Gallons and gallons of water are freely flowing on some streets on the South side of San Antonio -- on purpose.
San Antonio Water System opened up certain fire hydrants to flush the system on Wednesday.
A lot of water comes from Medina Lake and former water utility BexarMet.
The water has been cleaned with chloramines because SAWS fears that due to the warm temperatures, the quality of that water is less than they desire.
"It's perfectly safe. It is perfectly within regulatory requirements but it's going in a direction we are not happy with," said Anne Hayden, SAWS spokeswoman.
SAWS is opening up some 350 hydrants across South San Antonio, Bexar County and even into Atascosa County for approximately 10 minutes each. They are using a three-chlorine system to get the water up their standards
Residents can expect so see some cloudy water and even smell chlorine over the next few days.
"But, once again, it is perfectly safe to drink," Hayden said.
The project will take until Friday.
Hayden said residents are welcome to use the water to cool off, or take some buckets and get some for plants or grass.
SAWS officials had many discussions about the timing of the project, since it is the heat of the summer, and whether letting water run down the street would be a great example.
"Once again, it came back to the conclusion that water quality is No. 1. We want to make sure that all of our customers are safe," Hayden said.
