Sustainable Water Management - Fashion or Necessity?
Despite the fact that the supply of water is renewable, the deficiency in water is deepening the world over. The problem no longer remains the concern of hot countries with a dry climate and poor in water, but more and more often huge urban agglomerations. It is the effect of incompetent water management. The solutions which are to bring balance into the water system are actions to locate and use alternative sources of water, recovering it and managing the water supply in such a manner that most of it remains in a hydrological circle. Such aims can be reached within limits of Sustainable Water Management, often also called Water Management (WM), Water Resources Management or Watershead Protection. Sustainable water management engages not only authorities and non-government organizations. It is also directed at society and calls for its support too. Acknowledging water to be a deficiency agent should promote its saving on many levels of social and economical life. Promoting watersaving technologies and creating regional water and sanitary programs especially in big urban agglomerations should serve this purpose. Balanced actions in regulating water supply in urban areas concern saving the biggest amount of drinking water. Management of rain water called Stormwater Management (SWM) or rainwater harvesting is the vital part of Water Management. Within limits of SWM such programs and strategies are used so as to gain, retention and using rain water. They include various techniques and equipment to manage rain water (rainwater harvesting techniques), combining them into one sustain able drainage system (SDS). SDS is mostly valued in urban areas. In the scale of the city actions of SWM there are among others, those directed to minimalising the threat of a flood by regaining retention and absorption areas. SDS equipment is opened and of a landscape character therefore it has a vital influence on creation urban space.
