Changes in the Russian domestic water supply in XXI century

Summary

The data on the provision of the public water services to the housing facilities of the constituent territories of the Russian Federation, on the share of leakages and unaccounted-for-losses in the total water amount supplied to the distribution networks (2001–2011) is presented. Regions with low access of the population to the public water supply and high levels of leakages are identified, e. g. the South and North Caucasian federal districts (around 35%). It is shown that depreciation of the water distribution network (50–70%) results in the increase of water leakages. It was found that underground water use decreased in all the Russian federal districts and now amounts in average to 45% of the total water supply; whereas the share of underground water in the domestic water supply balance stands approximately at the same level. The data on the dynamics of the water pass through pretreatment facilities is presented. The reasons of the significant reduction of specific domestic water consumption throughout the federal districts and regions of Russia for 11 years of the XXI century are stated. The improvement of the domestic water supply sources in most federal regions is noted. The information on the number of polluted underground water areas is presented. The fundamental RF laws and regulations in the field of water and wastewater management passed lately are cited. High priority measures to supply good quality drinking water to the Russian population are suggested, i. e.: developing standardization in the field of water conservation; ensuring the balance between affordability of high quality public services for customers and adequate financing.
