About This Location

WM - Waimanalo Gulch Sanitary Landfill is Oahu's primary municipal landfill, operated by Waste Management at 92-460 Farrington Highway in the Kapolei area on the island's leeward (west) side. It is a permitted sanitary landfill that accepts municipal solid waste, ash, non-friable asbestos, contaminated soil and other special waste under disposal (tipping) fees. This is a commercial disposal facility rather than a household recycling or HI-5 container-redemption center; residents looking to redeem beverage containers or recycle should use a certified redemption or drop-off center instead.
