Barbados

 General Information

Barbados has achieved near universal access to safe sanitation, with 99% of its population covered. Yet, only about 6% of properties are connected to central sewage systems, and most households rely on septic tanks, soakaways, or pit latrines. While these systems have helped safeguard public health, they contribute to nutrient-rich discharges that threaten fragile coastal ecosystems, including coral reefs. Elevated nitrogen and phosphorus levels from wastewater and fertilizer use have been linked to reef degradation, highlighting the urgent need to strengthen integrated water and wastewater management (IWWM).

The country has put in place zoning regulations and a National Water Reuse Policy, but challenges remain in enforcing standards, financing modern systems, and raising public awareness. Maintenance of decentralized systems is inconsistent, and the high cost of nutrient-removing technologies often discourages developers and communities. With climate change expected to intensify water scarcity, securing reliable and safe reuse options is vital.

Through GEF CReW+, Barbados developed a National Communications Strategy and Implementation Plan to raise awareness on water reuse and the importance of IWWM, and created the enabling environment for sustainable financing mechanisms, including the groundwork for a wastewater revolving fund. These actions established the policy, financial, and knowledge frameworks needed to scale innovative, low-cost wastewater solutions and promote water reuse. In doing so, the project strengthened Barbados’ efforts to protect its aquifers, safeguard its marine environment, and build resilience.
