When the Waters Rise: Bali’s September Floods and the Urgent Work to Restore Its Rivers
In mid-September, heavy rains swept across Bali, causing some of the worst flooding the island has seen in years. One of the hardest-hit areas was Tukad Badung, where homes were destroyed, debris piled up, and plastic waste clogged the waterways. When rivers are blocked, the danger doesn’t stop at flooding, polluted water poses serious health risks to nearby communities.
As the floodwaters receded, the real challenge began: cleaning up what was left behind.
That’s where Sungai Watch stepped in.

Cleaning Up the Aftermath
Sungai Watch teams immediately mobilized across multiple sites, working around the clock to clear rivers of debris and restore the natural flow of water. In just two days, they removed 3,486 kg of non-organic waste. From plastic waste to personal belongings swept away by the flood.
Together with PUPR, DLHK, TNI, and the police, the cleanup extended to Pemecutan Kaja, Denpasar, where heavy organic waste was blocking the rivers. The joint effort made it possible to speed up recovery and reduce the risk of further flooding.
In some areas, like Tabanan, conditions were far more difficult. Teams had to navigate steep terrain and unstable riverbanks to safely remove debris and prevent future blockages.

Twelve Days, Nine Rivers, and Tons of Waste
From September 14–25, Sungai Watch’s emergency response teams worked across nine rivers that overflowed with trash after the floods. In 12 days, they removed over 12 tons of waste to help the water flow again and protect surrounding communities.
Even after the immediate response, their work continued. By the 25th day, Sungai Watch had removed an incredible 23.5 tons of waste from Bali’s rivers. A reminder of both the scale of the challenge and the importance of keeping waterways clean year-round.

Restoring Flow, Protecting the Future
Floods like these are a stark reminder that what happens upstream affects everyone downstream. Clean rivers mean safer homes, healthier communities, and a more resilient Bali.
At Topiku, we are proud to stand alongside Sungai Watch in their mission to protect and restore Indonesia’s rivers. Through every cleanup, they remind us that sustainability is not just about reducing waste, it’s about rebuilding what connects us all: nature, community, and flow.
