The main problems and needs (described in Annex 2) affecting the need to implement the investment include: 1) Water loss problem: a) actual flushing of the network, water theft, flat-rate points, water used for construction purposes from hydrants, water used for fire protection purposes. b) apparent - these are losses resulting from inaccuracies and ambiguities of measurements, i.e. so-called measurement errors resulting from poorly selected measuring devices, metrological errors, water theft. 2) The problem of water deficit - occurs in summer periods, i.e. there is a greater demand for water by the inhabitants of the Pysznica commune than water extracted and pumped into the network, which results in: - low pressure in water supply networks, and at the final partitions even lack of water - large pressure fluctuations in water supply networks cause a decrease in the strength value of pipes, cause cracks, deformations, which affects the failure of the network and thus water supply interruptions and water losses. - problems with incorrect water pressure and lack of proper water regulation contribute to an increase in electricity consumption. 3) Exceedances of manganese and iron in excavated water -manganese water-sediment easily precipitate and accumulate at a rapid rate in domestic installations and water supply network, can occur local overheating, decrease in efficiency, significant reduction in the light of pipes, costly failures can occur. Manganese sediment is an excellent environment for the development of various types of microorganisms. biofilm and the possibility of bacteriological contamination of water. The aim of the project is to increase the availability of drinking water, improve the quality of the water supply system and reduce water losses along with improving the efficiency of its use in the Pysznica commune for over 11,000 inhabitants of this commune. The project includes: 1) Preparation of the project 2) Preparatory works of the investment 3) Construction works 4) Settlement of the investment As part of the project for the currently operating water treatment station in Pysznica, it is planned to expand the technological part, expand the filter hall, build 2 pcs. of treated water tanks with a capacity of 500m3 each and replace existing pipelines from wells to strokes as well as make new inter-object pipelines. In the new part of the filter hall, a technological series will be created consisting of 4 new filters equipped with a set of stainless steel fittings and pipelines. The filters will be covered with a catalytic bed on the quartz ballast. The built-in building of the filter hall will be plastered from the inside and ceramic tiles will be laid on the floor and walls, and from the outside it will be insulated and thin-layer plaster will be located. In the area of the water treatment station, two treated water tanks with a capacity of 500m3 each will be made. Tanks will be made in reinforced concrete technology poured on site. The tanks will be insulated and covered with trapezoidal sheet, the top cover will be equipped with two stainless steel hatches and protective barriers. Outside and inside will be made of stainless steel ladders. Pipelines will be supplied to the reservoir which will connect the stroke building with the reservoirs and drain and overflow pipelines will be supplied. New pipelines will be introduced to the deep wells to ensure an adequate flow of raw water without resistance. The wells will be equipped with new control and monitoring systems, power and control cables will be replaced. The control system of water treatment plant equipment will be expanded. As part of the works related to the extension of the strokes, minor construction works will be carried out to restore the original state of the existing walls and floors. Internal sanitary and electrical installations will be replaced.
