Monitoring of wastewater from different types of sewer systems showed significant differences in mean concentrations of indicators of vacuum, pressure and gravity sewers. The results of monitoring of waste water at the pressure and vacuum system showed a higher concentration of contamination of raw sewage.

Paper describes design progres of surface drainage of residential area for approximately 1 800 inhabitants on area of 9 hectares (ha). Philosophy of rain water management is based on rain water drainage combined surface and shallow un-dersurface equipments connecting residential blocks with stream. Paper advert to several unusual factors, that are not occured in classic sewerage drainage of rain water. But in design used surface and shallow undersurface equipments these factors show cardinal importace for general conception of water drainage. Described is maximum investor effort to save money and possible negative impact on general conception of water drainage.

In the pilot project was built a model for partitioning and accumulation of yellow water. The object of the pilot project was to design and to verify an appropriate length of storage of yellow water so that it can be used in agriculture. The result is a recommendation to store 6-9 měsíclů yellow water before use.

Much has been written about this Moravian Village at the foot of the White Carpathian Mountains. It is renown for its environmental projects, it has been visited by many prominent personalities and it is considered an example of energy saving and environmental construction. This time, we have focused on a passive house that works as a model of environmental projects in rural areas.

Because the current regulations [2], [3] prefer rainwater infiltration, and there was no detailed technical regulation for drainage facilities design, then a technical tool [4] was issued and a new standard ČSN 75 9010 is being prepared, addressing the technical aspects of design, construction and operation rainwater infiltration facilities. This paper posts information about how design drainage facilities, which is in the draft of the new standard ČSN 75 9010.

Heavy metals impair the quality of water resources and the need for complex water treatment technologies. Dangerous is the capacity to accumulate heavy metals in plants and animal flesh, then at higher concentrations their toxicity. Monitored as mercury, arsenic, antimony, cadmium, lead, chromium, nickel.

Stormwater management is quite a new topic in Slovakia. There is no legal framework as well as standards or guidelines how to apply sustainable stormwater management techniques. As a consequence of repeated floods we are aware of a need for more effective stormwater handling. There are numerous techniques and approaches known around the world how to support sustainable stormwater management, especially in the urban areas, where the stormwater can cause significant damages. Nowadays we are more open to implement these new approaches especially in cases, where the effort is sustainability in stormwater management such as protection against floods and mitigation of pollution. The aim is to manage stormwater as close to source as possible which is also called source control covering number of measures. Rainwater harvesting as a part of the source control measures could contribute to the sustainability in stormwater management as well, by supporting potable water conservation and sustainability in water management in general. Submitted theoretical part of the thesis describes comprehensive stormwater management approaches as well as legislative framework.

Current legislation, in particular Decree No. 268/2009 Coll. and Decree No. 269/2009 Coll. prefer to deal primarily draining rainwater infiltration. The technical requirements for infiltration facilities in the Czech Republic are still lacking. ČKAIT issued a technical tool TP 1.20 in 2010 and now comes the new standard.

Sufficiency of drinking water and basic hygiene for all the people of the world till 2015 is one of the development objectives of the millenium. But it seems that it won't be realized. Sufficient availability of drinking water is defined as 20 litres of water per person and day at least. The source must be maximum 1 km away from the place of living.

Low energy (LEB) and passive buildings (PB) are becoming standard for new constructions in EU countries. They aren't experiments anymore, but absolutely ordinary mass production of sophisticated residential buildings. Only in Germany, Austria and Switzerland there are already thousands of buildings that meet the passive standard and their number doubles every year. The cost of passive buildings is only 5-7 % higher than those of conventional ones, and yet, their consumption of energy and heating is up to 90 % lower!
