Millions of gallons of sewer water spills in Windward Oahu from storm

Posted: Updated:

Last weekend's rainstorm caused nearly nine-million gallons of sewer water to spill on the Windward side of Oahu.

6.5 million came from the Kaneohe Pretreatment Facility, but five other places leaked as well, including both Popoia and Kawailoa Road in Kailua.

Peter Holst, a Kailua resident of over 30 years, said his street off of Kawailoa Road was flooded with waste water over the weekend.

 "It was coming over from the golf course, and out of the manhole covers, and neighbors had started up a couple good sized pumps but it doesn't keep up with it." Described Holst.

He said he’s noticed sewage coming up more often within recent years.

"This was an unprecedented amount of rain. It was about 160% of what we normally see.  It was the second wettest February in history since 1991. That flow is somehow getting into our system and I'm not quite sure how to stop it." Explained Director of Environmental Services Lori Kahikina.

The city admits it cant prevent sewer spills, but is trying to minimize them.

"We've rehabilitated sewer lines where there's maybe some leaks. So, we've rehabilitated miles and miles of sewer lines per the consent decree. Somehow the rainwater is still coming in." said Kahikina.

The city is also draining all rain and waste water collected in the pretreatment facilities to make room for any new rainfall that might occur. 

Homeowners can also do their part by not intentionally draining their storm water into sewer systems.

"Their rain gutter is intentionally connected to the sewers, it's not supposed to be. Explained Kahikina, So they need to disconnect that and just let it drain into their yard and into the storm drain because it's two completely separate systems. Storm drain systems and sewer systems."

Brown water advisories have been issued for Kailua beaches, Oahus North shore, Kaneohe Bay, Kapoho, Maui, and Kauai. They could stay up if the rain hits hard here again.
