illages (koro) and settlements in rural and coastal

areas of Fiji are gaining increased access to piped

household water supplies and adopting the use of

flush toilets. Inadequate systems for managing the resultant

wastewater flows are a frequent cause of localized contami-

nation and pollution of streams and rivers used for water

supply, bathing, laundry and recreation, and nearby lagoons

and beaches. Thus, apparent improvements in water supply

and toilet facilities are unwittingly leading to increased health

risks. The WASH Koro project is developing and demon-

strating a range of sustainable community water supply and

on-site wastewater treatment solutions for Fijian villages that

protect public health and reduce contaminant loadings to

surface and coastal waters. Social, scientific and engineering

approaches have been integrated with local and indigenous

knowledge, resources and construction techniques to engage

the local community and build capacity at village level.

Water and sanitation in Fiji

Fiji is an archipelago of 332 tropical islands in the South

Pacific, about 1,770km north of New Zealand. It has a popu-

lation approaching 0.9m, of which about 85% live on the two

main islands. Heavy rains (up to 3m or more annually) fall

on the windward southeastern side of these mountainous

islands, while the leeward north and western sides experi-

ences annual rainfall of about 1.7m with distinct wet and

dry seasons. This means that, except for seasonal periods of

drought, the main islands are comparatively well endowed

with freshwater resources.

About 46% of the Fijian population lives in rural villages

and settlements, with indigenous iTaukei (predominantly

Melanesian with a Polynesian admixture) comprising about

57% of the population. Traditional villages or koro are

commonly sited near the coast or along inland rivers and

streams. Tourist resorts along the coast provide jobs and

income to supplement livelihoods based largely around agri-

culture, fishing and forestry.

According to WHO/UNICEF Joint Monitoring Programme

(JMP) statistics for 2015, approximately 91% of the rural

population of Fiji has an improved drinking water source

and about 88% has access to improved sanitation facili-

ties. This makes Fiji one of the few small island developing

states (SIDS) in Oceania to have apparently achieved the

Millennium Development Goals, placing it well ahead of

other small island nations in Oceania, which report that,

collectively, only 56% and 34% have access to improved

water and sanitation facilities, respectively.

However, work over the last ten years in Fijian villages

along the Coral Coast of Viti Levu, one of the more devel-

oped rural areas of the largest island, suggests that the

WHO/UNICEF JMP estimates for rural areas are optimistic

compared to on-the-ground reality. In particular, they fail

to identify significant quantity and quality aspects of water

supply and sanitation infrastructure and associated manage-

ment, and the extent of associated water-related health and

pollution issues.

Rural water supplies are most commonly from surface-

water sources which are often compromised by catchment

disturbances including cropping, farmed and feral animals,

and forest harvest. Both continuity of service and quality of

these water sources are vulnerable to impacts from heavy

rainstorms and episodic cyclones or hurricanes, exacer-

bated by climate changes. Little or no treatment of such

waters usually occurs. Some villages have access to wells

or bores, and supplementary roof water harvesting has also

been promoted in recent years. Overall, the capacity of water

supplies to deliver water to villages is gradually increasing

across the country, with many villages transitioning from

communal standpipes to individually piped supplies to

households. This commonly leads to installation of flush

toilets and showers, and use of washing machines, creating

a significant wastewater flow that needs management.

Lack of adequate wastewater management facilities, beyond

small capacity septic tanks for blackwater, results in rapid

clogging of soakage pits, particularly in the heavy clay soils

common beyond the narrow coastal fringe of coral sands.

This can lead to significant localized contamination and

pollution of streams, rivers, lagoons and beaches used for

bathing, laundry and recreation by villagers and tourists. Such

wastewater impacts are exacerbated by leaking taps and toilet

cisterns, poor septic tank construction practices and a general

lack of maintenance, with most septic tanks operating while
