19.7299° N, 155.0907° W
Quick Overview
Hilo's got several RV dump station on record, and it's free -- that's some out of some, so you're not paying to dump here. The sani-dump is at the Wastewater Treatment Plant, a straightforward municipal facility that gets the job done without frills.
Hilo sits on the Big Island's rainy windward side, where the RV scene is quieter than Kona but still active with snowbirds and inter-island travelers who ferry their rigs over. Most RVers here are either exploring Volcanoes National Park or working their way around the island's eastern coast. The dump station situation reflects the city's practical, no-nonsense vibe -- you won't find a bunch of commercial RV resorts with fancy sanitary dump stations, but you will find what you need.
The Wastewater Treatment Plant is your go-to for RV waste disposal in Hilo proper. It's a municipal setup, which means it's reliable and maintained by the county. Access is decent for most rigs, though you'll want to confirm hours before rolling up -- municipal facilities sometimes have specific dumping windows.
Getting to Hilo means either Highway 19 from the north (Hamakua Coast) or Highway 11 from the south (Volcano side). Both routes are RV-friendly, though the 19 has more dramatic coastal views and occasional one-lane bridge sections. Check the full station listing below for exact directions and any recent user notes about the facility.

Traveling to Hilo by RV
Highway 19 and Highway 11 are your main arteries into Hilo. The 19 hugs the coast from Waimea and has some narrow sections with one-lane bridges -- they're manageable in an RV, but you'll need to yield and take it slow. Highway 11 comes up from Volcano and is wider, with better sightlines for bigger rigs. There's no interstate here; this is Hawaii.
RV routing around Hilo itself is straightforward. Downtown streets can be tight, but the main commercial strips along Kanoelehua Avenue handle RVs fine. Watch for low-hanging banyan tree branches in older neighborhoods. Overnight parking is tricky -- Walmart policies vary, and the county doesn't love RVs posted up at beach parks overnight. Your best bet is a proper campground or RV park if you're staying more than a night. Rain is constant on this side of the island, so plan for wet roads year-round, especially in winter.

Dump Station Costs in Hilo
Of the several stations here, some (a portion%) are free, while a portion% charge a fee -- so you're in luck. The Wastewater Treatment Plant doesn't charge RVers to dump, which is typical for municipal facilities in Hawaii. If you venture to other parts of the Big Island, paid dump stations at private RV parks usually run $10 to $20 for non-guests.
Hawaii's overall cost of living is high, but dump station fees aren't the main expense you'll face. Fuel, groceries, and campground rates will hit your wallet harder. Since Hilo's dump is free, take advantage of it and don't skip dumping just to save a few bucks elsewhere -- black tank issues in Hawaii's heat are miserable. If you're island-hopping with your RV (yes, people ferry them), factor in those costs; the inter-island barge isn't cheap. No special passes or memberships apply here, just show up and dump.

Explore the Hilo Area
Hit the dump station early in the day if you can -- municipal facilities sometimes close by mid-afternoon, and you don't want to show up at 4 PM only to find the gate locked. Bring your own hose and gloves; this isn't a full-service setup. Water fill-up is available at some county parks, but confirm it's potable before topping your fresh tank.
Propane can be found at U-Haul on Kanoelehua Avenue or Lex Brodie's -- call ahead to confirm they're filling that day. Diesel and gas are pricier here than the mainland, so fuel up strategically. If you need RV repairs, options are limited; most folks head to Kona for serious work. The Hilo Farmers Market on Wednesdays and Saturdays is RV-accessible if you arrive early, and it's worth the stop for local produce. One more thing: the Wastewater Treatment Plant dump station doesn't have a rinse hose at the site, so plan accordingly.
