1 Grenada s collaboration with the CTCN Improvement of water supply management through GIS-based monitoring and control system for water loss reduction Technology matchmaking in small island states Fiji Pavilion, Bonn, 9 th November 2017 Mr. Trevor Thompson, Ministry of Agriculture, Lands, Forestry, Fisheries and the Environment GRENADA

3 Watershed Management Units on Mainland Grenada and Carriacou: (Source: Land Use Division, Ministry of Agriculture) Grenada has 71 Watersheds, Carriacou has 20 Watersheds, Petit Martinique has 1. On Grenada the watersheds are characterized by a relatively dense network of permanent rivers, while the sister islands are dominated by intermittent streams.

4 WATER RESOURCES 34 water supply systems for water production Capacity: Rainy Season 14 mgd Dry Season 9 mgd Surface water sources are approx. 85% Ground Water sources are approx. 15%

5 EXISTING LEGISLATIVE AND POLICY FRAMEWORKS National Water Policy The water sector has a huge impact on social and economic development and has been identified as a key sector in: Climate Change Adaptation Plan TNA National Climate Change Policy NDC

6 Water as a Climate Change Priority National Climate Change Policy outcome to reduce [ ] water outage times during flooding and droughts, increased domestic and corporate usage of water conservation/efficiency measures, and reduced incidence of uncompliant surface, sub-surface and coastal water quality. Nationally Determined Contribution A resilient water sector is crucial to the long term development of Grenada as a nation and that improved capture, storage, distribution and conservation of water increases the adaptive capacity of individuals and communities National Adaptation Plan water sector being one of Grenada s most vulnerable sectors and re-confirmed the water sector as a policy priority

7 Justification For Proposal Old pipe network Contributed To NAWASA S Unaccounted for Water Estimated at 25-35%

8 Needs identified in the Study The 4 basic work processes identified are: 1. GIS implementation and customer management 2. Improved NRW calculation and water balancing 3. Repair and preventive maintenance, focused rehabilitation 4. Water consumption metering Two additional modules to improve the economic viability are: Improved energy efficiency in water production and distribution Electricity generation

9 Recommendations 2016 study Upgrade of NAWASA s Water Leak Detection Equipment Training of staff Comprehensive Institutional Restructuring Using Geographical Information System Good industrial standard Information backbone on customer, pipelines,etc for the management of Non-Revenue -Water, Structure management processes to support the information and data flow between the different divisions.

10 Proposal Requested Grenada requested the CTCN to: Source the equipment Provide technical assistance to conduct the implementation Establish a GIS-based monitoring and control system Improve management processes for water loss reduction and leakage detection in Grenada with NAWASA.

11 CTCN Approved The technical assistance will focus on: Setup of a GIS data model Development of schematic drawings of water supply networks Establishment of a pilot District Metered Area (DMA) Development and implementation of a concept and program for electricity generation using in-conduit turbines within NAWASA s piped network system

12 GIS data impact on Grenada s water sector Better understanding of the reasons for the losses Faster response times for providing solutions in case of leakage, Support for preventive maintenance and exchange of pipelines Reduce NAWASA s NRW from an estimated level of 30-35% to 20%. Reduce water risks deriving from lack of storage Reduction on operation & maintenance cost of water infrastructure Improved water access for communities Reduced electricity expenses through self generation
