More than 12,500 gallons of raw sewage spilled into Manoa Stream from a overflow on St. Louis Heights Drive.

It was reported at around 6 p.m. Tuesday at 1418 St. Louis Heights Drive.

Officials say asphalt and rocks clogged the pipe, pushing an estimated 30,030 gallons of raw wastewater out of the covered manhole and through the roadway.

A city Department of Environmental Services crew had to dig out and expose a paved-over manhole to release the blockage, which occurred at 10:30 a.m. Wednesday.

Approximately 12,530 gallons entered storm drains fronting 1406 and 1412 St. Louis Heights Drive, which empties into Manoa Stream. The crew was able to recover an estimated 17,500 gallons.

ENV notified the state Department of Health and is cleaning, disinfecting and deodorizing the affected area. Crews will also take water samples and post warning signs.

The public is advised to stay out of Manoa Stream until warning signs are removed.
