This paper presents several cases of unrealized elevated water tank projects in the Czech Republic. It deals with the technical solution of unrealized objects and at the same time presents the reasons why the designers, official bodies or investors led to the search for another solution.
Water technology, water supply, waste water treatment
This paper introduces an initial effort at a systematic approach to the typology of elevated water tanks for the purpose of solving the research project Elevated water tanks – identification, documentation, presentation, new use. It builds on the previous definition of the terminology of the problem and the definition of the object of interest. From a typological point of view, elevated water tanks are seen as an integral part of larger technological units – water supply systems. In the framework of the basic division, the typology of elevated water tanks is based on the selection of parameters – the building situation of the tower reservoirs in relation to other objects, the function of elevated water tanks, the supporting structure, the shape and material of the accumulation tank, the number of tanks and the purpose of the object.
Based on existing phosphorus data series in the Slapy and Orlík reservoirs and their main tributaries, we reconstructed P inputs to the reservoirs from the catchment during 1961–2016 and compiled empirical models of P retention.
Clogging is a quite natural process, but it is an undesirable phenomenon in artificial wetlands used for treatment and tertiary treatment of wastewaters. Due to this, it is necessary, during proposal preparation and operation of artificial wetlands, to keep the principles that might significantly restrict the rise and progress of clogging.
The current situation in the field of water resources protection zones in the Czech Republic is problematic for a long time, not only in terms of their definition, but also the correct setting measures or data availability to the public.
Now is the time when even in the Czech Republic we have to save water. In our households do not use it for flushing toilets, used water reuse for irrigation, etc.
The issue of a new usage of industrial heritage (often referred to the concept of conversion) is the current trend of today. Also, water towers shutdown from water networks and stripped of their original mission can offer instead of decay or demolition attractive alternatives to new life.
Use of wastewater‑based epidemiology for monitoring of illicit drugs consumption in Czech and international context
This paper presents a brief summary of information about the project Determination of the amount of illicit drugs and their metabolites in municipal wastewater – new tool for obtaining of complementary data on illicit drug consumption in the Czech Republic and about the 2nd International Conference on “Wastewater‑based drug epidemiology“, which was held from 11.–15. 10. 2015 in Ascona, Switzerland.
Water quality in drinking water reservoir Švihov on Želivka river and its river basin, with focus on specific organic compounds
River basin of the largest drinking water reservoir Švihov on the Želivka River is distinctly anthropogenically affected both by direct human activities and also by the agriculture. The quality of the surface water is endangered in long-term period mainly by the eutrophication, pesticides pollution and erosion.
In this article results of analysis of future water withdrawals from water resources for public water supply systems are summarized.
The paper summarizes the „Methodology for comprehensive management of small water resources to ensure optimal quality of drinking water in normal and emergency situations“ that is a main result of the research project supported by the Technology Agency of the Czech Republic (TA 02020184).
Horizontal and vertical flow constructed wetlands belong among frequently used near-natural methods of treatment of wastewater from small municipalities in the Czech Republic. They consist of one or more filter fields connected in series or in parallel.
SWOT Analysis is a technique used to identify Strengths, Weaknesses, Opportunities and Threats related to a certain project, type of business, business plan, strategic investment, policy (meant as a measure), etc. This method of analysis is predominantly applied in marketing, but also in policy analysis and development.
At the time of changing climatic conditions and reducing the quantity of raw material it is necessary to start saving water and raw materials.
This paper deals with an industrial wastewater treatment utilizing waste heat from related industrial processes. This study proposes a possible solution, which is capable of reduction of industrial wastewater on one side and effective utilization of industrial excess heat on the other.
