Od kilku lat w Rzeszowie planowana jest budowa wewnętrznej obwodnicy północnej miasta, która ma odciążyć jego centrum od ruchu tranzytowego na kierunku wschód-zachód. Najważniejszym elementem obwodnicy będzie most nad Wisłokiem oraz sąsiadującym z rzeką zbiornikiem bezpieczeństwa Elektrociepłowni Rzeszów. Niniejszy artykuł prezentuje technologię budowy obiektu.

River valleys in large cities are not only precious environmental elements in their area, but they can also be an aim of a higher pressure on acquiring new areas for the settlement. In turn, the intensive settlement nearby a river can worsen the visual attractiveness of the river's vicinity and lead to such disadvantageous environmental effects as intersection of plants' and animals' migration channels, worsening of town's aeration and occasionally even an increased flood wave in a river bed narrowed by man. On the other hand,the main role of rivers and their banks in towns is often a recreational one. That is why it seems that not only local authorities and planners, but also the rest of the citizens, should influence the spatial management of river valleys. This assumption was a base for an introductory research on Rzeszów citizens' opinion on the Wisłok valley, which was conducted in March this year. 132 people living, working or studying in Rzeszów were surveyed. Over 40% knew the Wisłok valley well, because they go to the river bank several times a month. More than 80% of the questioned people especially liked the parks, alleys and natural green areas. In turn, they had a negative opinion on the increase in built-in areas at riverbanks. The results show that in Rzeszów citizens' opinion recreational, sporting and environmental functions of the Wisłok neighborhood are most acceptable. All this leads to a question if the Rzeszów society should take a greater part in the spatial planning process regarding the immediate vicinity of the Wisłok. It seems that the river flowing through the city needs some promotion so that its real value could be perceived.

There is a well documented groundwater aquifer to the North of the town Rzeszów. This aquifer is called the lower groundwater reservoir. In contrast very few is known about some aquifers located to the South of Rzeszow, except that in general they are of a small capacity, which is a general expectation for the most part of the Carpathian region. These aquifers are mainly of quaternary origin. The available bank of data refers to seventeen's, to the former hydrogeological atlases of Poland. These somewhat historical information were briefly summarised and the capacity of the upper reservoir evaluated first from hydrogeological atlases and then from the lowest flow rates in specific cross - sections of the Wisłok river.

Several methods of water loss prediction were characterised and compared in respect to the information able to be received. Water loses for the town Rzeszów were listed on a month base and for all regions and towns in the Wisłok river basin on a year base. These loses have been compared with the data known from other parts of the country and it was concluded that except of the region Strzyżów all other water supply systems lose less water than the average amount in Poland. Three more towns in the basin of a significant water loses are Iwonicz Zdrój (30%), Łańcut (24%) and Krosno (20%).
