Local roads (district and municipal) play an important role in the road network, especially in rural areas. In recent years, these roads have been largely repaired, which was often associated with the construction of new infrastructure. One of the basic conditions of maintaining the quality of road works is the proper construction or renewal of drainage devices. Errors in this area result in lower durability of the road pavement. It is equally important to maintain these devices later in a good technical condition, which requires spending appropriate funds from local government budgets. The aim of the study presented in the article was to determine the current technical condition of drainage of local roads in the Czestochowa region and to identify the most frequent design and implementation errors, resulting in a rapid loss of functionality of drainage devices. They were based mainly on in situ studies carried out in the area of an exemplary rural municipality. Errors resulting in the lack of continuity of drainage, or the danger of a rapid loss of its functionality are shown with real examples. It was found that despite the shortcomings described, in recent years the technical condition of drainage of local roads has improved, which is related to the systematic overhaul of local roads (including the construction of sidewalks) and the local government's perception of the importance of road drainage problem.

Water shortages occurring in the natural environment are the result of progressing climate changes, including the decreasing amount of atmospheric precipitation. In Poland, during the vegetation periods, droughts occur every 4-5 years, which causes losses in the field production and in forest communities. Reducing the negative effects of drought is possible by retention of water within a catchment. This method of improving the water balance has been included in the provisions of the Water Framework Directive and Water Law. On the meliorated valley objects, there are melioration devices that enable regulation of the moisture content, including irrigation during periods of drought. Drainage ditches can also retain water in the early spring periods with high flows in rivers. The studies carried out on the Lower Supraśl river site showed that about 40% of drainage devices used for water damming (dams and ramps), as well as for water distribution (feeders and detailed ditches) are not technically efficient and do not fulfil the function of moisture content regulation. Fibrous-muck soils occurring on this object, due to the lack of rainfall and irrigation, reduced the water retention capacity by approximately 30%. Modernization and reconstruction of drainage devices on valley objects will enable increasing the retention within individual catchments.

The article presents technical aspects of maintenance of proper condition of drainage devices of public roads, and municipal and district roads in particular. The importance of road drainage is discussed, basic surface drainage devices discussed together with their location within the road. With use of actual examples we indicated the typical errors made during repairs and overhauls of the road, that have the consequence of disrupted continuity of drainage or the risk of quick loss of functions of drainage devices. The results of survey of technical condition of roadsides and the drainage device within a selected rural municipality were presented, indicating main problems of road keepers connected with keeping the drainage infrastructure in appropriate condition. The need of growing awareness in planning and designing road investment was indicated in the field of consequences of performing insufficient drainage.

W artykule przedstawiono techniczne aspekty związane z utrzymaniem właściwego stanu urządzeń odwadniających dróg publicznych, szczególnie gminnych i powiatowych. Omówiono znaczenie odwodnienia dróg, scharakteryzowano podstawowe urządzenia odwodnienia powierzchniowego i sposób umiejscowienia tych urządzeń w pasie drogowym. Wskazano, prezentując rzeczywiste przykłady realizacji, typowe błędy popełniane podczas remontu i przebudowy drogi skutkujące brakiem ciągłości odwodnienia, bądź niebezpieczeństwem szybkiej utraty funkcjonalności urządzeń odwadniających. Przedstawiono wyniki badań stanu technicznego poboczy i urządzeń odwodnienia powierzchniowego na terenie wybranej gminy wiejskiej i wskazano główne problemy zarządców dróg związane z utrzymaniem urządzeń odwadniających w odpowiedniej kondycji. Wskazano na potrzebę wzrostu świadomości przy planowaniu i projektowaniu inwestycji drogowych odnośnie skutków wykonania nieskutecznego odwodnienia.
