Objective and Purpose of the Assignment

Fiji is a small island developing state in the South Pacific, spanning a land area of 18,300 square kilometers and consisting of over 300 islands, of which 110 are inhabited. Viti Levu and Vanua Levu, the largest islands, are home to about 97% of the 900,000 population. The high urbanization rate in Fiji's Western District, which includes towns like Sigatoka, Lautoka, Ba, and Rakiraki, is part of the broader national trend of increasing urbanization. Fiji's overall urban population grew from 50.7% in 2007 to 55.9% by 2017. The Western District, especially areas like Nadi-Lautoka, has seen a higher rate of urbanization compared to other regions due to its economic importance, growing infrastructure, and migration from rural areas. The urban population increase has been driven by factors like natural population growth and rural-urban migration. This urbanization is marked by an increase in informal settlements, which poses significant challenges to solid waste management. Informal settlements, lacking proper sanitation and waste services, contribute to environmental degradation and health risks.

The towns in the Western District are facing increasing pressure to improve waste management infrastructure and environmental monitoring as urbanization continues, with plans to enhance landfill operations and relocate dumpsites where necessary. In this context, the Ministry of Local Government (MLG) wishes to explore the feasibility of developing new landfill sites and rehabilitating four existing dump sites as a public-private partnership (PPP) project under the terms of the national PPP Policy. The MLG has limited capacity to develop and implement such a project and has requested assistance from the Asian Development Bank’s (ADB) Office of Market Development and Public Private Partnerships as an experienced transaction advisor. The Transaction Advisory Services Agreement (TASA) will be executed with the MLG, which is responsible for developing and implementing urban development strategies.The project involves the development and operation of a new sanitary landfill and the remediation of four existing open dumpsites in the Western District of Fiji, covering Sigatoka, Lautoka, Ba, and Rakiraki. The project will be jointly implemented by the Government of Fiji’s Ministry of Local Government (MLG) and the Ministry of Environment and Climate Change (MECC). A suitable public- private partnership structure will be developed to mobilize private sector expertise, ensuring the most efficient and effective development and implementation of the project.As part of the transaction advisory services, ADB intends to engage a consulting firm to conduct the following technical surveys in relation to the remediation of the four existing open dumpsites: (a) geotechnical and groundwater surveys and investigations; and (b) drone-based topographic surveys and waste depth investigations.The geotechnical and groundwater surveys and investigations aim to support the safe remediation of existing dumpsites by understanding both the subsurface soil conditions and the status of groundwater in and around the dumpsites. The purposes of the geotechnical investigation components are to determine the subsurface soil conditions, relative soil characteristics and texture, consistency, and classification. The focus is on the geologic and subsurface soil conditions and subsoil parameters that will help determine the location and design of any in-situ remediation at the dumpsite (e.g., consolidation, compaction, and capping of waste, which requires a location that is high above peak groundwater levels and a geology that minimizes pathways from the surface to underlying groundwater). Furthermore, the investigation is to identify any suitable materials that can be utilized in the capping layers.The purpose of the geo-hydrological investigations is to determine the peak groundwater levels, which will help to determine the location and design of in-situ remediation.The purpose of the groundwater quality investigations is to determine the state of groundwater quality, establishing a baseline prior to the site's remediation. This will help inform the success of subsequent remediation in reducing the polluting-producing aspects of unmanaged waste.For each dumpsite, drone-based topographic surveys and waste depth investigations are needed to generate site-specific data to support the development of remediation strategies and designs. This will include determining the lateral extent, depth, and volume of waste at each site. The data will help assess the scale of in-situ remediation options, define areas suitable for capping, and evaluate the potential feasibility and economics of waste relocation to new landfill facilities.
