Human waste is one of nature’s most versatile and abundant natural resources. Unfortunately, around 80% of the world’s wastewater is discharged into the environment, untreated. Wastewater pollution is harming our oceans. Its ripple effects jeopardize economic stability, food security, coastal resilience, and public and environmental health.

We are the Ocean Sewage Alliance and we have good news. Many solutions already exist to treat wastewater more effectively and to tap into waste's potential as a powerful resource. Let’s make them a reality.
