Construction debris today caused 2,700 gallons of untreated wastewater to spill into a storm drain that empties into Palolo Stream, city officials said.

A manhole overflowed fronting 2128 Palolo Ave., caused by a line clogged with debris comprised of construction materials. The discharge was reported at 11:04 a.m. and had stopped flowing at 2:09 p.m. An estimated 2,700 gallons entered the stream from a storm drain located several hundred feet away.
Water samples will be taken and warning signs have been posted along Palolo Stream from 2128 Palolo Ave. to the canoe launch near McCully Street Bridge.
The public is advised to stay out of Palolo Stream and the Ala Wai canal until signs have been removed.
Crews from the city’s Department of Environmental Services sucked up and redistributed approximately 4,000 gallons of untreated wastewater to a downstream manhole for treatment at Sand Island Wastewater Treatment Plant.
City officials said a construction company resurfacing Palolo Avenue last week paved over all of the manholes and city crews had to break through the pavement to get to the manhole.
