Waste Management - Waimanalo Gulch Sanitary Landfill

Large county landfill out near Kapolei that handles the island’s buried refuse; mostly used by contractors, commercial haulers and residents dropping off big loads. It’s the place to go when trash won’t fit in the curbside bin and commercial loads need a final destination on Oʻahu.

A weigh scale and an entrance booth are part of the drive-in procedure, so plan to stop twice for the in/out weight ticket. The site is big - rolling mounds of compacted trash and dirt roads, with traffic lanes for dump trucks and smaller vehicles. There’s usually a line on weekends and during neighborhood cleanup events, and different materials are kept apart so people don’t just dump mixed loads. Vehicles pull up to a tipping area where drivers unload and then head back across the scale to finish the transaction.
