A major water pipeline ruptured last night in San Bruno, spilling millions of gallons of water and remaining open into this morning NBC Bay Area reports. According to the San Francisco Public Utilities commission, regional water utilities are seeking backup supply plans.

The break, the Daily Journal reports, occurred in Junipero Serra County Park at the entry to the park on Crystal Springs Road. No property damage has been reported as the water is flowing back through the park and into a creek that runs to the Bay.

The pipeline is part of the Hetch Hetchy Water System and supplies the peninsula. And SFPUC spokesperson called the loss "easily millions of gallons."
