Optimization of rural environment through drainage system modernization: analysis of investment feasibility indicator in the modernization of drainage ditches on former agricultural lands

The benefits of installing pipes and drainage manholes, as well as covering open drainage ditches in built-up areas, have been listed in the report. A cost-effectiveness indicator for the investment, taking into account proprietary weighting coefficients, has been presented, which can be used as a formal argument determining the need for modernization of existing solutions in built-up areas. The indicator serves as an objective tool in the decision-making process at the municipal level. Modernization involving the installation of pipes and covering ditches, which previously served agricultural purposes, leads to an improvement in spatial order in a given area and also contributes to the protection of the natural environment through proper water management in former agricultural areas
