 Catching Mineral Waters
The technical treatment of a source of mineral waters follows the stability of its hydrogeological regime, as well as stabilisation of the physical and chemical properties of the water. An unstable hydrogeological regime is demonstrated not only in changes in the yields, but also in changes in the physical/chemichal and bacteriological properties. The catching facility must also ensure balanced – even consumption.   [more...]



 Grain Island and Its Potential for Supply of Drinking Water
The Grain Island represents a territory with the most important accumulation of ground waters in Slovakia, and it represents a unique structure with huge resources of ground water, which is a unique reservoir of potable water in Europe.   [more...]



 Side Effects of Decreased Water Consumption
Development of need for water in foreign countries in many cases differs from the development in consumption in our country. Satisfaction of the requirements approximately by the end of the 70-ties used to be achieved in Slovakia in a way different from that in the world. While consumption in most European countries grew very slowly, consumption in our country grew very fast and followed the way of extensive development.

 Methodologic Procedures for Determining Protection Zones of Water Resources
Since the second half of 2002, protection zones of water resources have been determined according to a new legal regulation – the Act of the Slovak Ministry of Environment. For unified interpretation of this legal norm and for unified procedure in application thereof in practice, a methodologic instruction was prepared in 2003.   [more...]



 Removal of Fe and Mn from Ground Water in Situ
In 1900, a patent was registered at the Empire Patent Office in Germany by Mr. Oesten who formulated the basic conditions for water treatment in a rock milieu ("water treatment in situ").   [more...]



 Determination of Toxicity of Drinking Water
Various compounds of chemicals and microorganisms penetrate to the environment in the form of waste water discharged to rivers, but also in the form of solid waste ending in landfills with or without insulation of the subsoil.   [more...]



 Procedure in Sanitation of Individual Flooded Wells
Use of flooded water for drinking, cooking, and personal hygiene is inadmissible from the aspect of health protection of the population. An important preventive measure is observation of the prohibition to drink water from unknown sources and prohibition of bathing in places which may be assumed to contain contaminated water.   [more...]



 Territorial Protection of Water Resources for Drinking Water Supply
According to the method and scope of protection, the territorial protection of water resources is divided into general (according to the Water Law), broader - regional (PWMA and important water management regions), and strict, so-called special (protection zones - PZ and rivers and their basins).  [more...]



 Results of Solution of the Scientific and Technical Project
The Research Institute of Water Management in Bratislava resolved, during November 1995 - March 2000, a scientific and technical project "Research of Treatability of Drinking Water and Environmental Aspects of Rivers." The scientific and technical project was prepared by combination of two proposals for preparation of scientific and technical projects: "Water Supply and Water Resources Protection" and "Water Management Solution of Revitalisation of Rivers".   [more...]



 Quantitative Determination of Bioseston by Volume Biomass
The requirement for quality of supplied drinking water, which is given by the standard CSN 705 7111 "Drinking Water" is limited by the number of dead (50) and living (0) organisms v 1 ml of treated drinking water.   [more...]



 Microfiltration and Application Thereof in Treatment of Drinking Water in Slovakia
Due to insufficiently controlled discharge of municipal, industrial and agricultural waste waters, the quality of several ground and underground resources of drinking water in Slovakia has deteriorated. The volume of insoluble substances as well as the organisms included in the three basic communities, i.e. producers, consumers, and destructor has increased.  [more...]



 Small Water Reservoirs Database
The database is worked out, up-dated and actualised by the Water Research Institute yearly, this also is its administrator, its owner is the Ministry of Agriculture of the Slovak Republic - Water Management Section.
It is being used by solving of several tasks and problems in different spheres of the water management.   [more...]



 Evaluation of Climate Change Impact on Run-off
Effects of climate conditions on run-off conditions in river basins as a subject of mathematical modelling. In the area of impact assessment of potential climate change in our country these problems have been quite successfully addressed as part of the SR National Climate Programme and The Country Study Programme. Various methodical procedures for stipulation of the climate change impact.  [more...]
