Alhambra residents in the south side of the city beginning Tuesday will likely see workers from contractor National Plant Services — and smoke — trying to identify leaks within the city’s sewer system.
The smoke is used to pinpoint breaks and defects in the system, Alhambra Vice Mayor Jeffrey Maloney said.
“The sewer system’s really important that it’s just the sort of waste that the system is set up to handle, and if other things get in there, whether that’s potable water or other materials or dirt or debris, it has a chance to really break down the system,” Maloney said, “that can cause much bigger issues, obviously.
“So they really want to make sure that the system itself isn’t compromised, make sure that it serves the needs of our community.”
Maloney said the main thing is making sure storm water doesn’t infiltrate the system. He said when that happens, “It can overwhelm the sewer quickly and lead to sewer failure and spills.”
Testing will be conducted between the hours of 8 a.m. and 4:30 p.m. and should be completed within 12 to 15 days, according to a news release distributed by the city of Alhambra.
