In December 2017 on the Ocean Campus, an outdoor water leak broke out on the southwest edge of the Multi-Use Building (MUB). What began as a bubbling puddle developed into large areas of standing water that flowed into the MUB parking lot and into a nearby sewer drain for nearly two months until it was repaired on Feb. 16.
It’s unclear how much water was lost. The college suspected that a leaking fire hydrant caused the leak, so the San Francisco Fire Department investigated and ruled this out.
Before the college could begin digging, it contacted PG&E and AT&T to ensure that it would not damage utility lines servicing MUB.
The college’s sole plumber had difficulty finding the source of the leak, so the college hired a contractor specializing in water leak detection.
Using sophisticated tools, the contractor pinpointed the source of the leak to a portion of the main water supply line servicing the MUB.
