Strengthening water security in Tuvalu

The ‘Strengthening water security in Tuvalu’ project will expand previous water security interventions to establish effective backup water supply and access for households, schools, government facilities and the wider communities of Funafuti. A number of technical training opportunities will be provided in areas of desalination operations and maintenance, water management and maintenance of water harvesting systems to the PWD staff, local technicians, teachers and students of Fetuvalu High School, Seventh Day Adventist (SDA) Primary and pre-schools in Funafuti.

Project Focus: Water Sector

Direct benefit: 6,716 persons
Indirect benefit: 3,929 persons

  • Geographic coordinates: Lat. 5° – 11°S, Long. 176°- 180°E
  • Total land area 26 km²
  • Exclusive economic zone (EEZ) 757,000 km²
  • Population (2019 estimate) 11,646
    • Temperatures have warmed and will continue to warm with more very hot days in the future. 
    • Rainfall shows no clear trend since 1927. Projections of annual rainfall are unclear, with models indicating little change. Wet and dry years will still occur as a result of natural variability. Extreme rainfall events are projected to become more frequent and more intense. Drought frequency is projected to decrease by the end of the century.
    • Ocean acidification has been increasing in Tuvalu’s waters. It will continue to increase and threaten coral reef ecosystems.
    • Sea level near Tuvalu has risen and will continue to rise throughout this century. 
    • December to March wave heights and periods are projected to decrease slightly

How does this project address climate change adaptation in Tuvalu?

Water scarcity is a major issue in Tuvalu with the issue intensifying severely in dry seasons and droughts. This situation is exacerbated as a result of climate change and variability.  The primary water source is from rainwater catchment systems and groundwater is classified non-potable in most islands due to high salinity levels and pollution. In Funafuti, the demand for freshwater is close to reaching the estimated sustainable yields for freshwater supply. Improving water security is a high priority for the Government of Tuvalu and the SUPA project will scale up and support the ongoing efforts by the Government of Tuvalu.

The project will scale up past initiatives by the Government of Tuvalu and Japan on the backup supply of freshwater through desalination plants. A 20m³/day, solar powered and portable desalination unit will be procured and installed in Funafuti to supply the residents with freshwater. Enhanced skills in operations and maintenance of the unit will be achieved through specialized training of PWD staff and relevant technicians in the country. In times of dry spells and when needed, the unit may be transported to and used in outer islands. 

To improve water supply and access, a water truck of 10,000 litre capacity will be procured and operated in Funafuti by the PWD.  The truck will deliver freshwater from the desalination plants and water cisterns to the residents of the island.

After assessments of the water systems at Fetuvalu High School and the SDA Primary schools in Funafuti, the water systems will be refurbished. Training on water management and water systems maintenance will be provided to the staff and students of the two schools.
