City of San Marcos issues boil water advisory

The City of San Marcos issued a boil water advisory for all water customers Wednesday. 

The city issued the advisory because of water pressure dropping within the distribution system. 

The city said the Texas Commission on Environmental Quality is requiring the city to issue a boil advisory with low water pressures being a result of power interruptions caused by the current winter weather. The advisory lasts until normal pressures resume and water quality lab results show no contamination.
