 About us



 After the World War II there was the need in Slovakia to build up the water management - to ensure enough good quality water for different purposes, to produce energy through the construction of water structures, to protect the country against floods, to protect water courses against pollution by waster water and so on. Industrialization and urbanization went on quickly and therefore in 1948 the Government ordered to elaborate the State Water Management Plan as the basic document for the water managemnet development.

 Also in this connection the branch of the Water Management Research Institute in Prague was established in Bratislava on 9 January 1951. The founder and the first director of the insitute was a prominent hydrologist, academic professor Oto Dub.

 In 1958 the construction of the building on the Danube river bank was finished to accomodate the research workplaces of the institute, which were until then scattered on differenet locations in Bratislava. Among others there was also the hydraulic laboratory, established in two halls of the former exhibition area of the Danube fairs. Gradually also 13 external research and semi-operational stations  were built throughout Slovakia.

At the very begining the Department of Hydraulics was the most signifficant scientific-research pillar of the Water Research Institute (WRI). It elaborated many studies which were the backround for design and construction of large hydro-power and water management structures mainly in 1950s and 1960. The tenths of models were constructed and  the hundreds of research projects were implemented at the WRI for Gabčíkovo-Nagymaros water structures. In the mid 1960s the WRI aslo followed the world trend in the use of analogue computers and in mathematical modelling - it is the author of the world first published mathematical model of the water course morphological development.

In the 1960s the claims for drinking water supply increased and at the same time the problem of water pollution was more and more urgent. The WRI started to focus on water supply issues; departments of water protection, water treatment and water quality were formed. The insitute mapped the water quality of Slovak water courses and it explored the pollution sources which resulted into the elaboration of the first map of water quality of Slovak rivers. Similarly important was the multidisciplinary project implemented by 14 workplaces of former CSSR which was named Protection of Water Against Pollution by Oil and Oil Products and within which the WRI was the main coordinator and performer. Equally the attention was paid to ground water. In 1970s the task Water Resources at Žitný Ostrov and their Protection Against Pollution restulted  into the Plan of complex usage and  protection of Žitný ostrov water - with the possibility to use the amount of 18 000 l.s-1 quality drinking water without previous treatmnet.

Essential part of the WRI activities is the water analysis. The first tasks were the development and application of the methods for determination of COD, sulphates, organic and anorganic substances. In 1970s and 1980s the determination of different pollutants was elaborated in more details. Gradually new methods in organic trace analysis were introduced. In 1980s the gas chromatography dominated. In 1990s there was the development of instrumental techniques such as isotachoforesis, spectrophotometry, ionic chromatography, atomic absorption spectrophotometry with inductively bound plasma or gamaspectrometry.

Microbiology and hydrobiology have also a long tradition in the WRI. WRI research and science effort gave birth for example to a new original thinking within the biological water assessment. The work the Danube Saprobiology is still topical - results, methodology and the interpretation of values are valid even today. Right direction of water quality assessment of 30 years ago has also been confirmed by present  EU regulations.

All hydroanalytical activities were gradually concentrated in one unit and in 1997 the National Water Reference Laboratory for Slovakia was established. This workplace is focused on making analyses, development of new methods, the highest audit and it aslo provides the harmonization with EU countries.
