The objective of the project is to improve the reliability and resilience of the centralized water supply system of the Chornomorsk Territorial Community through the construction of a new Ø800 mm transmission water pipeline from the Velyky Dalnyk connection point to checkpoint PK130, with a total length of 12.2 km. Currently, the community’s water supply largely depends on a single main transmission pipeline, which is in unsatisfactory technical condition. In the event of аварії or pressure drops along certain sections of the pipeline, there is a risk of a complete interruption of water supply to the population. In addition, hydraulic losses and terrain-related constraints periodically affect the ability of the system to maintain the required pressure levels. The project objective will be achieved through the construction of a new backup pipeline branch, which will ensure stable delivery of drinking water, reduce the risk of emergency interruptions, increase the reliability of the water supply system, and create infrastructure capacity for the future development of the community.

The key problem addressed by the project is the low reliability of the main water supply system serving the Chornomorsk Territorial Community. Currently, the supply of drinking water largely depends on a single operational transmission pipeline, which is in unsatisfactory technical condition, while system redundancy is practically absent. A significant portion of the second pipeline line, constructed from cast iron and steel pipes between 1961 and 2013, has reached the end of its service life and can no longer ensure stable system operation. In the event of a failure or shutdown of the main pipeline, there is a risk of a complete interruption of centralized water supply to the population, social infrastructure facilities, and local businesses. An additional challenge is related to hydraulic losses and complex elevation conditions along certain sections of the pipeline, which periodically lead to pressure drops and restrictions in water supply. If these problems remain unresolved, the likelihood of network failures, service interruptions, and deterioration of water security for the community will increase. The implementation of the project will create a new backup transmission pipeline, increase the reliability and resilience of the water supply system, ensure stable delivery of drinking water to community residents, reduce the risk of emergency interruptions, and provide the necessary infrastructure foundation for the future development of the centralized water supply system.
