Boil water notice issued for the entire City of Houston after water pressure dropped due to power outage; City of Bellaire has since rescinded order

Estimated 2.2 million people impacted

HOUSTON – The entire city of Houston remains under a boil water notice, city officials announced Monday night.

The notice was issued Sunday night after the pressure from the city’s main water system dropped below the Texas Commission on Environmental Quality’s required minimum of 20 PSI during a power outage at the East Water Purification Plant on Nov. 27 at 10:30 a.m., according to Houston Public Works.

Late Sunday, the mayor’s office tweeted that the order may not be lifted until late Monday night or Tuesday morning.

On Monday, Texas Commission on Environmental Quality approved the Houston Public Works water sampling plan. Officials said workers will begin collecting samples Monday morning and will do two complete sets to send to the lab for processing.

Out of an abundance of caution, the city of Bellaire also issued a water boil notice late Sunday night. It was later lifted at around 7 p.m. Monday.

Additionally, Houston Independent School District canceled all operations for Monday and Tuesday due to this issue.
