Description of the project
The project is aimed at comprehensive restoration (reconstruction) of filtration fields and replacement of worn-out centralized wastewater networks in the city of Sambir, Lviv region, in order to improve the ecological state of the environment, increase the efficiency of the wastewater treatment system and ensure the sustainable functioning of the community's water and sewerage infrastructure. The filtration fields, which have been in use for over 60 years, are in unsatisfactory technical condition: partially destroyed dams, silted-up maps, damaged drainage pipes and worn-out wastewater networks. This reduces the efficiency of wastewater treatment, increases the risk of soil and surface water contamination, in particular the Dniester River, which creates environmental and sanitary and epidemiological risks for the population.
The implementation of the project involves: * conducting engineering and geodetic surveys of the filtration field area; * reconstruction of existing filtration maps with strengthening dams and installing a modern drainage system; * replacing emergency sections of centralized wastewater networks; * installing a sludge removal system and its further disposal; * introducing energy-efficient equipment for technological processes; * landscaping the surrounding area taking into account environmental requirements. The project is being implemented in accordance with current state building codes and standards in the field of environmental protection and water management.
Expected implementation results: * reduction in the volume of untreated or partially treated wastewater entering natural water bodies;* increase in the level of environmental safety and sanitary condition of the community territory;* reduction in emissions of pollutants into the environment;* stable operation of the wastewater system even with increased load due to population growth and IDPs;* improvement in the quality of municipal services and improvement of living conditions for community residents.

Description of the purpose of the project and ways to achieve it
The project aims to improve the efficiency of the centralized wastewater system in the city of Sambor by reconstructing filtration fields and replacing emergency networks, which will ensure high-quality wastewater treatment, reduce environmental pollution and improve the ecological safety of the community. The project is aimed at achieving the climate and environmental goals of the community in accordance with the Covenant of Mayors and the local plan for sustainable energy and climate development.
The project includes: conducting engineering and hydrogeological surveys to clarify the condition of the filtration fields; developing and implementing design and estimate documentation for the reconstruction of filtration maps and drainage systems; replacing worn-out pipelines and collectors of centralized wastewater networks; arranging sediment collection systems, their transportation and disposal in accordance with environmental requirements; introducing energy-efficient technologies and modern materials to increase the reliability of the system; conducting technical and design supervision over the work.
Currently, the filtration fields, built over 60 years ago, are in critical condition: the maps are silted up, the drainage system is destroyed, the pipelines have lost their tightness, and there are no effective cleaning mechanisms. This leads to a low level of wastewater treatment (less than 40–50%), partial ingress of untreated wastewater into soil and surface waters, as well as sanitary and epidemiological risks for the population.
After the project is implemented, it is expected to achieve the target level of wastewater treatment of over 90%, complete elimination of unauthorized discharges, stable operation of networks throughout the year, and reduction of environmental pollution risks. This will allow the community to achieve environmental standards set by national and European regulations and ensure sustainable development of engineering infrastructure.
Problems and solutions resulting from project implementation
The key problems that need to be addressed are the critical technical condition of the filtration fields and centralized wastewater networks in the city of Sambor. Due to the high level of wear and tear of structures and pipelines, the system does not provide effective wastewater treatment, which leads to the release of insufficiently treated water into the environment, contamination of soils and surface waters, and also poses a threat to the sanitary and epidemiological safety of the population.
The urgency of the problem is due to the growth in wastewater volumes, in particular due to the increase in the number of residents, including internally displaced persons, and the need to bring engineering systems into line with modern environmental and European standards.
If the problem is not resolved, further destruction of the infrastructure, increased costs for emergency repairs, deterioration of the quality of water resources and a negative impact on public health are possible.
The implementation of the project will ensure the stable operation of the drainage system, increase the level of wastewater treatment, improve the environmental situation, reduce pollutant emissions, and increase the comfort and safety of community residents.

Results of the feasibility analysis
Economic Analysis
Social benefits and costs
The social benefits of the project include improved quality of public services for the population through the provision of sustainable water drainage and sanitary and safe wastewater treatment, reduced risk of disease due to improved water quality, and improved environmental awareness and safety of the community. Social costs include temporary inconveniences for residents during construction, such as noise, restricted access to some areas, and changes in traffic patterns, as well as possible short-term financial costs for the community to co-finance the project or partially cover the costs of the utility. Overall, the project implementation has a predominantly positive social effect that exceeds the temporary inconveniences, ensuring long-term improvement of the sanitary and environmental condition of the community.
Environmental benefits and costs
The environmental benefits of the project include reduced groundwater and surface water pollution through effective wastewater treatment, improved environmental conditions in the city and surrounding areas, and support for biodiversity by preventing the release of harmful substances into natural water bodies. Environmental costs are associated with the temporary environmental impacts of construction activities, including possible noise, dust, short-term disruption of the ecosystem in the construction area, and the consumption of energy and materials for reconstruction. Overall, the long-term environmental benefits outweigh the temporary negative impacts, ensuring the sustainable operation of the wastewater system and improving the environmental situation in the community.
Indirect benefits and costs
Indirect benefits of the project include increasing the attractiveness of the community for investors and residents due to improved engineering infrastructure, creating additional jobs during the construction and maintenance of the drainage system, as well as increasing public trust in local authorities through transparent and efficient management of municipal resources. Indirect costs may manifest themselves in the form of temporary restrictions for businesses and residents in the construction zone, a possible increase in utility tariffs to partially cover project costs, and administrative costs for organizing control and supervision over the implementation of the reconstruction. In general, the positive indirect effects of the project exceed the temporary negative consequences, contributing to the socio-economic development of the community.
