City crews cleaned a sewage spill on N. School Street Tuesday.
Officials say heavy rain overwhelmed a 36-inch pipe, sending 32,925 gallons of raw wastewater out a manhole.
The Department of Environmental Services was notified at 3:17 a.m., arrived on scene at 3:43 a.m., and stopped the discharge at 6 a.m.
Crews were able to recover 1,200 gallons with cesspool and Vactor trucks, but approximately 31,725 gallons went into a storm drain that empties into Kapalama Stream and eventually Honolulu Harbor.
Crews cleaned, disinfected, and deodorized the area. Water samples were taken, and warning signs have been posted.
As a reminder, ENV asks residents not to drain rain water into the sewer system by opening clean outs and manholes, and to refrain from draining rain gutters into the system as it is not designed to accommodate excess rain water.
