DWARF

About the project:

Increasing levels of Dissolved Organic Matter (DOM) is a large challenge for Drinking Water Treatment Plants. Surface water is the source for more than 50% of drinking water in the Czech Republic. In the region of South Bohemia surface water supports drinking water for more than 350 thousand people from the reservoirs (Římov, Husinec, Jordán) and Otava River. Catchments of these sources will be characterized with respect to the sources of DOM and their temporal and spatial variability resulting in a map of DOM sources with future predictions. A methodology for outflow control in reservoirs to minimize the effect of flood events with high DOM levels will be developed. A cooperation among basin authorities, drinking water producers and Czech and Norway research partners will be established.

2021

During the first year of the project DWARF – Drinking WAter Readiness for the Future we stared collecting of historical data for water quality in the catchments of studied drinking water treatment plants. Studied catchments were mapped and described regarding land-use, forest quality, and geology. Water samples were collected regularly in different season to get detailed data on chemical quality of raw water. Pilot experiment of flotation technology was conducted at drinking water treatment plant Studená to test its ability to remove increased concentrations of dissolved organic matter.

2022

During the second year of the project DWARF – Drinking WAter Readiness for the Future we finished collecting of historical data for water quality in the catchments of studied drinking water treatment plants. Studied catchments were mapped and described regarding land-use, forest quality, and geology. Water samples were collected regularly in different season to get detailed data on chemical quality of raw water. Mathematical models of DOC in Římov reservoir and its catchment were created and tested. The first version of map of DOC export from the Římov reservoir catchment was created.
