Analysis of Dependence of Water Consumption in Moscow on Outside-Air Temperature

Summary

To improve the accuracy of forecast of operation of a centralized water supply system the study of influence of ambient temperature on consumption of water of potable quality by the city has been conducted. From 2009 specialists of the Moscow State Unitary Enterprise Mosvodokanal (MSUE) make every day a forecast of daily water consumption in the city and also planning of daily and hourly water supply to the city by water supply facilities, thanks to it they managed to reduce considerably electric power expenses. The coefficient of water consumption growth for Moscow outside the zone of temperature comfort (over 25 ºC) has been determined. The data obtained make it possible to improve the accuracy of water consumption forecast and to designate optimal conditions of water supply to the city.
