2. Read the text and do the tasks that follow:

Water is one of the main factors in man’s life. We use water for domestic, sanitary and industrial purposes. In some localities water is available in unlimited quantities, in others providing a satisfactory supply of water becomes a large engineering task. A water supply system consists of a source of supply, a reservoir for storing water, a treatment plant for removing impurities from the water and a distribution system of pipes for delivering the water.

The development of human society has resulted in the changing of the composition of natural water resources. Rivers, lakes and ground waters contain today a great amount of products of mechanical, chemical and biological pollution.

The waste products are of two general types: sewage and refuse. Both sewage and refuse must be removed promptly. The removal of sewage is done by sewers which are a part of a sewerage system. Usual methods of sewage treatment consist of preliminary, primary, secondary or auxiliary treatment.

Rapid industrialization of our country has made the problem of water supply very acute. A number of decrees have been adopted to strengthen the protection of water resources. We need to find new ways of using water in industry and agriculture and of improving the technology of sewage purification.

Engineers specializing in water supply and water disposal, in rational use and protection of water resources are responsible for the fulfilment of this task. In Ukraine they are trained at some higher educational establishments. One of them is National University of Water Management and Naturel Resources Use.

During the training course at the faculty of water management future engineers obtain thorough knowledge of many sciences.

General scientific training is provided for by such subjects as history of Ukraine, political economy, philosophy, politology, higher mathematics, computer science, physics, chemistry, descriptive geometry, drawing, theoretical mechanics, strength of materials, electrical engineering, technology of metals, building materials, a foreign language etc.

General technical training is provided for by hydraulics, geodesy, hydrology, architecture, building constructions, building machines, heating and ventilation etc.

Special subjects include microbiology and chemistry of water, water supply, sewerage, sanitary engineering, pumps and pumping stations, safety engineering, production engineering, economics of water supply and sewerage systems etc.

The study of theory is accompanied by industrial and exploitation training.

Graduates of this speciality deal with surveying, designing, constructing and operating water supply and sewerage systems in residential areas and at industrial enterprises. They work as foremen, construction superintendents, design engineers, surveyors, heads of departments, research workers.
