RegionsBlack Sea Region, Central Anatolia Region, Eastern Anatolia Region, Marmara Region, Mediterranean Region
Development need: Turkey’s performance on SDG 9 (Industry, Innovation and Infrastructure) exhibits major challenges, and significant challenges still remain for SDG 12 (Responsible Consumption and Production) according to the Sustainable Development Report 2020. (1)
Policy priority: The New Economy Program covering 2020-2022 emphasizes that projects on the “Zero Waste Initiative” will be extended. (2)
Gender inequalities and marginalization issues: Within the infrastructure sector, there is a high rate of informality among solid waste collectors. Workers in this area suffer from poor working conditions and a lack of social security. In terms of the provision of utilities, households with lower income levels face the risk of energy poverty. Fair employment practices and pricing mechanisms need to be implemented to address the issues of marginality within this sector. Investments in this area need to generate job opportunities within the green economy and promote energy-efficiency measures to decrease the household consumption costs.
Investment opportunities: The government has planned the following public investment amounts for urban infrastructure areas for 2020: 198 million TRY (29 million USD) for urbanization, 152 million TRY (22 million USD) for communication infrastructure, 71 million TRY (10 million USD) for environment and 67 million TRY (10 million USD) for municipal services. (3)
Key bottlenecks: Given high investment and operations costs, human capital and technology resources and governance needs, some urban infrastructure services such as wastewater treatment facilities cannot reach the desired efficiency levels. New models are needed to improve efficiency in urban infrastructure. (4)
Development need: Turkey is a water-stressed country. The annual per capita water supply is 1,365 cubic meters. Taking the negative impacts into consideration, this figure is projected to drop to 1,120 cbm in 2030. (5) Population access to wastewater treatment plants increased from 42% to 79% over 2005-16. (6)
Policy priority: The 11th Development Plan prioritizes provision of safe, clean drinking water and minimizing the negative effects of wastewater on population health. 11.7% of all wastewater was discharged as untreated in 2018. (7)
Gender inequalities and marginalization issues: There is a high rate of informality in the waste management sector of Turkey. Waste-pickers suffer from poor working conditions and a lack of social security. It is estimated that the informal recycling sector could be responsible for up to 30% of solid waste management. This is a key area of income for the urban poor and ethnic minorities. (20) (21)
Investment opportunities: Despite remarkable progress in wastewater management, 14% of residential wastewater is discharged without treatment. (6)
Key bottlenecks: Household water and wastewater tariffs exceed affordability limits in many provinces. Only a small number of Turkish water utilities have potential for tariff increase to finance new investments without harming the poorest households. (6)
Critical IOA Unit
1422 wastewater treatment facilities are planned to be built between 2017-2023. (8)
Approximately 27.6 billion TRY (4 billion USD) is allocated to wastewater and sewage investments by 2023. (8)
Based on interviews with active operators, returns from the construction of wastewater treatment facilities vary between 25-30%, while operating these facilities are associated with 10% losses. The overall return from investments in constructing and operating wastewater facilities is appr. 20%.
The planning, design and construction phases of a wastewater treatment facility is completed between 2-5 years. (9)
Turkey is a water-stressed country facing the risk of water scarcity in the near future. The annual per capita water supply is 1,365 cubic meters (cbm) in Turkey. Taking the negative impacts into consideration, this figure is projected to drop to 1,120 cbm in 2030. (10)
Population access to wastewater treatment plants increased from 42% to 79% over 2005-16. (11)
Despite remarkable progress in wastewater management, 14% of residential wastewater is discharged without treatment. (11) 11.7% of all wastewater was discharged as untreated in 2018. (12)
Industrial sites and mining zones discharge wastewater without treatment, which exposes communities living (particularly in rural areas whose livelihoods depend on wetlands) to health and economic risks.
Investments in this IOA can reduce the deterioration of surface water quality due to insufficient pollution control.
Investments in this IOA can reduce the deterioriation of surface water quality due to insufficient pollution control.
Investments in this IOA can improve watertreatment infrastructure to ensure that sewage and wastewater treatment services are provided at 100% by 2023. (8)
Wastewater treatment is especially important for rural communities whose livelihoods depend on the sustainability of wetlands.

There is a risk of overinvestment to reach stringent national effluent standards that go beyond EU standards for nutrient removal. (8)
As wastewater treatment technologies are foreign-dependent, expanding such facilities without improving local technology is likely to increase dependence on foreign technology. (11)
Impact RisksEfficiency Risk given the heavy involvement of local authorities in waste management
Endurance Risk given that the investment timeframes are heavily dependent on the duty terms of municipalities
Impact Classification
B—Benefit Stakeholders
Increased access to clean water and enhanced marine ecosystems.
People living in rural areas with limited access to wastewater treatment and sewage services will be served as well as life below water.
Involvement of municipalities in wastewater treatment facilities expose investments to uncertainty in terms of governance and leaves little governance capability for firms to maximize impact.
