and we have good news

Human waste is one of nature’s most versatile and abundant natural resources. But unfortunately, the majority of it ends up in our oceans. In fact, around 80% of the world’s wastewater is discharged into the environment, untreated.

Wastewater pollution is harming our oceans, with impacts felt across both developed and developing nations. Its ripple effects jeopardize economic stability, food security, coastal resilience, and public and environmental health. But there’s actually good news. There are many solutions already in place to treat wastewater more effectively and to tap into waste's potential as a powerful resource—both of which can improve a whole host of global issues. The solutions already exist; let’s make them a reality.

How can you help?

There are many ways you can get involved and reduce the impacts of wastewater pollution. It all starts with educating yourself about how waste is managed in your own home and community.

  • Refrain from flushing pharmaceuticals or personal hygiene products down the toilet.
  • Regularly maintain your home’s stormwater gutter system, as well as any on-site septic systems, if you have one.
  • Start breaking the taboo by talking about the issue with your friends and family.
  • Reach out to your local representatives through community meetings, petitions, and letters.
  • When voting, support government policies that fund infrastructural improvements in water management.
  • Donate to programs that are
    implementing safe sanitation solutions.
  • Donate to the Ocean Sewage Alliance

He and his team piloted the Cinderella Incineration Toilet, an innovative toilet alternative that burns waste to eliminate bathroom blackwater. They’re now combining it with greywater and blackwater systems to create a cesspool replacement.
