Almost each country has potential for ensuring the sustainability of its economy if it avails itself of the opportunities offered by a nationally customized green economy strategy. To move towards a green economy, it will, however, have to introduce innovative technologies, techniques and processes. In particular, it will have to modernize its obsolete production and transport infra-structures and construction and cultivation methods. Green technologies can also contribute to the green economy because they have the potential to create new business opportunities, markets and jobs. This paper i) reviews the main environmental challenges and opportunities for the greening of the Košice region economy; ii) assesses the country’s innovation policies and the challenges and opportunities for the introduction of green technologies; iii) provide policy recommendations on adopting and applying innovative green technologies more efficiently. The strategy for adopting and applying innovative green technologies, also in Košice region, should carefully consider the current status of policy measures, challenges and opportunities which the country faces. Success depends not only on the improvement of each individual sector in region, but also on how these separate elements interact. Therefore, a wide range of consultations and interactions with stakeholders, such as the government authorities, business community, civil society, academics, researchers, scientists, financial institutions, etc., are essential to facilitate this interaction.

With the development of construction in large cities and their surroundings there is still more to tackle with congestion of sewer network. There are many alternatives that can reduce the risk of flooding, regulate the quantity and quality of groundwater. Most of these alternatives are proposed as a theoretical conversion according to standards. Infiltration practices represent one of the best methods of rainwater management which may effectively reduce load of interflow network. Rainwater management should be considered to be the sustainable strategy for reconstruction of rural and urban settlement from the aspect of environment, management and social criteria. Our aim in the paper is to compare the theoretical calculations with practice. We would like to stress that the hydrogeological survey is inevitable condition before design of any infiltration systems.

The paper presents the basic concepts of wasterwater – domestic, non-domestic as well as rainwater. The concept of drainage in cities, which aims to mitigate the impact of urbanization on the hydrological regime of the country and on aquatic ecosystems, come from our experiences and knowledge of current method of sewerage. New concept of capture and use water from surface run-off provides a platform for a new technical and non-technical measures, both in drained on each property, as well as the public part of urban drainage area.

River floods are considered one of the most important natural disasters in Europe as well as worldwide. It has now been widely accepted that the frequency and magnitude of river floods may increase because of climate change. Nevertheless, it can be complex, targeted measures to reduce their range and at least partially reduce the adverse effects. Floods do not respect boundaries, by the national, regional or institutional. Therefore, trans-boundary flood risk management is imperative – it involves governments – as borders are involved – and their people – as risk is involved. However, it is not easy to implement: joint monitoring, forecasting and early warning, coordinated risk assessment and joint planning of measures, and appropriate legal and institutional frameworks are all necessary. To support the transition from traditional flood defence strategies to a flood risk management approach at the basin scale in Europe, the EU has adopted Directive (2007/60/ES). The paper deals with overview about flood risk, flood risk assessment and basic principles of flood risk management.

The paper presents results of the Life Cycle Cost (LCC) analysis carried out for several variants of rainfall water management in a newly designed multi-family dwelling house. According to the LCC methodology, calculations were performed for the whole undertaking life cycle with both investment outlays and operation/maintenance costs taken into account. The LCC analysis was carried out, in particular, for a variant assuming that the rainwater collected from the roof will be entirely discharged to the sewage system. On the other hand, the second variant provided for replacement of traditional building roof with a green one. Facilities of that type, thanks to their retention properties, may delay runoff of rainwater and reduce the overall quantity of water discharged from roof surface and therefore can be classified as Sustainable Urban Drainage Systems. In the third case considered, rainwater is to be utilised in the building. It was assumed that precipitation water will be stored in a tank and used in the sanitary water supply system for flushing toilets, thus reducing the overall tap water purchase costs.

Przedstawiono wyniki analizy LCC dla kilku wariantów zagospodarowania wód opadowych dla projektowanego wielorodzinnego budynku mieszkalnego. Zgodnie z metodologią określania Life Cycle Cost wykonano obliczenia w pełnym cyklu istnienia przedsięwzięcia, uwzględniając zarówno nakłady inwestycyjne, jak i koszty użytkowania i konserwacji. Analiza LCC została przeprowadzona dla wariantu, w którym założono, że wody opadowe z dachu zostaną odprowadzone w całości do systemu kanalizacyjnego. Natomiast w drugim wariancie tradycyjny dach budynku został zastąpiony dachem zielonym. Tego typu obiekty dzięki swoim właściwościom retencyjnym mogą opóźniać spływ wód opadowych i redukować całkowity odpływ z powierzchni dachu, przez co zaliczane są do zrównoważonych systemów odwadniających (Sustainable Urban Drainage Systems). W trzecim przypadku zastosowano system gospodarczego wykorzystania wody deszczowej w budynku. Założono, że zmagazynowane w zbiorniku wody opadowe zostaną wykorzystane w instalacji sanitarnej do spłukiwania toalet, co pozwoli obniżyć koszty zakupu wody wodociągowej i wpłynie korzystanie na wyniki finansowe funkcjonowania obiektu mieszkalnego.
