More than 80% of plastic pollution in the ocean comes from rivers and streams.

We believe one of the simplest ways to clean our ocean is by starting in our rivers, where we can still prevent the flow of plastics.

The Solution — Install Simple Trash Barriers

Plastic is now polluting every river in the world.

We believe that every free running river (big or small) should have some type of barrier. Our barriers are the perfect tool to get communities and governments involved in cleaning our waterways. Through these barriers, we are able to better understand what is polluting our rivers and how we can improve our actions on land.

Over the past year we have been testing, designing and deploying more than 100 barriers using the island of Bali as our test lab. We have tested different types of technologies from booms, nets, cages to blocks and we are now developing a 100% recycled trash barrier made from the rivers of Bali.

We are now on a mission to place trash barriers in every river in Indonesia by 2025 and eventually the world.

Cleaning Rivers

· We install multiple barriers per river to better understand flaws in waste management

· We organize emergency cleanups at illegal TPAs and along riverbanks to prevent plastic from entering rivers

· We host mass education and socialization campaigns with the local community to prevent throw-away behavior

Our workflow:

  • 1

    Daily cleanups of every barrier

  • 2

    Sort every piece of trash we collect into categories

  • 3

    Analyze and record data to fuel converstations around plastic pollution with stakeholders

  • 4

    Wash, shred and prepare trash for recycling

  • 5

    Every waste category we collect has value - we are currently experimenting with ways to turn trash into products


What a year 2021 was!

In 14 months since setting up our first barrier, we have installed 105 barriers around Bali and we have diverted more than 333,000 kgs from Bali's rivers. We are so thrilled to be sharing our first Impact Report, which dives into our first year of work. Through this report you will learn how our barriers operate, the full operation behind up-cycling river plastics into valuable commodity and find an in depth analysis of the trash we collect. This is really just the beginning for us and we cannot wait to bring Sungai Watch to other parts of Indonesia and the world!

We are grateful to be working with more than 50 Sungai warriors who go out every day to clean our rivers on behalf of Sungai Watch.

We are big believers that in order to see real changes in our rivers, we need to work with local communities by empowering local heroes at every cleanup.

Here is how you can help us place more barriers!
