The water sector – contributing to the implementation of Grenada’s NDCs

Like all small island states in the Caribbean region, Grenada faces the risk of water scarcity, exacerbated by climate change, and has high potential for the introduction of renewable energy and energy efficiency. The government has identified the resilience of the water sector as a priority in all national climate strategy documents and successfully submitted a large-scale project to the Green Climate Fund (GCF), which in its compontents 1-3 aims to improve the resilience of the water sector. The components 4 and 5 of this GCF project are co-funded through this IKI Project, which is developing the first carbon-neutral water utility in the Caribbean and disseminating this approach in the region. In this context, it is advising the Grenada National Water and Sanitation Authority to improve its water and energy efficiency. To this end, it promotes the introduction of renewable energy and supports the implementation of the water loss reduction strategy.

State of implementation/results

In August 2023, a national greenhouse gas report for the water sector was produced for the first time in Grenada.
The National Adaptation Plan (NAP) completed its consultations in June 2025 and is awaiting official approval by the Cabinet. Between 2023 and 2025, a total of 30 consultations were held with a total of 200 participants. The NAP continues to prioritise the water sector as a high adaptation priority, based on lessons learned from the project, including the enforcement of rainwater harvesting laws and improved water resource management and governance.
Sectoral consultations on the National Climate Policy, led by the National Climate Change Committee, were completed in July 2025. The National Climate Policy was discussed between February and July in 12 consultative meetings with over 100 stakeholders. The climate consultations also serve to raise public awareness of climate resilience and enable the government and the project to engage in direct dialogue with communities.

In March 2023, negotiations began with the Grenadian regulatory authority and the electricity utility on the CO2 reduction strategy of the National Water Authority (NAWASA). The project advises NAWASA on its CO2 neutrality strategy.
In August 2024, plans for three solar photovoltaic systems were drawn up at the NAWASA water authority as part of climate proofing measures, and in 2025 a tendering and procurement process for the solar photovoltaic systems at three locations was successfully completed.

Due to the great success in water loss control through improved data management and water balancing, NAWASA established a dedicated ‘non-revenue water’ department within the company, which has been operational since September 2024. Since the new department was established, numerous water metering areas have been equipped with new measuring devices. In addition, leaks have been repaired.

The Regional Exchange Platform “Regional Climate and Water Resource Community” has 75 members (including observers) from across the Caribbean region. Depending on the topic of discussion, associate members are also invited to the meetings, thereby expanding knowledge exchange and participation.
The G-CREWS project presents 2-3 case studies from the project annually at the Caribbean Water and Wastewater Association conference.
The G-CREWS Water Ambassadors Program (GWAP) received significant recognition at the 13th Conference on Comprehensive Disaster Management in Nevis.
In March 2025, G-CREWS, in collaboration with Minister of Climate Resilience, Renewable Energy, and Environment, Hon. Kerryne James, organised a forum on water technologies as part of the regional Nationally Determined Contributions Finance Initiative (NDCFI) conference.
The project organised a study tour for participants from the region who are currently working on project proposals for climate-resilient water projects to be financed by the Green Climate Fund (GCF). Participants from Saint Kitts and Nevis, Saint Lucia, Grenada, and the Organisation of Eastern Caribbean States (OECS) exchanged ideas on infrastructure, project management, and public relations strategies.

In February 2024, the project organised a webinar on non-revenue water, during which Jamaica and Grenada presented their approaches and learning experiences in water loss control.
A delegation from the national water authority visited the IFAT trade fair in May 2024. The mission of the NAWASA team was to develop and propose technical solutions to existing challenges in the water sector in Grenada.
In February 2025, the project team organised a webinar on “Gender-Responsive Water Resilience: Integrating Gender into Project Design and Implementation.”
The project supported the Government of Grenada in launching the first knowledge management portal and clearing house for climate resilience in Grenada.
G-CREWS works closely with the Global Water Partnership-Caribbean (GWP-C). G-CREWS collaborated with GWP-C to conduct a training on Integrated Water Resources Management (IWRM), which not only strengthened regional technical capacity but also served as a platform to attract new members to the community. During this training, the G-CREWS project presented the lessons learned from the passage of the Water Resources Management and Regulation Bill, 2025, to approximately 47 participants from across the Caribbean region.
