Sacramento firefighters were dispatched to the pump house on the American River after two people got trapped inside after scaling several fences to access the five-story building, which is connected to the Fairbairn Water Treatment Plant in the 7500 block of College Town Dr. near the Sacramento State campus.

The woman apparently fell into a suction pool inside the pump house and the man couldn’t get her out. He was identified Wednesday as Eric Zane Sleeman, 21. Sleeman was already out of jail Wednesday morning after being arrested for trespassing.

The woman, whose name wasn’t available, was taken to UC Davis Medical Center after suffering from hypothermia. A warrant request for trespassing was submitted for the woman’s arrest, according to police. She was not identified.

Someone on the levee nearby reported hearing screams coming from inside the pump house and called 911 shortly after 8 p.m.

According to fire officials, the two appeared to be intoxicated. They didn’t say how the two were able to get inside the pump house.

The water treatment plant has had several security upgrades since the Sept. 11, 2001 terrorist attacks to better protect it from possible contamination threats.

Firefighters said they walked in through an unlocked gate, but city officials won’t say how the got inside and they won’t comment on security at the facility.
