General information

Description of the project

The project aims to solve the problem of the failure of the existing cast-iron water supply system, which has completely exhausted its resource, has numerous bursts due to corrosion, and does not provide proper fire protection. The goal is to ensure a stable water supply for residents of Chornomorska and Shkilna streets in the village of Mayaki.

The purpose of the project

Main goal:

Improving the condition of infrastructure

Secondary goal:

Increasing compliance with modern standards, Increasing compliance with modern standards, Improving the equality of wealth distribution, Introducing innovations and energy-efficient solutions, Improving the quality of services, Reducing territorial or social gaps

Description of the purpose of the project and ways to achieve it

The main goal is to restore reliable and uninterrupted domestic and drinking water supply and ensure fire safety for residents of Chornomorska and Shkilna streets. The project involves the complete replacement of the emergency section of the network with a length of 1400.0 m, which is recognized as unsuitable for further operation, with a modern durable system. The following technical and organizational solutions will be used to implement the public investment project: Parallel route laying: The new network will be laid on a territory free from development parallel to the existing water supply without its prior dismantling, which will allow consumers not to be disconnected during the work. Use of modern materials: Replacement of old cast iron pipes with polyethylene pipes PE 80 SDR-17 with a diameter of 110x6.6 mm, which are resistant to corrosion and have an estimated service life of 50 years. Combined laying method: The main part of the pipeline is laid in an open trench at a depth of 1.3–1.6 m. At the intersections with the roadway, a trenchless method of pushing in steel casings (DN 325x8.0 mm) with reinforced insulation is used. Infrastructure modernization: Installation of 15 new reinforced concrete wells (diameter 1500 mm) with waterproofing and modern shut-off valves. Fire safety: Installation of 10 fire hydrants that will provide external fire extinguishing with a water flow of 10 l/s.

Problems and solutions resulting from project implementation

The key problem that the project aims to solve is the critical technical deterioration of a 1,400-meter section of the water supply network along Chornomorska and Shkilna streets, where the existing 100 mm cast iron pipes have rotted, causing frequent bursts and water leaks. The situation is complicated by the fact that the fittings in the wells are incomplete and damaged by rust, the walls of the wells on the inside are damaged or covered with debris, and the network is completely devoid of fire hydrants, which makes external fire extinguishing impossible. These problems are relevant now, since according to the conclusion of a technical inspection from 2023, the existing section was recognized as unsuitable for further operation and requires urgent major repairs. If these problems are not resolved, the consequences may be a complete cessation of water supply due to the destruction of pipes and the inability to ensure fire safety in the settlement. As a result of the project, it is expected to ensure reliable water supply through the laying of new polyethylene pipes with an estimated service life of 50 years, and the installation of 10 fire hydrants and 15 new reinforced concrete wells with modern fittings will guarantee fire safety and ease of operation of the network.
