The dredging works – delivered by Hall Contracting on behalf of the Ministry of Agriculture and Waterways – have increased the river’s water discharge capacity, enabling it to release high volumes of water into the South Pacific Ocean more efficiently during heavy rain and storm events.
Minister for Agriculture and Waterways Honourable Vatimi Rayalu said the project exemplifies government's evidence-based approach to disaster risk reduction and serves as a cornerstone of the National Flood Management Strategy.
“It aligns with our commitments under the Sendai Framework and Sustainable Development Goals, demonstrating how proactive infrastructure investment delivers exponential returns through disaster prevention,” said Hon. Rayalu.
The Ba River catchment has endured devastating floods for generations. Major flood events in 1931, 1956, 1975, 1983, 1993, 2004, 2009, 2012, 2019, and 2020 have repeatedly devastated communities, with the 2009 floods alone claiming 11 lives and affecting over 100,000 people.
“Progressive siltation at the river mouth has reduced discharge capacity, transforming normal rainfall into catastrophic floods.”
Hon. Rayalu added that the project delivers multi-dimensional benefits.
“Restored natural hydraulic efficiency significantly reduces flood frequency and severity for Ba Town and surrounding communities. There is also increased protection of agricultural lands, businesses, and infrastructure, ensuring continuity of livelihoods and reducing disaster response costs.”
“There will be improved river health, water quality, and restored navigational access for fishing communities as well as enhanced safety, reduced health risks, and restored confidence for long-term settlement and investment,” added Hon. Rayalu.
Hall Contracting CEO & Director Cameron Hall said the dredging and marine infrastructure company had removed more than 300,000m3 of silt, sand and gravel from a 3.6km stretch of waterway extending offshore from the mouth of the Ba River.
“Our cutter suction dredge, Kikilu, commenced working on the project in August 2024, and dredged to a depth of around three metres below mean sea level throughout the nine-month period of works,” Mr. Hall said.
“While further dredging campaigns will be required to maintain the improved discharge capacity and address natural sediment build-up in the river over time, these works will greatly mitigate flood risk for homes, businesses and agricultural land now and in the future.”
Mr. Hall said the project had generated employment for four Fijian workers, with team members receiving training in dredge and workboat operations.
“Having undertaken several maintenance dredging campaigns in Fiji in recent years, we’re proud to offer employment and training opportunities to local workers and to play a role in safeguarding communities against the effects of severe storm and rain events,” he said.
The Ba River flood mitigation works were completed in May 2025.
