The City of Castroville Boil Water Notice 

Boil Water Notice

We are issuing a boil water notice for Castroville residents due to a major water main break today. The water remains off while we repair the break. When the water is back on, you will need to bring your water to a vigorous rolling boil and then continue to boil for an additional two minutes. Boil water prior to consumption (e.g., washing hands/face, brushing teeth, drinking, cooking, etc.). The Boil Water Notice will be in effect pending results of water sample testing indicating our water is safe for consumption. If you have any questions, please call Public Works at 830-931-4090.

Temporary Boil Water Notice


This has been one of the most challenging winter storm events in Castroville's history. Castroville Public Works employees have worked tirelessly to provide and maintain water service.
As we struggle with low pressure and frozen pipes within homes, we believe that it is in the best interest of our customers to issue a "Temporary Boil Water Notice." This cautionary measure is warranted until the region thaws. The 100 plus hours of below-freezing temperatures have caused users to have issues maintaining-above 20 PSI in portions of the distribution system. At this time, please take precautions to boil your water until you are notified by City of Castroville Public Work that you do not have to.
We apologize for the inconvenience but rest assured we are working around the clock to resolve the issues and restore full service to all our customers.
