Saint Lucia

Wastewater management remains a challenge in Saint Lucia, where only a small share of the population is connected to centralized sewerage systems, and most households depend on septic tanks or pit latrines. In coastal villages such as Canaries, untreated discharges flow into rivers and the sea, posing risks to both public health and ecosystems. Livestock operations also contribute to nutrient and organic waste loads, while weak regulation of small-scale facilities has limited options for enforcement. 

Through GEF CReW+, Saint Lucia advanced both national frameworks and pilot solutions. At the institutional level, the project supported the development of Wastewater Guidelines for On-Site and Small-Scale Treatment Facilities, providing technical standards to improve design, construction, and operation of decentralized systems. It also delivered an enhanced national IWWM database to consolidate data for internal monitoring and external reporting, strengthening evidence-based decision-making across agencies. 

At the community level, the program implemented low-technology and sustainable wastewater management solutions in Canaries, upgrading public facilities with rainwater harvesting, water-saving retrofits, and improved septic systems. Nature-based measures such as vetiver planting were added to reduce runoff into coastal waters. 

To address agricultural waste, CReW+ piloted a sustainable wastewater and manure management system for a piggery in Volet, Mon Repos, Micoud District, including a biodigester for energy recovery and nutrient recycling. This initiative demonstrated practical options for reducing pollution while creating co-benefits for farmers. 

Together, these activities strengthened the regulatory environment, improved data management, and introduced innovative, low-cost models that can be replicated to advance integrated wastewater management across Saint Lucia.
