In the North region of Fiji, several key water supply sources have hit critical levels due to an ongoing drought and prolonged dry spell. The Water Authority of Fiji (WAF) reported a significant decrease in rainfall over recent months, severely impacting water availability across various supply systems.
Despite these challenges, WAF has been diligent in monitoring water sources and managing operations to sustain service continuity wherever possible. In Savusavu, water levels have remained stable, with critical flows upheld at Moliwawa, Savuloaloa, and Naidriva. This stability is vital for the water treatment plant’s steady production. However, in Labasa, the main water source at Nasealevu has seen a 50% decrease in flow, raising concerns about water sustainability in the area. Currently, this source is augmented by the Navau pump station, delivering a consistent flow of 12.58 million litres per day, while the Sarava raw water source continues to perform healthily.
Conversely, the Vunika system, which serves the outskirts of Labasa Town, is under significant pressure as its two gravity-fed sources have been impacted by the ongoing drought. WAF noted that these sources, consisting of spring and gravity-fed catchments, have seen a drastic reduction in flow, making it challenging to meet regular supply needs, especially in elevated areas. To address this shortfall, WAF has deployed six water carting trucks to the Vunika area to ensure residents have access to water.
The situation is compounded by the Taganikula scheme nearing critical levels, with supply interruptions primarily due to unplanned outages. While the Seaqaqa water supply system continues to deliver reliable service from the borehole near the Natua River, the Nabouwalu system in Bua is facing difficulties due to a 60% decrease in inflow. WAF is taking proactive steps through continuous valve operations to minimize disruptions.
On Taveuni Island, sources at Somosomo, Waiyevo, and Bucalevu have benefitted from intermittent rainfall, maintaining healthy levels. However, the Mua scheme, which supplies Matei, Naselesele, and Wiwi, is currently experiencing critically low flows and relies on water carting and night-time valve management to meet demand.
As the dry spell persists, WAF emphasizes the importance of conserving water and urges communities in affected areas to be mindful of their usage. The authority remains hopeful that persistent monitoring and management strategies will mitigate supply challenges, ensuring that residents have access to essential water resources during these difficult conditions.
