Unprecedented infrastructure investment program set to underpin Indonesian socio-economic development

In 2021, SMEC and JV partners CDM Smith were appointed by GIZ to prepare 18 Urban Infrastructure prefeasibility studies across the provinces of West Java, Central Java, East Java and Bali. The studies will investigate viable solutions to improve Urban Water and Wastewater Management, Urban Solid Waste Management and Urban Public Transport. The aim of the studies is to enable the government at national and sub-national level (provinces, districts, cities) to identify suitable infrastructure investment opportunities under the Indonesian-German Green Infrastructure Initiative.


CDM is the overall project lead, with SMEC Denka Indonesia providing national experts in water and wastewater, solid waste management and urban public transport. As the local consultant SMEC has led stakeholder liaison and day to day coordination of activities.


SMEC’s scope includes social, environmental, and economic analysis as well as detailed investigation into local institutional conditions and technical surveys to analyse site conditions. Key deliverables included data gap analysis, sector assessment, stakeholder engagement, timeline projections and associated work plans to inform the business case for each project.


As part of the project SMEC is coordinating with key stakeholders including the Government of Indonesia, Ministry for Maritime Affairs and Investment, Ministry of Public Work and Housing, Ministry of National Development Planning, Ministry of Transportation, KfW and Local Government representatives.

Water and Wastewater Management

World Bank data records that a large proportion of Indonesia’s wastewater flows into agricultural fields, rivers, and open channels, having hugely negative impacts on the environment and communities.

According to the “Global Carbon Atlas”, Indonesia ranks 10th in the list of the largest emitters of greenhouse gases (GHG). Of the total of approx. 5 tons of CO2 emissions per capita, a large part is attributable to urban areas (transport, waste, water/wastewater, energy). SMEC proposing a comprehensive configuration of wastewater treatment plant and fecal sludge management that taking into account greenhouse gas emission reduction and environmental protection, as well as to promote gender equality.

Integrated Citarum Domestic Wastewater Management, Southern West Java

The aim of this study is to provide pathways to improved sanitation for infrastructure communities in the Citarum River Basin to handle domestic wastewater. The team recommended two investment packages and looked at ways to increase community participation in the local domestic wastewater treatment infrastructure management process. It is estimated that the two recommended investment packages could provide access to improved wastewater management services to 220,261 households in Bandung City, Bandung Regency, and Cimahi City.


Solid Waste Management

Most of the solid waste generated by Indonesians annually is sent to open landfills, which has a negative impact on the health of the environment and local communities.

As known before, solid waste is one of the environmental sector that contributed to the greenhouse gas emission. One of the objectives of this project is aiming to improve solid waste management by choosing the best environmental friendly technology to treat the waste and minimize the release of methane gas, a generated from decomposing organic waste in landfills, to the atmosphere. Women may be more exposed to health risks from waste collection and disposal, and they may have limited access to waste management services. Therefore, gender mainstreaming can help to ensure that waste management policies and practices are inclusive and equitable.

Regional Landfill Sarbagita, Bali

In 2022, SMEC delivered a concept design for a new regional landfill in in Denpasar, Bali. The site, known locally as Sarbagita Suwung, will be closed and renaturalised with methane capture and leachate treatment technology. An integrated and comprehensive technological approach is proposed. In landfill, it is imperative to improve sustainable landfill management and the application of modern waste processing technology.

Kediri Waste Management, East Java

Emissions from existing waste disposal facilities, causes large quantities of greenhouse gas emissions and has a negative effect on the health of residents. The Green Infrastructure Initiative has identified an opportunity to develop a new waste treatment plant in Kediri, East Java which would allow around 300 tons/day of waste to be treated.

The new waste management system would improve waste collection, treatment, recycling, and disposal in a modern fully equipped facility.  One of the proposed treatments being explored is the use of Black Solider Flies which can help reduce the weight of organic waste by 50% before it is transported to landfill.


Urban Public Transport

Although over 50% of Indonesia’s National Strategic Projects are dedicated to transport infrastructure only around a quarter fall into the green infrastructure category. The Urban Public Transport program seeks to elevate environmentally conscious transport outcomes. Urban public transportation plays a significant role in mitigating climate change by reducing greenhouse gas emissions from private vehicles. Efficient public transport systems can encourage people to switch from personal vehicles to public transport, thereby reducing traffic congestion, air pollution, and carbon emissions. Ensuring that the needs and preferences of women and men are considered in this project is, since women often experiencing greater barriers to accessing public transport due to safety concerns, caregiving responsibilities, and other factors. By incorporating a gender perspective into public transport planning, it is possible to make public transport systems more accessible and safe for women, which can in turn help promote gender equality.

The team endorsed the development of a Sustainable Urban Mobility Plan and associated studies, to inform the business case for a future Bus Rapid Transport network.  SMEC has provided feasibility planning for the Greater Surabaya BRT, which identifies two possible investment corridors for new BRT systems.  As part of the feasibility planning SMEC undertook costs estimates for infrastructure such as roads, pavements, stations, ticketing systems a systems control centre and monitoring costs.
