Description of the project
The project involves the construction of solar power plants at stations I and II of the Sambirsk VUVKG lift in order to increase the reliability and continuity of the water supply and drainage systems of the city of Sambora. The implementation of the project is aimed at solving critical problems of energy dependence of water utility facilities, which are among the most energy-intensive in the municipal infrastructure and significantly depend on the stability of the power supply. Frequent fluctuations in electricity prices, risks of accidents in the power system and potential outages create a threat of interruption of water supply and operation of pumping equipment, which directly affects the life of the community and sanitary and epidemiological safety.
The project plans to install modern photovoltaic modules with a total capacity sufficient to partially cover the annual electricity needs of stations I and II of the lift, which together consume a significant amount of electricity. This will provide backup power to critical equipment, reduce electricity costs, and increase the resilience of the water and sewerage infrastructure. The solar plants will operate in parallel with existing networks, creating an additional level of energy security in case of crisis situations. The expected results include increasing the energy independence of the water utility, reducing operating costs, reducing CO₂ emissions through the use of renewable energy, and improving the quality and stability of water supply services for community residents. The implementation of the project will contribute to achieving sustainable development goals and increase the resilience of municipal infrastructure to external risks in the long term.
The purpose of the project
Main goal:
Introducing innovations and energy-efficient solutions
Secondary goal:
Contribution to climate or environmental goals, Increasing compliance with modern standards, Creation of new facilities and services, Improving the condition of infrastructure, Improving the quality of services
Description of the purpose of the project and ways to achieve it
The project's goal is to ensure stable and uninterrupted operation of the water supply and drainage systems of the Sambirsk Waterworks by implementing a non-volatile and climate-sustainable source of electricity supply - solar power plants at stations I and II of the lift, which will reduce the enterprise's energy consumption and reduce CO₂ emissions.
Methods of achievement:
* construction of two new engineering structures - solar power plants at stations 1 and 2 of the lift;
* installation of modern photovoltaic modules, inverters and operation monitoring systems;
* integration of the solar power plant into the waterworks' power supply system with the possibility of further increasing capacity;
* optimization of energy consumption and installation of equipment resistant to voltage fluctuations;
* introduction of innovative solutions for backup power supply of critical infrastructure;
* use of renewable energy to reduce the enterprise's operating costs.
Sambirsk VUVKG is completely dependent on unstable power supply from the grid; frequent fluctuations and emergency shutdowns lead to the shutdown of pumping units; high electricity costs (1452 MWh per year); lack of backup power sources; critical infrastructure is vulnerable during accidents or peak loads.
Availability of its own renewable energy source capable of providing a significant share of the needs of pumping stations; stable operation of water supply and wastewater systems; reduction of the burden on the water utility budget; increased resilience to emergencies; reduction of CO₂ emissions; fulfillment of community obligations under the Covenant of Mayors.
Problems and solutions resulting from project implementation
The water supply and drainage systems of the Sambirsk Water Utility operate in conditions of high energy dependence, which creates significant risks for the stability of their functioning. Pumping stations of the 1st and 2nd rise consume significant amounts of electricity, and the increase in tariffs, frequent power outages and the threat of emergency shutdowns directly affect the continuity of water supply to the population and critical infrastructure facilities. An additional factor is the wear and tear of electrical equipment and the lack of backup power sources, which increases the likelihood of downtime and reduces the reliability of services.
The relevance of the problem is exacerbated in conditions of climate change, when rising temperatures and extreme weather events increase the load on water management systems, as well as in conditions of martial law, when the stability of water supply is critically important for the safety of the population. If the problem is not resolved, an increase in the frequency of failures and interruptions in water supply, an increase in the financial costs of the water utility, a deterioration in the quality of services and a decrease in the community's resilience to crisis situations are possible.
The implementation of the project will reduce the water utility's dependence on external electricity supply, reduce energy costs, increase energy security, ensure uninterrupted operation of key water management facilities, and contribute to the community's climate goals by reducing CO₂ emissions. This will ensure reliable water supply for the population, businesses, and social infrastructure, increasing the overall sustainability and efficiency of the system.

Results of the feasibility analysis
Economic Analysis
Social benefits and costs
The implementation of the project will ensure increased reliability of water supply and drainage for community residents, which directly affects the quality of life and sanitary and hygienic safety of the population. Thanks to the stable operation of the water utility, the risks of water supply interruptions are reduced, especially during accidents or peak loads on the energy system. An additional benefit is increased resilience of critical infrastructure in emergency situations and possible attacks on energy facilities. There are no or minimal social costs, since the project does not require changes in tariffs or additional payments by the population. The implementation of the project also contributes to the positive image of the community as one that implements modern sustainable solutions.
Environmental benefits and costs
The installation of solar power plants will reduce CO₂ emissions, as a share of the electricity for the water utility will be generated from a renewable source, which reduces the burden on the environment. The project will contribute to improving the quality of atmospheric air by reducing the use of energy produced from fossil fuels. In addition, reducing energy consumption from the network will reduce the risk of man-made load on the energy system of the region. Environmental costs are minimal and are associated only with the production and disposal of equipment, but these processes are regulated by international standards and have limited negative impact. Overall, the environmental effect of the project is positive and significantly outweighs possible minor impacts.
Indirect benefits and costs
The implementation of the project will contribute to increasing the investment attractiveness of the community, as it will demonstrate its orientation towards modern and energy-efficient technologies. Reducing dependence on fluctuations in electricity prices will improve the financial stability of the utility and reduce the risks of unforeseen costs in the future. The installation of solar power plants creates opportunities for the development of local expertise in the field of renewable energy and the formation of new partnerships. At the same time, indirect costs are possible due to the need for periodic training of personnel to work with new equipment and potential delays due to weather or technical factors.
