Access to safe water and adequate sanitation is a fundamental human right — and one that millions of people across the Pacific Islands do not fully enjoy. In some Pacific Island countries, less than 50% of rural populations have access to safely managed water. Sanitation coverage is even more limited. Climate change is making this worse — sea level rise is threatening freshwater lenses in low-lying atolls, and extreme weather events are damaging water infrastructure. Grant funding supports the WASH (Water, Sanitation, and Hygiene) programmes that bring safe water and decent sanitation to Pacific communities.
The Pacific WASH challenge
Water and sanitation is highly variable across Pacific countries:
- Fiji, Tonga, Samoa: better coverage, but significant rural-urban gaps
- Solomon Islands, Vanuatu, PNG: significant challenges particularly in rural and remote areas
- Kiribati, Tuvalu, Marshall Islands: freshwater scarcity, reliance on rainwater harvesting, climate vulnerability
- PNG: sanitation is particularly challenging — high open defecation rates in remote areas
Specific Pacific WASH challenges
Why WASH matters for Pacific health
Australian Government (DFAT)
Australia is the largest bilateral donor for Pacific WASH:
- Australian Water Partnership (AWP)
- Pacific Aid programme (WASH components)
- Humanitarian WASH response after disasters
New Zealand Government (MFAT)
NZ WASH funding in Pacific — significant in Tokelau, Niue, Samoa, and Cook Islands.
Asian Development Bank (ADB)
ADB funds major water infrastructure in Pacific countries.
World Bank
Pacific water and sanitation financing.
UNICEF
WASH in schools, emergency WASH, and WASH programming in some Pacific countries.
Pacific Community (SPC)
Technical assistance and coordination.
CARE Australia
WASH programmes in PNG and Pacific.
World Vision Australia
Community WASH programming.
Oxfam Australia/Pacific
WASH and humanitarian response.
The Rotary Foundation (WASH)
Rotary's significant WASH grant programme — particularly for water system construction.
Rural water supply
Urban water supply
Sanitation
Hygiene promotion
WASH in Schools
Climate-resilient WASH
Operation and maintenance
A persistent challenge — infrastructure is built but not maintained:
- Community water committee training
- Spare parts supply chains
- Tariff systems for O&M funding
- Technical maintenance training
Gender and WASH
Indigenous and traditional water knowledge
Traditional Pacific water management:
- Traditional rainwater harvesting
- Customary resource management
- Traditional knowledge integration with modern WASH
Pacific cyclones and disasters require rapid WASH response:
- Emergency water trucking
- Water purification (chlorination)
- Temporary toilet facilities
- Hygiene kit distribution
- Rapid water system repair
Climate resilience
Pacific WASH cannot ignore climate change — sea level rise and extreme weather are already threatening water systems. Applications that build climate resilience into WASH are essential.
O&M sustainability
The Pacific has a long history of WASH systems built but not maintained. Applications that invest in community capacity, governance, and supply chains for ongoing O&M are better positioned.
Gender
WASH has profound gender dimensions — women and girls bear the burden of water collection and suffer most from inadequate sanitation. Applications that centre women's participation and menstrual hygiene are more sophisticated.
Pacific ownership
Pacific-led design and community ownership is essential for WASH success. Applications with genuine community ownership, not external imposition, perform better.
WASH in schools
WASH in schools has excellent evidence — improving health, increasing attendance (particularly girls'), and establishing lifelong hygiene habits. Applications in this area have multiple beneficiaries.
Tahua's grants management platform supports Pacific development funders and WASH organisations — with programme beneficiary tracking, water access outcome measurement, humanitarian response data, and the reporting tools that help Pacific WASH funders demonstrate their investment in safe water and sanitation for Pacific communities.
