Boil water notice: Here's what you need to know

Mayor Sylvester Turner advises all City of Houston residents to continue boiling their water through at least Saturday morning.

HOUSTON — UPDATE: The boil water notice that had been in effect has been lifted.  Here's what you'll need to do before using water now.

_____________________________

All Houston residents are advised to boil their water because of Thursday's water main break.

The boil water notice will continue until at least 7 a.m. Saturday, Mayor Sylvester Turner said Friday.

The mayor said TCEQ approved water samples at 8 a.m. Friday but protocol requires them to check again after 18 hours. Turner said they'll make a decision on whether to lift the notice Saturday morning. 

Even though it's an inconvenience, the health department warns you shouldn't take a chance before then because there could be bacteria in the water.

"You can get toilet water coming into the main lines," said Dr. David Persse, the physician director for the City of Houston. 

The 96-inch line that burst provides 50 percent of the city's water.
