Change of Hydrological Regime and Water Quality Due to Reduced Wastewater Discharged into Surface Waters

Abstract

Wastewater discharge and treatment is today one of the priorities of strategic planning within the South Moravian Region and the whole of the Czech Republic. Wastewater drainage and its subsequent cleaning are basically resolved with respect to the adoption of EU legislative conditions in the Czech Republic for municipalities with more than 2000 inhabitants. Attention is now being directed to municipalities with fewer inhabitants. Existing wastewater treatment plants are currently focusing mainly on the removal of phosphorus from wastewater. Significant amounts of phosphorus in wastewater and its insufficient removal by treatment plants causes problems with eutrophication of surface waters, especially in tanks [1]. The problem of eutrophication and increased concentrations of pollution in tanks has also multiplied in recent years due to high

Public recreation and landscape protection - with environment hand in hand…

“…The concentration of nitrates in natural waters is increasing as a result of population growth and agricultural activity (Hubačíková et al, 2020). The primary function of the vegetation on the revitalized site is bioremediation, in our case phytoremediation or phytodegradation.…”

“…The quality of water in water reservoirs intended for recreation changes during the year. The problem of eutrophication and increased concentrations of pollution in tanks has also multiplied in recent years due to high temperatures and droughts, where minimal inflows into tanks and increased evaporation cause low water levels in reservoirs and consequently increased concentrations of pollutants (Hubačíková et al, 2020). Eutrophication is also associated with blooms of toxin-producing cyanobacteria.…”

Water in the City and Remote Sensing

“…In the context of climate change now, we will continue to face similar challenges. The situation caused by a new phenomenon due to dry years when there is a minimal influx of surface water from precipitation and a significant source of overheating occurs in built-up areas (Hubačíková et al 2020).…”
