Abstract

An experimental data-gathering project was carried out on two boulding aggregations of limited size in the urban area of Naples. Flow-rate measurements were continuously taken during a period of 24 h while the delivered volumes were recorded for approximately three years. The pattern of water demand in the day of maximum consumption is presented in a histogram of the hourly distribution which allows the hourly and istantaneous peak coefficients to be determined. The determination of the average daily consumption per year and the daily peak coefficient is made possible by the availability of quarterly invoicings.
