Costs of water reclamation works in the Poznań district

Summary/Abstract: Water reclamation works, especially those related to their maintenance, are necessary wherever their lack may cause a risk to the natural environment, as well as human life and property. This paper presents the assessment of the maintenance costs on natural and regulated streams in the years 2010–2016 in the Poznań district. In the analyzed years, the costs for works on streams and water-drainage constructions amounted to an average of PLN 1214800 per year, which in terms of a 1 km of stream was about 3583 PLN/km per year. The costs of maintaining the streams after the flood in 2010 were twice higher and amounted to 6129 PLN per 1 km of stream. The amount of public funding for maintenance and current operation was only 5.5% of their annual demand.
