Tuesday.
Bottled water is available at Somerset City Hall, and K Street and Somerset Road. A dispensing station is also available to refill clean customer containers at 19260 Somerset Road.
