Lesson 9.

1. Прочитайте и переведите текст. Moscow waterworks.

Every day Moscow waterworks treat and supply approximately four million cubic meters of water. The system incorporates five by – drocentres, four water treatment plants – the biggest in Europe, and more than 4,500 km of water mains 0. It takes 500 million kwh annually to pump the water and convey it to consumers.

The Moskva River’s total flow is 29 cubic metres per second. Of this the waterworks system consumes 24. The balance is obviously much too small to maintain the normal regiment of the river. To mend the situation, water is discharge into the Moskva River from the Khimki Reservoir at a rate of 30 metres per second.

Moscow waterworks services may be conventionally subdivided into three units: water pumping, treatment and distribution; the operation and maintenance of the network; overhaul and repairs.

To bring water to the high requirements of the State Standard for Drinking Water it is purified by means of chlorination, filtration and disinfections. Water quality is under the continuous supervision of hidrobiological laboratories.

The stringent hygienic protection of water supply sources helps us to maintain the State Standard. Before being piped into the distributive mains, water is subjected to yet another chlorination. In future chlorination will be replaced by ozonification, and experimentation in this field is now under way.

The average daily per, capital household consumption in Moscow is 360 litres. Considering the personal water consumption at the place of work, the total per capita rate is approximately 560 litres a day. It is intended to bring this average up to 1,000 litres. This will call for the construction of a new hydrosystem on the Vazuza River, a tributary of the Volga’s upper reaches. The new system will have a daily capacity of 1,7 million cubic metres of high – purity water, and bring the Moscow waterworks capacity up to a daily rate of 6,5 million cubic metres.

A project is being prepared at present to use telemechanics and computer techniques to automatize the operation of: the water supply system in Moscow.
