• Reconstruction of backwash water re-use and sludge dewatering facilities on the water treatment
facilities
• Construction of a hypochlorite production facility at the water treatment facilities

As a result of the project, more than 25 000 new customers were connected to the new centralized
sewage system. The construction of new sewers led to the connection of new residential districts
and commercial properties.

Sustainable Development Goals impacts

SDG 3: Improvement of health and well-being of residents resulting from the cleaner water supply.

SDG 6: Guaranteed clean water source and improved sanitation through treatment, distribution
and management facilities.

SDG 9: Innovative technologies to improve water sanitation and hygiene while reducing electricity
consumption.

People-first elements

• Improved living conditions: The project resulted in a reduction of water-related diseases. It also
involved local manufacturers and used the best available technologies. Residents now have
greater access to the water supply from 20 to 24 hours; water quality was also improved, with
98 per cent meeting sanitary norms.
• Reduced environmental impact: Electricity consumption was reduced by more than 25 per cent
per cubic meters of wastewater. The full treatment of sludge was dedicated to recultivation of
soils and for use in agriculture. Implementing UV-disinfection for wastewater means that no
chlorine is entering the River Don.
• Greater access for vulnerable populations: The project improved access to modern sanitation
infrastructure for low-income populations. Elimination of the infrastructure gap through
connection to a centralized wastewater network has led to the development of new restaurants,
cafes, business centres and residential houses.

Financial information

The project was financed with a mix of equity, debt and capital grant finance of CapEx in the local
currency. It also consisted of four financing blocks:

1 Expenses related to reconstruction and modernization of the water supply systems in Rostov-
on-Don

2 Expenses related to repairs and development of sanitation systems
