Waimanalo Gulch Landfill & Ash Monofill

Waimanalo Gulch Landfill & Ash Monofill sits out on Farrington Highway in Kapolei and handles the island’s heavier disposal needs. Neighbors, local contractors and haulers all use it when trash needs to be buried or ash needs to go to a monofill. It feels like an industrial site more than a tidy drop-off, so come prepared.

Drive up to a gate/scale area where loads are weighed - tipping fees are charged by weight, so expect to stop to be weighed in and again on the way out. The property is large with heavy equipment and trucks moving around; follow the traffic flow and any cones or signs. After weighing you’ll be directed to a dumping pad or ash area depending on the load, then head back across the scale to finish. Landfills of this size commonly accept commercial loads, though exact rules and fee schedules are set by state and local agencies.
