Viti Levu Master Plans, Water Authority of Fiji
Hunter H2O was engaged by Water Authority of Fiji to develop water supply and wastewater master plans to expand services in the main island of Viti Levu. The master plans focussed on systems in the towns of Korovou and Rakiraki, as well as unserviced areas between Sigatoka, Nadi, Ba and Tavua. The plans identified around FJ$250m of works to develop new systems to service existing populations and provide capacity for growth.
Potential water sources, treatment options and network servicing options were assessed to deliver potable water and provide a centralised wastewater network to existing and future developments in the areas. A multi-criteria analysis was undertaken to ensure that the proposed works provided the best balance of financial, social and environmental sustainability.
A regional assessment of options considered effective ways to share water between catchments. Opportunities to integrate water supply upgrades with power upgrades were developed during stakeholder consultation.
The schemes will improve access to water supply and sanitation to over 28,000 people by 2040.
