WAIPAHU, OAHU (HawaiiNewsNow) - The City's Department of Environmental Services responded Monday morning to a sanitary sewer overflow in Waipahu.
The call came in just after 8:40 a.m. A crew arrived before 9 a.m. and secured the site.
Grease clogged a 10-inch pipe on Awamoi Street, discharging an estimated 3,500 gallons of untreated wastewater from a manhole into Waikele Stream, which leads to Pearl Harbor West Loch.
City crews notified the state Department of Health. They cleaned, disinfected and deodorized the affected area near the overflow. Warning signs are posted and water sampling is underway. The public is advised to stay out of the affected waterways until warning signs have been taken down.
