Study of water consumption by the population of big cities under the conditions of non-round the clock water supply

Summary

The study of actual water consumption by the population of a city under the conditions of supplying water to the customers at intervals according to the schedule is presented. Histograms and diagrams of differential and integral distribution of specific water flow rate for buildings equipped with water and wastewater piping and bathrooms with local water heating were plotted. The exponential rule of differential distribution of actual water flow rates per one person per day has been determined that is a distinctive feature of non-round-the-clock water supply because at the continuous supply the differential distribution is subordinate to the normal law. Average weighted and 20-percent recurrence specific water flows were determined; the total reduction of water consumption by the population of a big city at non-round-the-clock water supply was revealed. The comparison with the water consumption by the population of Samara under the conditions of continuous water supply was carried out. The reduction of the specific water consumption at family increase regardless of the availability of public amenities in the apartment building was determined.
