The problem of pure drinking water is one of the sharpest for a lot of cities and of countries. Ways of a solving this problem are defined today not level of development of science and technology, as sufficiently efficient technologies for getting given quality drinking water are designed, but in greater degrees by financial possibilities of country on the modern water supply stations building and current it is costs payment on the usage of these stations. For developing and comparatively non-rich countries will possible turn out to be an interesting a work of Ukrainian experts, directed on creation for the cheap water preparing, ensuring under small capital embedding and field-performance expenses necessary quality of drinking water.

The program of work on maintenance of the inhabitants of industrial city by qualitative drinking water including the use of new two step reagent technology of water preparation and its introduction without any reconstruction on acting water supplying plants, electrical pulsing and light disinfecting of water, creation of manufacture of local installations for disinfecting of water without chlorine processing.

Increasing water pH to 11 will result in deposition of magnesium hydroxide and calcium carbonate under certain conditions in a mixing/precipitation tank. More than 90 % of the heavy metals and radionuclides, over 80 % of the organic contaminants and all bacterial pollutants are removed in the process. The final step is water neutralization with a hydrolysing coagulant (salt of aluminum or iron) for further purification. All additives are readily available. A mixing/precipitation tank is the only necessary addition to the existing equipment. The present practice allows to carry out a complex clearing of water from heavy metals, (Fe, Mn, Al, Be, Cu, As, Pb, Zn, Se, Cd, Ti, Ni, Hg, Cr etc.); radioactive elements, (U, Th, Pb-210, Po-210, Sr-90,.As-137, Ra-226); petroleum, pesticides, other organic inclusions with simultaneous water disinfecting without the application of chlorine and operating time of cancerogenous -organic derivatives. The level of water purification from this elements and combinations is from 92 to 98 percents, what is best in compare with traditional «chlorine» water purification technology in all municipal water treatment plants in the former Soviet Union. It is possible to summarize the project results for spinning off to other areas in Ukraine and developing countries.
