SEWAGE SPILL WARNING SIGNS POSTED

                       

            The City Department of Environmental Services today posted contaminated water warning signs at several additional locations on Oahu, including Blaisdell Park, Keehi Lagoon and Wailupe, where spilled wastewater from yesterday’s heavy rains entered the ocean and bodies of water leading to it.

         In addition to flooding dozens of homes and businesses, yesterday’s deluge, coming after six weeks of rain, flooded or damaged several portions of Oahu’s wastewater system.  One spill is continuing:  Partially treated wastewater continues to overflow from already-saturated injection wells at the state-owned Waimanalo Wastewater Treatment Plant. Warning signs were posted along Bellows and Waimanalo beaches.

       Yesterday’s spills also included:

·             An estimated 10,000 gallons spilled at 1015 North School Street in Lanakila and flowed into a storm drain and Kapalama Canal.

·             An estimated 1,000 gallons overflowed from a manhole at 700 Umi Street in Kalihi, entering Kalihi Stream. Signs have been posted on Kalihi Stream bridges downstream and along  Keehi Lagoon.

·             An estimated 600 gallons of untreated wastewater spilled at 98-159 Olepe Loop in Waimalu, entering Pearl Harbor at Blaisdell Park. Warning signs were posted at the mouth of Waimalu Stream.

·             Roughly 4,000 gallons spilled in Wailupe when two manholes overflowed and a section of a third manhole collapsed. Warning signs have been posted along the shoreline.

·             An estimated 9,500 gallons of untreated wastewater spilled when Popoia Road near Kailua Beach Park was flooded.  Signs were already posted along Kaelepulu Stream and Kailua Beach because of several other spills upstream on Friday. Runoff from the extreme rains flooded the Enchanted Lake Pump Station and the Kailua Heights Pump Station on Friday afternoon, temporarily disabling them. In addition, runoff in the system led to spills from manholes on Hele Street, Wanaao Road and other spots in the Enchanted Lake area.

 

            Previously reported spills on Friday included:          

·             An estimated 1.8 million gallons of untreated wastewater spilled in the Ala Moana-Kakaako area when the Ala Moana Pump Station pumps stopped between 5:05 and 5:30 p.m. because of a power outage. The pumps were working at maximum capacity at the time because of the rains, and wastewater and infiltrated runoff backed up in sewer trunks feeding the pump station. About 6,900 gallons overflowed from manholes at Ala Moana Boulevard and Atkinson. Another overflow occurred at Cooke and Auahi streets. Warning signs were posted from Point Panic to Honolulu Harbor.

·             An estimated 10,000 gallons of untreated wastewater spilled between 1:35 and 4 p.m. from a manhole for the main that feeds the Kaneohe Pretreatment Facility and entered Kaua Stream, which empties into Kaneohe Bay.

·             An estimated 8,643 gallons of untreated wastewater spilled at the Aliamanu Pump Station No. 1 between noon and 3:21 p.m. because of runoff that infiltrated the system.

·             An estimated 8,132 gallons of untreated wastewater spilled from the Aliamanu Pump Station No. 2 between 12:08 and 7:16 p.m. because of runoff that infiltrated the system.

 

            The state Department of Health has been notified about all of the wastewater spills. Warning signs are being posted and water samples are being collected. The public is advised to avoid the affected waters. Those include Kailua Beach, Bellows Beach, Waimanalo Bay State Recreation Area, Ala Wai Canal and the waters from Honolulu Harbor to Fort DeRussy Beach.
