REUSE OF WASTE WATERS IN SLOVAKIA, WATER SUPPLY SUSTAINABILITY

摘要

Continual population increase together with living standard has negative impact on local and global environment. The population produces the excessive amount of pollution through solid waste and wastewater. There are many possibilities how to solve this problem. The first one is to eliminate production of waste waters. The second one is to find the way how to disposal wastewaters. There are a lot of ways how to solve this problem, the possibility of wastewater recycling/reclamation, wastewater reuse, water price regulation, the setup of appropriate water demand. The next one problem is water acquiring in the water-poor areas, for example deserts and sea close areas with possibility of sea water but no potable water. The problem with water supply becomes very important not only in "dry" countries, but in some parts in Europe, following global warming - climate change. Water becomes the strategic raw, the production and distribution becomes rapidly expensive. The paper describes the types of alternative reuse of waste-water, the ways how to waste-water reuse with environmental protection aim, and how to protect the water sources with improving the waste-water management.
