Abstract

In this paper, we deal with the method of calculation water consumption for design of piping and water uses in multi-storey flats. The current design procedure which is used to determine the size of piping is the Hunter's method utilizing fixture unit, but with this method we cause several problems such as over design of piping. Here, the results of one study based on the actual investigation of two multi-storey flats are described as follows; 1) The amounts of water consumption in various uses are analysed. And we explain that we can save the amounts of water by taking various means in using water. 2) The patterns of use of water outlets are investigated. And it becomes clear that the probability of simultaneous uses of water outlets can be approximated with the Poisson distribution. 3) A procedure that is used for the probability of simultaneous uses of water outlets is suggested for flow rates design. The calculated results based on investigated data of the probability, give small values in comparison with the Hunter's loading curve.
