4,000 Litres at a Time: Water Bombers Over Tangerang's Burning Landfill

The fire at Tempat Pemrosesan Akhir (TPA) Jatiwaringin — the final disposal site serving Tangerang Regency in Banten province — began at 12:30 local time on Tuesday, June 30, 2026. By the following evening it had defeated ten fire engines, produced two new hotspots on the site's northern flank, and pushed a column of thick smoke over the surrounding villages of Mauk subdistrict. As of the evening of July 1, Indonesia's National Disaster Management Agency (BNPB) reported the fire was still not under control and "still has the potential to spread."

A Fire the Ground Crews Cannot Reach

The numbers describe a fight fought at a disadvantage. TPA Jatiwaringin covers 33 hectares; initial field assessments on Wednesday morning put the burned area at roughly 15 hectares, a figure later refined to around seven hectares confirmed burned as data collection continued. Either way, the fire's seat sits at the top of elevated waste mounds that fire engines cannot approach and hose streams cannot reach. The material feeding it — mixed municipal waste, much of it plastic and organic matter — ignites easily, holds heat, and reburns. Strong winds and hot, dry weather have pushed flames in multiple directions at once. Ten fire engines from various agencies have been confined to knocking down fire along the edges of the site, in the areas vehicles can actually access.

This is the characteristic shape of a landfill fire, and it is why they are among the most stubborn fires any responder faces. Waste piles burn from within: combustion works its way deep into compacted layers, fed by pockets of methane generated by decomposing waste, and can smoulder for days or weeks after surface flames are extinguished. Water poured on the surface often never reaches the seat of the fire at all.

4,000 Litres at a Time

Faced with a fire that ground crews could contain but not extinguish, BNPB chief Lieutenant General Suharyanto ordered an air operation. "Get it extinguished as quickly as possible," he instructed his emergency response teams, ordering two water-bombing helicopters to the scene — and, if required, cloud-seeding operations to induce rain over the site. The first aircraft, a Mil Mi-8AMT with a 4,000-litre water bucket, was repositioned to Tangerang on July 1 from Jambi province, where it had been supporting forest and land fire operations. It flew its first sortie over Jatiwaringin on Wednesday afternoon. A second helicopter completed mobilisation the same day, and both were scheduled to fly from Pondok Cabe airbase on Thursday, July 2, focusing on wetting and cooling hotspots unreachable from the ground.

The redeployment itself tells a story about Indonesia's stretched aerial firefighting assets: the helicopter now flying over a landfill fire near Jakarta was, days earlier, part of the national karhutla (forest and land fire) operation in Sumatra — the same fleet, moved from one fire emergency to another as priorities shift.

Displaced by Smoke, Not Flame

No homes have burned. Yet around fifty residents have moved into the Tanjakan Mekar village hall, displaced by smoke dense enough to make staying home unsafe. The local government has distributed 46 mattresses and placed a health team on 24-hour standby for respiratory complaints; masks have been distributed in surrounding settlements. BNPB has advised residents to limit outdoor activity, and to keep infants, the elderly, and people with respiratory conditions away from smoke exposure. Burning mixed waste releases fine particulate matter along with a chemistry set of combustion products from plastics — which is why smoke from a waste fire is treated as a more serious health hazard than smoke of equivalent density from a vegetation fire.

The Tangerang Regency government declared a fire disaster emergency status on July 1 — Regent's Decree No. 609 of 2026, in force through July 14 — activating a command post structure to coordinate agencies. One geographic detail drew early attention: the landfill sits roughly 12 kilometres from the western end of Soekarno-Hatta International Airport's runway. As of July 1, flight operations remained normal and unaffected.

The Waste Mountain Problem

Jatiwaringin is not an anomaly. Indonesia's landfills have produced some of the country's deadliest and longest-running non-natural disasters. In February 2005, a waste avalanche at the Leuwigajah dump in West Java buried two villages and killed more than 140 people — a catastrophe that led Indonesia to designate a National Waste Awareness Day and, on paper, to phase out open dumping. In 2023, a fire at the Sarimukti landfill serving the Bandung region burned for weeks, forced a waste-collection crisis across four cities, and was ultimately handled as a provincial disaster emergency. Overloaded sites, methane accumulation, dry-season heat, and informal burning practices make fires close to inevitable; what varies is whether the response machinery around them is ready. At Jatiwaringin, the emergency declaration, the command post activation, and the air support arrived within 48 hours of ignition — fast by historical standards, though the fire itself will decide how long the operation lasts.
