Alamo Heights residents told to boil water

The city of Alamo Heights has issued a boil-water notice for its residents that will be in effect until at least 5 p.m. Saturday.

Patrick Sullivan, director of public works for the city, said that early Friday morning the pressure in the water system dropped below 20 pounds, and in accordance with the Texas Commission of Environmental Quality guidelines, a notice to boil water was issued.

Sullivan said the measure is precautionary and there have been no positive tests indicating the water is contaminated. But when the pressure drops, Sullivan said, there is potential for dirt, fertilizer or other contaminants to enter the water.

He said the results of Friday's tests will be available Saturday evening and he anticipates the boil water notice will be lifted at that time.
