Kritická analýza skutečných a teoretických nákladů na snižování emisí fosforu do vodních toků: případové studie vodní nádrže Orlík

Water management planning is a key issue to secure its quality. Water quality, regulated in European Union by the Water Framework Directive 200/60/ES, is endangered by eutrophication, which is caused by phosphorus inflow into waters. One of the possible treatments is construction and reconstruction of wastewater treatment plants and sewerage. In order to determine theoretical wastewater treatment plant and sewerage costs, the Ministry of Agriculture created a methodical instruction. A study focused on reduction of water eutrophication in the Orlík dam basin found out that annual costs of a ton of phosphorus removed for measures realized in 2007 -- 2015 were four times higher than annual costs of a ton of phosphorus removed for additional measures to remove remaining phosphorus. Those measures were proposed on the basis of cost-effectiveness analysis using the methodical instruction. This thesis carries out a comparative analysis of theoretical and real wastewater treatment plant costs for selected projects in the Orlík dam basin and projects outside of the basin. The analysis found out discrepancy between the costs. It is concluded that this discrepancy is linked to some of the methodical instruction factors being outdated and also to insufficient specification of the objects included in the costs.
