SMEC International Pty Ltd, the managing contractor for Indonesia Infrastructure Initiative (IndII) assigned DHV B.V. on 30 November 2010 to undertake a scoping study on solid waste management in Indonesia.

The solid waste management sector in Indonesia basically consists of a collection of domestic and commercial solid waste, transfer and transportation of waste, and final disposal. A 2008 JICA study revealed that an estimated 58 percent of the total Indonesian population receives public waste collection services. Although this coverage is relatively low, the operating arrangements for solid waste management go back a long time and are well embedded in village and regional structures. The legal framework for solid waste management, prepared by the Ministry of Environment, has been set out in the Waste Management Law no. 18/2008, and defines three types of waste: household waste; household like waste; and specific waste. The Waste Law also includes criminal provisions for failure to comply with waste management regulations, and provides a one year grace period for planning the closure of non‐complying disposal sites and a five year grace period for the actual closure of non‐complying disposal sites.


The Indonesia Infrastructure Initiative (IndII) has appointed EnviroSolutions & Consulting Pte Ltd (ESC) in association with Vista Consulting Engineers Limited (Vista) to prepare the Detailed Engineering Design (DED) for the Regional Solid Waste Disposal Site (RSWDS) Mamminasata, South Sulawesi Province, Indonesia.  The detailed scope of work and programmme for the DED was set out in the study's Inception Report (Revision 1) (March 2010).  

This report represents the amended Final Design Report for the study and presents the final versions of each of the design and study components/tasks, and includes final drawings, descriptive text, bill of quantitiies (BoQ) and specifications for: the landfill, leachate treatment plant (LTP), sorting and composting plant and supporting facilities. The final tender documents, recommendations for the feasibility of a plastics recycling plant and the final access road study, as well as the final version of the training materials are also included.

The final designs have been developed with a view to maximising efficiency, minimising capital and operating costs whilst ensuring environmental provisions are adequate to meet design criteria. ESC seek endorsement of the designs presented to enable completion of this project.
