Artesian wells of the Moscow region of the 19th–20th centuries

Summary

A historical review is presented that describes the results of the completed stage of work on the search and study of underground water intake structures of the pre-revolutionary period in the Moscow Region. The materials presented concern mainly the so-called «artesian wells». These structures are scarcely covered in modern professional books. By design these wells had a large diameter and depth and were located above artesian boreholes. Their construction was caused by the need to place large-sized pumping units that were an integral part of the process of constructing an artesian well. The article presents a brief overview of such underground water intakes that existed as part of the city water pipelines in Moscow, documentary information on the methods of their construction, as well as a description of the artesian well discovered by the authors in Serpukhov, Moscow Region.

Purification of high-color low turbid water in the city of Kuibyshev, Novosibirsk Region

Summary

Drinking water has been an essential factor in shaping public health and living standards. Water quality is one of the priorities in the activities of the state sanitary and epidemiological service and municipal authorities. The reasons for the unsatisfactory purification of surface high-color low-turbid water at the water treatment facilities are considered. A new process flow scheme of two-stage water purification at the pumping station site of the city of Kuibyshev, Novosibirsk Region, providing the required quality of water with a design capacity has been developed. A full range of commissioning works was carried out with the determination of the process parameters of the facilities and development of the required documentation (standard operating procedures, flow charts, monitoring instructions, operating instructions). The clear organizational management, involvement of qualified specialists, introduction of effective methods, technologies and chemicals provided for solving the problem of bringing the quality of water purification of the Om River to the requirements of SanPiN 2.1.4.1074-01 «Drinking water. Hygienic requirements for water quality in public drinking water supply systems. Quality control. Hygienic requirements for ensuring the safety of hot water supply systems» in all parameters. The experience of solving the problems of purification of high-color low-turbid water of the Om River in the city of Kuibyshev, Novosibirsk Region is presented.
