Wastewater pollution is a major threat to Caribbean waters, communities and economies. Poorly treated wastewater affects marine life, damages coral reefs and poses serious health risks. TNC in the Caribbean has launched a regional Wastewater Awareness Campaign to drive action and highlight solutions in three key countries—Jamaica, the Dominican Republic and Grenada— where studies revealed both the challenges and opportunities of wastewater management.

At a virtual event themed “Protect Our Water, Protect Our Future,” TNC launched the awareness campaign. The event brought together environmental leaders, scientists and artists, including Aria St. Louis, head of the Environment Division of Grenada’s Ministry of Climate Resilience, the Environment and Renewable Energy, and featured a special performance by Jamaican performer and environmental educator Jean Brown.

The centerpiece of this initiative is public engagement and education. To support this, TNC unveiled a new animated video, “Wata Flow,”, designed to raise awareness about wastewater pollution and inspire action. The campaign will also include ongoing educational outreach to diverse audiences, capacity-building and collaboration with local partners to improve wastewater management across the region.

These countries’ communities see wastewater pollution as a shared responsibility that requires action from governments, businesses and individuals. The studies’ findings also point to nature- based solutions, such as constructed wetlands, as effective ways to convert wastewater management into a natural benefit for the environment and its inhabitants.

By combining conservation and public awareness, the awareness campaign aims to protect water sources, strengthen coastal resilience and ensure a healthier future for Caribbean communities and marine ecosystems.
