Estimation of Volumes of Unorganized Wastewater Inflow into Sewerage System
A solution of quantitative estimation of unorganized inflow into the city sewerage on the basis of the analysis of climatic factors influence (Moscow as an example) is proposed. The methodology of calculation of volumes of surface and infiltration components of the inflow with regard to ecological and economic factors has been developed.

Improvement of Straining Equipment for Waste water Treatment
Wastewater coming to treatment facilities contains coarsedispersed substances of various origin (domestic garbage, wool, paper et. al). Litter retaining grates are installed to provide reliable operation of treatment facilities equipment. The technical solutions aimed at the use of different types of litter retaining grates that are introduced at the Moscow treatment facilities have made it possible to protect the Moskva River against entering of small litter.

Large-Scale Facilities for Biological Treatment of Wastewater with Removal of Biogenic Elements
A detailed analysis of the operation of the four technological lines of the Lyuberetskiye Treatment Facilities, where various technological and design solutions of organization of biological removal of nitrogen and phosphorous have been introduced, is presented. The experience of operation of aerotanks of different hydrodynamic profile demonstrates that as far as the wastewater with low concentration of organic compounds in the cities of Russia is concerned the plugflow bioreactors provide a more stable quality of treatment comparing with aerotanks with zones. The technological method of biological removal of nitrogen and phosphorus with the use of plugflow aerotanks has been developed; it has been realized in the projects of reconstruction of Kuryanovskiye and Lyuberetskiye Treatment Facilities of 1 mil. m3/day total capacity.

Treatment of Water Treatment Plants Sludge
Long-term experience of the decision of a problem of treatment of MSUE Mosvodokanal's water treatment plants sludge is recounted. Effects of reception of sludge for treatment at treatment facilities of city sewerage are described. The results of pilot tests of a separate process of mechanical dewatering of water treatment plants sludge are presented; a flow chart of dewatering realized at the Eastern Water Treatment Plant is given.

Influence of Filling with Treated Water on Ecological Condition of the Pekhorka River
During the last decades the ecological state of the Pekhorka River is defined by biotreated water whose portion in the total flow of the river amounts to about 90%. The retrospective evaluation of the river's ecological state has been made with the use of the archive data of the Moscow State Unitary Enterprise Mosvodokanal and hydrological, hydrochemical and hydrobiological observations carried out during 2000-2007 as well. To evaluate the fish population state the fish forage reserve at the present river regime has been studied.
Key words: activated sludge, domestic runoffs, hydrologic regime, fish forage reserve, river ecosystem. UDC 628.515.001.5
