We are the Ocean
Sewage Alliance

The Ocean Sewage Alliance is a diverse collective of organizations and academic scientists committed to reducing the threat of sewage and other wastewater pollution in our oceans, while increasing the health and well-being of both humans and nature.

We aim to achieve our mission by collaborating across sectors, synthesizing and sharing knowledge, developing solutions, and raising awareness. 

Our Goals

Our OSA partners are engaged across five working groups focused on the following goals:


Building the case for action

Build an evidence-based case to drive action and support decision-making to reduce wastewater pollution

Breaking Silos Via Cross-Sector Collaboration

Catalyze and support cross-sector collaboration

Uniting Our Voice For Diverse, Global Representation

Be a united voice that encourages and supports action

Creating a Knowledge Hub For Learning & Sharing

Serve as a knowledge and learning hub to support the successful implementation of solutions

Funding Action For Real, Enduring Change

Expand our donor network and funding to both support the Ocean Sewage Alliance and drive funds towards action

Who Are We?

How We Began

Marine conservationists have spent decades working hard to protect our oceans. But recent studies have revealed a problem that could be making all these efforts futile: ocean wastewater pollution. No one has been talking about this well-hidden phenomenon, mostly because society has long believed that the ocean could naturally manage human waste. In reality, the ocean has been suffering unseen consequences.

Since late 2019, a growing group of organizations have been gathering to create a collaborative space to tackle the threat of ocean wastewater pollution once and for all. Together, we call ourselves the Ocean Sewage Alliance, which officially launched on World Oceans Day in 2021.
