The project includes tasks related to the construction of the sanitary sewerage network in Bóbrka, Solina, Bereżnica Wyżna, Bukowiec and Terka, in the Solina Commune. These are activities that, in the planning documents of the Commune of Solina, constitute designated directions of actions aimed at improving the management of urban wastewater. The requested task is consistent with the National Urban Waste Water Treatment Programme , as the main instrument for the implementation of Council Directive 91/271/EEC, for the construction of a sewage network in Bóbrka and Solina with a total length of 4,674 km (in the Solina agglomeration of 6 690 p.e.), Bereżnica W. with a length of 6,884 km (in the Polańczyk agglomeration of 9 690 p.e.) and Bukowiec and Terka with a debt. 6,059km (in the Volkovaya agglomeration with a p.e. of 5 504). The investment is a stand-alone wastewater management project that does not provide for water supply infrastructure elements. The project does not concern the management of sewage sludge. The project is a response to the needs of the above-mentioned agglomerations in terms of achieving the level of sewage treatment in accordance with the Waste Water Directive. Currently, the level of sewerage in agglomerations is: Solina 82.77%, Polańczyk 85.91% and Volkovaya 66.81%. The implementation of the investment will lead to an increase in the degree of sewage treatment in individual agglomerations to the required level of 98%, which in turn will allow achieving the next 2 conditions required by the Wastewater Directive regarding the efficiency of the treatment plant (by increasing the amount of wastewater delivered, the operating parameters of the treatment plant will be improved) and treatment standards (by increasing the amount of wastewater affecting the treatment plants, the standard of their treatment will also be improved). The scope of the investment also includes the installation of PV installations at the plants in Solina and Berezka with a capacity of 49.59kWp and 49.59kWp, respectively. The receiver of waste water treated from all the agglomerations is the standing water (Solin and Myczkowce reservoir) of the San River, the longest river in the Bieszczady Mountains and one of the most beautiful mountain rivers in Poland, subject to sectional protection. The protection of the San River by reducing pollution by, among others, municipal wastewater is also the protection of San, and further the Vistula and the Baltic Sea, hence the important actions aimed at improving the quality of San waters by increasing the amount of treated wastewater. Insufficiently solved wastewater management, including equipment for agglomerations that do not meet the requirements of the Wastewater Directive, is one of the most important threats to the environment, which leads to pollution primarily of soil, surface water and groundwater. Currently, sanitary sewage from unscanned households in the agglomeration is discharged into drainless reservoirs or through a settling tank with a very different retention period into drainage ditches. Most sewage tanks and settlers were already built as absorbent wells, without maintaining tightness, in order to reduce the amount of sewage exported by the slurry tanker. Leakage of backyard reservoirs will lead to groundwater contamination and lead to a number of diseases in residents using water intakes based on a polluted groundwater reservoir. Untreated effluent from farms entering directly into receivers will contribute to further degradation of surface water. The effects can be irreversible for the environment and worsen the comfort and health of residents. The overall objective of the project is to protect and improve the state of the environment, including water resources, through effective wastewater management. The achievement of this objective will result from the implementation of a project which, through the construction of a sanitary sewerage network in: Beaver, Solina, Bereżnica Wyżna and Bukowiec will achieve all 3 conditions required by the wastewater directive, and above all reduce environmental pollution by developing wastewater infrastructure and improving the state of wastewater management.
